Troubleshooting · 11 guides
No backup during load-shedding
Each guide says what you will see, why it happens, what you can safely check yourself and when to call an engineer. Never open the DC side yourself: solar strings stay live whenever there is daylight.
On-grid inverter stops in load-shedding
Your panels are in sunlight, but the inverter stops supplying electricity as soon as the grid goes off.
Hybrid inverter on but no backup power
The inverter screen is on, but the lights, fans or other appliances connected for backup have stopped.
Solar backup load division
Load division means deciding which appliances receive backup during load-shedding and arranging their circuits to match.
PCs and routers restart on solar changeover
A computer shuts down or the Wi-Fi router reboots when load-shedding starts, even though other appliances keep running.
Solar backup stops when clouds pass
Cloud cover can reduce solar output quickly.
Hybrid won’t restart after a flat battery
Backup may stop after a long power cut or overