These are the questions customers ask us before they spend their money on solar. Search for yours below, or read a full article, including our illustrated battery guides. Can’t find your question? Send it to us on WhatsApp and we’ll answer it here.
It depends on three things: the system size in kW, whether you add batteries, and the structure your roof needs. Panel and inverter prices in Pakistan move every few weeks, so any fixed figure online goes out of date quickly. Send us your last 12 months of electricity bills and a few photos of your roof on WhatsApp. We will send you a written quote for your house, with every item listed.
Sizing starts from your units (kWh), not the rupee amount. As a rough guide in Punjab, each 1 kW of panels produces about 110–150 units a month, depending on the season. Take your average monthly units, look at your summer peak and decide how much backup you want. Under the 2026 rules, the system is also capped at your sanctioned load. We work this out from your bill history before we recommend a size.
Yes. A 1.5-ton inverter AC usually draws about 1–1.5 kW while it runs, so it needs roughly 2 kW of panels to run through the day with some margin. Running ACs at night means drawing from batteries or the grid, and battery backup gets used up quickly with ACs. Tell us how many ACs you run and for how many hours, and we will size the system around that.
Most solar equipment is imported. Its price follows international module prices, the rupee–dollar rate, import duties and taxes, and local stock levels. Any of these can move within weeks. That is why we give quotes with a validity date instead of publishing fixed prices.
On-grid: lowest cost, but no backup during load shedding. Surplus is exported at the lower buyback rate.
Hybrid: solar plus batteries plus grid. It gives backup and lets you use more of your own solar. Since 2026 this is the right choice for most homes.
Off-grid: no grid at all. Suits farms and sites with no connection, but needs the most battery.
It follows your electricity connection. A single-phase connection needs a single-phase inverter, and a three-phase connection needs a three-phase inverter. Your bill and meter show which you have.
Larger homes with several ACs are usually on three-phase, and a three-phase system also means spreading loads evenly across the three phases. If you are about to raise your sanctioned load, decide the phase first, because it changes which inverter we fit.
Yes. Charging in the daytime straight from solar is the most economical way to run an EV or electric bike. An electric bike or scooter adds only a small load; an electric car adds much more, so it needs to be planned into the system size.
Charging a car at night from a home battery drains it quickly, so night charging usually comes from the grid. Tell us about the vehicle at the survey and we will size for it.
Usually not. Panel prices in Pakistan have already fallen a long way, and nobody can promise how much further they will go. Every month you wait is another full electricity bill.
Rules can also move against late buyers, as net billing did in February 2026. Buy when the numbers work for your house; there will always be a newer panel next year.
Choose an on-grid Sungrow (SG-RS single-phase or SG-RT three-phase) if your main goal is a lower bill through net billing and you can live without solar during load-shedding. Choose a Sungrow hybrid (SH-RS single-phase or SH-RT three-phase) if you also want backup during outages, because only a hybrid with a battery can keep selected circuits running when the grid is off.
An on-grid inverter must switch off when the grid goes off. That is a safety rule, not a defect. A hybrid powers a separate backup circuit from the battery and panels, so we plan which appliances go on that circuit.
Send us your bills and tell us how long your load-shedding usually lasts. We will suggest the right type and size in a written quote.
Choose a SOFAR on-grid inverter (KTLM single-phase or KTLX three-phase) if you mainly want a lower bill through net billing and can live without solar during load-shedding. Choose a SOFAR hybrid (HYD or ESI series) if you also want backup, because only a hybrid with a battery keeps selected circuits running when the grid is off.
An on-grid inverter must switch off when the grid goes off; SOFAR shows this as IslandFault. A hybrid powers a separate backup (EPS) circuit from the battery and panels, so we plan which appliances go on it.
Send us your bills and your usual load-shedding hours and we will recommend the type and size in a written quote.
It depends on whether you want net billing, backup, or both. Growatt MIN (single-phase) and MOD/MID (three-phase) are on-grid inverters for lowering your bill through net billing; they stop during load-shedding. SPH is a hybrid that does both, with a battery and a backup (EPS) circuit. SPF is an off-grid inverter that runs your loads from solar and battery and uses the grid or a generator to charge and pass through.
The SPF models in our manuals are off-grid units, so they do not export to the grid for net billing.
Send us your bills and load-shedding hours and we will recommend a series and size in a written quote.
The SUN2000-L1 is Huawei's single-phase home inverter that can also take a high-voltage lithium battery and run off-grid (backup) loads. The SUN2000-M1 and M2 are three-phase inverters for homes and businesses with a three-phase connection.
Pick by your connection first: single-phase house, L1; three-phase supply, M1 or M2. Then decide whether you need battery backup for load-shedding.
Send us your bill and tell us your phase type and load-shedding hours, and we will recommend a model and size.
GoodWe XS, MS and DNS are single-phase on-grid inverters for net billing. SDT is the three-phase on-grid range. ES (including ES Uniq) is a single-phase hybrid with battery and backup, and ET is the three-phase hybrid.
On-grid models stop during load-shedding. Hybrids keep a backup circuit running from the battery and panels.
Tell us your phase type, bills and load-shedding hours and we will recommend a model in a written quote.
Solis S6-GR1P (single-phase) and S5/S6-GR3P (three-phase) are on-grid inverters for net billing; they stop during load-shedding. The S6-EH1P is a single-phase hybrid with battery backup, and S6-EH3P its three-phase version. The S6-EO1P is an off-grid inverter that runs loads from battery and solar.
Pick by phase type, whether you need backup, and whether you want to export to the grid.
Send us your bills and load-shedding hours for a written recommendation.
Fronus X1-Genki (single-phase) and X3-Genki (three-phase) are IP65 hybrids with battery backup. X3-MIC, X3-PRO, X3-MEGA and X3-FORTH are three-phase on-grid inverters for net billing. Infineon Reborn and Platinum are IP21 indoor hybrid/off-grid style units.
Pick by phase, backup needs and whether the inverter will be indoors or outdoors.
Send us your bills and load-shedding hours for a recommendation.
Sineng SN PT is a three-phase on-grid range for homes and small businesses on net billing. SN HS is a single-phase hybrid and SN HT a three-phase hybrid, both with battery backup.
On-grid models stop in load-shedding; hybrids keep a backup (EPS) circuit on.
Share your bills and phase type for a recommendation.
SolaX X3-MEGA and X3-NEO are three-phase on-grid inverters for net billing. X3-Hybrid G4 and X3-ULTRA are three-phase hybrids with battery backup; X3-AELIO suits larger commercial storage. Several Fronus X-series models are built on SolaX platforms.
On-grid models stop in load-shedding; hybrids keep a backup circuit on.

Solplanet ASW S models are single-phase on-grid, ASW LT three-phase on-grid, and ASW H-S / H-T hybrids with battery backup. Knox on-grid three-phase inverters in Pakistan are built on the Solplanet (Aiswei) ASW LT-G2.
On-grid models stop in load-shedding; hybrids keep backup on.
Share your bills and phase type for a recommendation.
SAJ R5 and R6 are on-grid inverters (single- and three-phase) for net billing. H2 is a hybrid with battery backup, and HS3 an all-in-one hybrid with battery. M2 is a microinverter.
On-grid models stop in load-shedding; hybrids keep backup on.

Since 9 February 2026, new connections are on net billing. Exported units are bought at close to the national average energy purchase price, currently around Rs 8–11 per unit. The units you draw from the grid are still charged at your normal slab tariff, which is several times higher. That makes each unit you use yourself worth far more than a unit you export.
If your net metering agreement was signed before 9 February 2026, its terms continue until the agreement expires. New applicants are on net billing. Talk to us before you raise your sanctioned load or extend a grandfathered system, because doing so can end that protection. The rules may change again, and we keep this answer updated.
It depends mostly on how much of your solar you use yourself. Each unit you use saves your full slab tariff; each unit you export earns only the buyback rate. The more you self-consume, the faster the payback.
That is why systems sized to your own daytime load, with a battery for the evening, pay back faster under net billing than oversized export systems. We calculate it from your bills rather than quoting a general number.
Yes. With a meter connected, the installer can set Export Control on SolaX X3 inverters, from full export down to zero. If the meter is fitted the wrong way, the inverter shows IE 01 and the installer can enable meter reverse.
Once net billing is approved by FESCO or LESCO, the limit can be raised.
Only if it has batteries (hybrid or off-grid). A plain on-grid system switches off when the grid goes down. A hybrid system switches to its batteries, and to its panels during the day, so your chosen loads keep running.
It depends on two things: the usable capacity of your battery and what you run at night. Fans, lights and a fridge can last through the night. ACs use up a battery far faster. We size the battery around the loads you choose and the hours you need, and we set up a backup reserve so the battery keeps a margin for load shedding.
For most homes in 2026, yes. The reason is money, not technology. Under net billing, a unit stored and used at night saves you the full tariff, while an exported unit earns only the buyback rate. Batteries also give you backup during load shedding. If you mainly use power in the day and don't need backup, on-grid alone can still work.
For daily solar cycling, lithium iron phosphate (LiFePO₄) generally lasts much longer. It lets you use more of its capacity, needs no water top-ups and takes less space. Tubular batteries cost less up front but wear out sooner with daily cycling. Whichever you choose, the battery must be approved for your inverter and installed properly. Matching voltage alone does not make a battery compatible.
Lithium battery life depends on how many cycles it goes through, how deeply it is discharged, and the temperature where it is installed. Check the cycle rating on each model's datasheet. New batteries we supply carry the manufacturer's warranty for that model, given to you in writing with the quote. Tubular batteries under daily solar use usually need replacing much sooner.
A low-voltage (LV) battery runs at around 48 V; a high-voltage (HV) battery stacks modules to run at a much higher voltage. For the same power, HV carries far less current, which suits larger hybrid systems, often three-phase.
Most single-phase homes use 48 V batteries. HV makes sense for bigger homes and businesses with an HV hybrid inverter. Either way the battery must be on the inverter maker’s approved list: a similar voltage alone does not make them compatible.
For most homes with a hybrid system and battery, no. The battery covers normal load shedding. A generator still makes sense for long outages, fog weeks with little sun, heavy loads such as factories, or sites where power must never stop.
If you keep one, it must connect through the inverter’s generator input where the model supports it, or through a proper changeover, never straight into the solar wiring.
Not directly to a Sungrow SG-RS or SG-RT on-grid inverter, because they have no battery port. You can add a Sungrow hybrid (SH series) with a battery alongside your existing single-phase on-grid inverter; Sungrow's manual describes this as retrofitting an existing system.
In that set-up the old inverter keeps working, and its solar power goes to your loads first and then helps charge the battery. The old inverter must not be bigger than the hybrid, and the hybrid's meter needs a second sensor to read the old inverter.
Whether it suits your house depends on your wiring and which circuits you want on backup. We survey first and then quote.
When the grid goes off, a Sungrow hybrid switches its backup circuit to battery and solar power within a fraction of a second (Sungrow states under 10 milliseconds), so most lights, fans and routers carry on. Only appliances wired to the backup circuit get power.
Backup continues as long as the battery or panels have power. If the battery reaches its minimum level, backup stops and the inverter recharges the battery first when power returns. If the backup load is too high, for example an AC and a pump starting together, it protects itself and restarts after a short delay.
Sungrow says backup is not guaranteed in every situation and is not for life-support medical equipment. We help you decide which circuits go on backup.
Yes, that is what the ME 3000SP is for. SOFAR describes it as an AC-coupled battery converter that adds storage to an existing solar system, so your current on-grid inverter stays in place.
In auto mode it charges the battery with surplus solar and discharges it to run your loads when solar is not enough. It can also work on a time-of-use schedule.
Whether it gives the backup you want depends on your wiring and which circuits you need during outages. We survey first and then quote.
When the grid goes off, a SOFAR hybrid switches its backup (EPS/LOAD) circuit to battery and solar power in a few milliseconds (SOFAR lists 4 ms by default on the HYD-EP), so lights, fans and routers carry on. Only appliances on the backup circuit get power.
Backup continues while the battery has charge. When the battery reaches its low level, the inverter stops discharging to protect it. If loads are too high, for example an AC and a pump starting together, it reports overload and cuts backup.
Some SOFAR hybrids can also start a generator for long outages. We help you choose which circuits go on backup.
Yes. Growatt SPF inverters support lithium batteries with BMS communication over CAN or RS485, as well as lead-acid batteries. For lithium, the communication cable and the correct BMS protocol setting must be in place, otherwise the inverter shows a BMS communication warning.
The battery's voltage must match the inverter's battery voltage (for example 24 V or 48 V models), but a matching voltage alone does not mean the battery will work correctly; the model and protocol must be supported.
Tell us your SPF model and we will confirm a suitable lithium battery before quoting.
Some Growatt SPF models come in a parallel version. The SPF 3000TL LVM parallel model, for example, can run up to six units together, including three-phase arrangements.
Parallel units need matching settings, parallel and current-sharing cables, and correct neutral wiring. Mistakes show up as parallel warnings and faults, so this is a job for an experienced installer.
If your load has outgrown one SPF, we can assess whether adding units in parallel or moving to a larger hybrid makes more sense.
When the grid fails, a Growatt SPH switches its EPS (backup) circuit to battery and solar; Growatt states a typical switching time of 10 ms. Only appliances on the EPS circuit stay on.
If the EPS load is too high, the SPH reports overload. Growatt notes that after three overload warnings the off-grid function is locked for an hour, so it is important to keep heavy loads like ACs off the backup circuit unless the system is sized for them.
We plan which circuits go on EPS when we design your system.
The SUN2000-L1 uses a high-voltage lithium-ion battery, not a 48 V battery bank. Huawei's LUNA2000 is designed for it.
A low-voltage battery that suits most local hybrid inverters will not connect directly to an L1. Always check the battery is approved for the exact inverter model.
We confirm battery compatibility before quoting.
A grid-tied Huawei inverter (for example most M1/M2 set-ups without a battery and backup wiring) stops when the grid goes off; it shows Grid Loss. A SUN2000-L1 with a battery and backup wiring can run selected loads off-grid; its LEDs turn orange in off-grid mode.
If the backup load is too high, the L1 retries every 5 minutes and, after three failed attempts, waits 2 hours. So we keep heavy loads like ACs off the backup circuit unless the system is sized for them.
We plan backup circuits as part of the design.
When the grid goes off, a GoodWe ES or ET hybrid moves its backup port to battery and solar power so the loads on that circuit keep running. Appliances on the main board without backup wiring go off.
If backup loads are too high, it reports Back-up Output Overload (F55) and you need to switch some loads off. Some models can also work with a generator.
We decide which circuits go on backup when designing the system.
A Solis S6-EH1P hybrid switches its backup port to battery and solar in under 10 ms (Solis states this for the S6-EH1P-L), so lights, fans and routers on that circuit keep running.
If backup loads are too high, or a motor's start-up surge is too big, it shows Over-Load; Solis says to remove some backup load or move inductive loads off backup.
We plan which circuits go on backup.
The S6-EO1P is a Solis off-grid inverter: it runs your loads from solar and battery and can use the grid or a generator for charging, with a typical transfer time of about 10 ms. It suits homes and shops that need power through long outages.
It works with lithium (with BMS communication) or lead-acid batteries. It is not a net-billing inverter.
We size the inverter and battery to your outage hours and loads.
The Genki reports backup overload in steps: 1.05, 1.25 and 1.5 times its rating. If overload continues it locks itself (EPS_OVERLOAD_LOCK) and needs heavy loads off and a restart.
Keep ACs, irons and pumps off the backup circuit unless the system is sized for them.
We plan backup circuits during design.
Sineng SN HS and HT hybrids power an EPS (backup) circuit from battery and solar when the grid goes off. If backup loads exceed the rating, they report EPS Overload (Alarm 12) or EPS over current (55).
The EPS neutral must be wired correctly to the grid neutral; Sineng reports Alarm 16 if not.
We plan and wire backup circuits during installation.
Yes, the ASW H-S (single-phase) and H-T (three-phase) hybrids run a backup circuit from battery and solar when the grid is off. On-grid ASW S and LT models do not.
We plan which circuits go on backup.
The SAJ H2 runs a backup (off-grid) port from battery and solar when the grid goes off. If backup loads are too high, the battery is low or too hot or cold, it reports OffGrid Voltage Low (16) and you should reduce the load.
A short on backup wiring shows Output Shorter (17).
We plan backup circuits during design.
Yes, but output drops. Heavy smog and fog block part of the sunlight, and on the worst days in November–January output can fall sharply. Panels still produce power in diffuse light. Bifacial and N-type panels handle low light somewhat better. Plan for these weeks when you size the system and battery.
Winter days are shorter and the sun is lower. Add smog, and a system in Punjab often produces a good deal less in December–January than in April–June. Expect a noticeable drop, not a failure. Adjusting the tilt and keeping the panels clean helps.
Yes. Panels lose a small percentage of output for every degree they run above 25°C, and on a 45°C day the panels themselves are far hotter than the air. N-type panels lose less to heat. An elevated structure lets air flow under the panels and keeps them cooler. Summer is still the highest-output season because the days are long.
In most of Punjab, about every 1–2 weeks. Clean more often after dust storms and in areas near roads, construction, farms or factories. Use plain water and a soft brush or mop, early in the morning or in the evening when the panels are cool. Never use detergent, a pressure washer or a hard brush, and never walk on the panels.
Tier-1 panels are tested for hail impact and wind and snow load. In storms, the structure and fixings usually matter more than the panel itself. We design the structure, anchoring and row spacing for your site's wind exposure, and that is where cheap installations tend to fail.
Rain does no harm to panels and washes off dust. For lightning and surges, a system needs proper earthing, surge protection devices on the DC and AC sides, and correctly rated breakers. We include all three and test the earthing before handover.
Yes, and often better than running an electric geyser from solar panels. Winter is when panels produce least, and an electric element geyser uses a lot of power.
A solar water heater heats water directly from the sun, and a heat pump water heater typically uses a fraction of an element geyser’s electricity. Both help in a Punjab winter; fog days still need a backup source.
"Tier-1" is a financial ranking of manufacturers, published by BloombergNEF. It is not a quality certificate, but it does indicate a large, established maker. We supply panels from brands including LONGi, JinkoSolar, Canadian Solar, JA Solar and AIKO. See the Products page for the models in stock.
Half-cut: each cell is cut in two. This lowers losses and helps when part of the panel is shaded.
N-type: a newer cell technology that loses less power to heat and ages more slowly than older P-type cells.
Bifacial: the panel also collects light reflected onto its back. It gains the most on elevated structures over light-coloured surfaces.
Most modern panels combine all three.
It depends on the system. We supply inverters from Huawei, Sungrow, Solis, GoodWe, Knox, Luminey, Inverex and Primax. Hybrid models cover homes, and three-phase on-grid models cover larger commercial sites. More important than the brand: the inverter must be sized correctly, approved for the battery you use, and backed by local warranty support.
Check the serial number with the manufacturer, on its website or through its local distributor.
Ask for the flash test report and the original packing list.
Look for consistent labels, frames and junction boxes.
Be cautious of prices far below the market.
We show you each panel's serial number before you pay, and every invoice lists the serial numbers.
Panels, inverters and batteries carry the manufacturer's own warranty, which differs by brand and model. We give you the exact terms for each item in writing with your quote. Our own work is covered separately: a 3-year structure warranty and a 1-year service warranty that includes breaker replacement (project terms apply).
We do. You call us, we diagnose the fault on site or remotely, and we raise the claim with the manufacturer or distributor for you. You don't deal with the brand yourself.
Most panels sold in Pakistan today are N-type TOPCon, which replaced older P-type PERC panels. They lose less power in heat and age more slowly.
Back-contact (BC) panels move all the wiring to the back of the cell, so the front catches more light; LONGi’s Hi-MO X10 is one example we supply. Very large 700 W-class panels exist too, but they are heavier and bigger, so the structure, handling and inverter inputs have to be planned for them.
Sungrow systems are monitored with the iSolarCloud app. The inverter connects to your home Wi-Fi or a network cable through Sungrow's WiNet-S communication module, which comes with the residential inverters.
In the app you see live generation, daily energy, battery level on hybrids, and every fault code with its time. Many models also have a small screen and a coloured light on the inverter itself.
We set up the app and account at handover. Keep your Wi-Fi stable near the inverter so the history does not have gaps.
Use a battery that SOFAR lists as compatible with your exact inverter model. SOFAR's manuals say to make sure the battery is compatible and recommend CAN communication between the battery and the inverter.
Some SOFAR hybrids, such as the HYD-EP, accept both lithium and lead-acid batteries, but lithium needs a working BMS link to charge correctly. A battery with the right voltage is not automatically compatible.
Tell us your inverter model and we will check battery options against the current SOFAR list before quoting.
SOFAR inverters connect to your home Wi-Fi through a logger stick. Depending on the model, you monitor the system in the SolarMAN app or SOFAR's own cloud app.
The app shows live generation, daily energy, battery level on hybrids, and every event code with its time. The inverter screen also keeps an Event List you can read without the app.
We set up the app at handover. Keep the Wi-Fi signal good near the inverter so the history has no gaps.
Growatt inverters connect to your home Wi-Fi through a plug-in Shine Wi-Fi or LAN logger, and you monitor them in the ShinePhone app or on the Growatt web portal.
The app shows live generation, daily energy, battery level on hybrids, and error and warning codes. Many models also show codes on their own screen.
We set up the logger and app at handover. Keep the Wi-Fi signal strong near the inverter so history has no gaps.
Huawei inverters are monitored in the FusionSolar app. Most home models connect through built-in WLAN or a plug-in Smart Dongle to your router.
The app shows generation, consumption with a meter, battery level and every alarm with its ID, severity and cause. Most Huawei home inverters have only LED lights, so the app is where you read alarms.
We set up FusionSolar at handover.
Not always. Optimizers fit under each panel and help when parts of the roof are shaded at different times, or when panels face different directions. On an open, evenly lit roof they add cost with less benefit.
They also add per-panel monitoring and some safety functions. Huawei inverters report optimizer layout problems as alarm 2080 and a failed optimizer as 2081.
We decide on optimizers after looking at shade on your roof during the site survey.
GoodWe systems are monitored in the SEMS+ app or SEMS+ web portal; the SolarGo app is used to set up and read the inverter nearby. Fault and alarm details appear in both, and on the LCD where the model has one.
Most homes connect the inverter to Wi-Fi through GoodWe's communication module.
We set up monitoring at handover.
Use a battery that GoodWe lists as compatible with your exact hybrid model. ES models generally take low-voltage lithium batteries, while ET and other high-voltage hybrids need high-voltage batteries.
A matching voltage alone does not make a battery compatible; the BMS must communicate correctly with the inverter.
We check the pairing against GoodWe's current list before quoting.
Solis S6-EH1P-L hybrids take low-voltage lithium or lead-acid batteries. Lithium needs a CAN link to the battery's BMS and the correct battery brand selected in the inverter; otherwise you get CAN Fail or BatName-FAIL.
Some batteries need a special communication cable from the battery maker. A matching voltage alone does not make a battery compatible.
We check the pairing before quoting.
Solis inverters connect to Wi-Fi through a plug-in data logger and are monitored in the SolisCloud app or portal. Alarms such as NO-Grid or OV-G-V appear in the app and on the inverter screen.
We set up SolisCloud at handover.
Fronus Genki and X3 inverters use the SolaX Cloud app and website (www.solaxcloud.com). The inverter connects through a Wi-Fi dongle to your router.
The inverter also has an Error light: steady red for a fault, blinking red for an alarm.
We set up the app at handover.
Yes, as long as the battery model is supported by your Genki and the battery type is set correctly in the inverter. A wrong setting shows BAT_TYPR_CFG_ERR, and a missing link shows BAT_BMS_COMM_FAULT.
Check compatibility for the exact models; matching voltage alone is not enough.
We confirm pairing before quoting.
On Sineng SN PT inverters: green slow blink is standby, fast blink is self-test, steady green is running, blue is updating, red slow blink means AC disconnected with DC on, and steady red is a fault.
The optional screen or the app shows the alarm number for faults.
Send us a photo of the light and screen if unsure.
Sineng inverters use a plug-in communication module to connect to Wi-Fi, and faults show on the panel or the mobile app as alarm numbers. Some SN PT units have an optional screen.
We set up monitoring at handover and explain the alarm numbers.
SolaX inverters connect through a Wi-Fi or LAN dongle and are monitored in the SolaX Cloud app or at solaxcloud.com. Fault codes such as IE 50 appear in the app and on the LCD.
We set up monitoring at handover.
Several Fronus X-series inverters (such as X1/X3-Genki and X3-MIC/PRO/MEGA/FORTH) use the SolaX Cloud app and SolaX-style fault names, which points to a SolaX platform. Warranty and support are handled through the brand on your nameplate, so keep the Fronus invoice and serial if yours is a Fronus.
Fault articles for either brand are useful, but check the code against your own manual.
Knox's on-grid three-phase brochure states it is made by Aiswei (formerly SMA China) and built on the ASW LT-G2 series, which is Solplanet's range. So Solplanet fault codes such as E34 and E38 apply.
Warranty runs through Knox's Pakistan distributor, so keep your Knox invoice and serial.
Solplanet inverters connect over Wi-Fi (4G and RS485 are options on some models) and show event messages in the Solplanet monitoring app. A red LED on the inverter means an error.
We set up monitoring at handover.
Very little. Solplanet recommends keeping the heat sink clear and cleaning it with compressed air or a soft brush, cycling the DC switch on and off a few times once a year, and checking cables for visible damage. Larger LT models have a fan that may need cleaning.
Only clean after the inverter is safely off and cool; ask us if unsure.
SAJ inverters are monitored in the elekeeper app (formerly eSAJ Home), nearby over Bluetooth or remotely through a Wi-Fi, 4G or Ethernet module.
We set up the app and grid code at handover.
SAJ H2 comes in high-voltage and low-voltage (LV battery) versions, so the battery must match the version and be on SAJ's supported list. The BMS must start correctly; code 55 means it has not.
A matching voltage alone does not make a battery compatible. We check pairing before quoting.
The SAJ M2 microinverter works panel by panel, which helps on small or shaded roofs and gives per-panel monitoring. It is an on-grid product, so it stops during load-shedding.
For bigger homes, a string inverter is usually better value.
We advise after a roof survey.
A small project usually takes about a week, depending on payment, equipment stock and site conditions. Elevated or custom structures and commercial jobs take longer. We confirm the timeline after the site survey.
A modern panel covers about 2.5–2.7 m² (roughly 27–29 sq ft). Allow for row spacing to avoid self-shading, walkways for cleaning, and water tanks. A useful guide is roughly 70–100 sq ft of roof per kW. We measure your roof at the survey.
L2 and L3 are standard rooftop frames that hold two or three panels per structure.
An elevated structure is raised high enough to use the space underneath for parking, a courtyard or a shed, and it keeps the panels cooler.
The right choice depends on row spacing, shading and how you use your roof.
Not when it is done properly. We fix the structure onto footings or base plates and seal every point where the roof surface is penetrated. We check the roof's condition at the survey, before any work starts.
In Punjab, panels should face south, tilted at about 20–30°. A lower tilt favours summer and a steeper one favours winter. East–west layouts also work where roof space or shading requires them. We set the angle for your roof and your usage.
Usually yes, if the inverter has spare capacity and inputs, and your sanctioned load allows it. Tell us at the start if you plan to expand, so we size the inverter and cabling for it. If you are on a grandfathered net metering agreement, talk to us first.
Sometimes, but often it isn't worth it. An old UPS isn't designed for solar charging, and old tubular batteries are usually near the end of their life. Mixing old batteries with new ones, or using a battery the inverter isn't approved for, causes problems. We check what you have and tell you honestly.
Often yes, with permission. In a rented house the owner has to agree to the installation, and any DISCO application goes in the name on the electricity bill, so the owner needs to be involved.
In a flat the roof is usually shared, so you need the building or society’s approval and your own share of roof space. Where panels are not possible, a battery backup system without panels can still cover load shedding.
At the survey we measure the roof, check shading through the year, look at the roof’s condition and access, and note your electrical board, earthing, meter and connection type.
We go through your bills and the appliances you want on backup, then agree where the inverter and battery will go. From that we prepare the design and a final itemised quote. Surveys are normally free.
Yes. A solar pump system uses a pump inverter (VFD) that runs the motor directly from the panels during the day, with no batteries needed. Many farms in Punjab have cut their diesel or grid costs this way.
It depends on three things: the pump's horsepower, the depth of the water table or bore, and how much water your crops need each day. Send us the motor HP, the bore depth and your acreage. We will size the panels and the inverter, and design an elevated structure if one is needed.
Yes. We design, supply and install commercial and industrial systems from about 6 kW to megawatt scale, including three-phase on-grid and hybrid systems. We provide load analysis, structure design and commissioning records.
For a three-phase home or small business on net billing, the Sungrow SG-RT on-grid range is the usual choice; the SH-RT hybrid adds battery backup. For larger commercial and factory roofs, Sungrow's SG-CX range covers bigger sizes, and the SG-HX range is built for very large projects.
The right size depends on your sanctioned load, roof area and how much you use in the daytime. Three-phase inverters also need a reasonably balanced supply, so we check all three phases at survey.
Share your bills and sanctioned load and we will recommend a model and size in a written quote.
For three-phase net billing, GoodWe's SDT range is the usual choice, with SMT, MT and larger HT/GT ranges for bigger commercial roofs. For three-phase with battery backup, the ET hybrid range is used.
Three-phase inverters need all three phases present and in the right order; the inverter reports phase loss, imbalance or sequence faults otherwise.

Yes. The X3-MIC, X3-PRO, X3-MEGA and X3-FORTH are three-phase on-grid ranges for net billing, from smaller shops up to larger commercial roofs. X3-MIC G2 models have up to 12 MPPTs on the larger sizes and IP66 protection.
They stop during load-shedding, like all on-grid inverters.

Yes. The SN PT range covers roughly 3 to 12 kW three-phase on-grid models with two MPPTs and a wide input range, suiting three-phase homes and small businesses on net billing.
It needs all three phases present and in the correct order; otherwise it reports Phase reversed (Alarm 6) or grid alarms.

Yes. The X3-MEGA G2 is a three-phase on-grid range for commercial roofs, with multiple MPPTs and export control. It needs all three phases present and a reliable earth.

One team looks after your system from the survey onwards. After-sales service covers fault diagnosis, repairs, warranty claims, cleaning advice and technical support by phone or WhatsApp. The first year of service is free: there are no visit charges, and breakers and other equipment are under warranty for that year.
Yes. Most inverters we install connect over Wi-Fi to the manufacturer's app, which shows production, use, battery level and grid import and export. We set the app up for you at handover.
The app also keeps your inverter's alarm history. In apps such as SolisCloud you can turn on push notifications or email alerts, so you hear about a fault the same day instead of at bill time.
Your installer can see deeper checks in the same platform, such as string-by-string comparisons and IV-curve scans on supported inverters. These help find a weak string without a site visit.
Monitoring needs the inverter's Wi-Fi dongle on a 2.4 GHz home network. SIM-based loggers are not available in Pakistan.
A correctly installed system is designed to operate safely. That means proper earthing, breakers and surge protection, cables in conduit, the equipment mounted out of children's reach, and a clear isolation point. Keep children off the roof and away from the inverter and battery. Only trained people should work on the system.
We have offices in Faisalabad and Lahore. We regularly work in Samundari, Gojra, Khurrianwala and Shahkot, and we take jobs all over Punjab. Message us your location and we will confirm.
Message us on WhatsApp at 0336 666 4321 with your name, city, your last 12 months of electricity bills and a few photos of your roof. You can also use the site-visit form. We reply with an initial estimate, then book a survey for a final quote.
A photo of one electricity bill tells us more than an hour of questions. We reply with a system size and a price range before anyone visits the site.
Ask us on WhatsApp. We answer you directly, then add it here for the next person.
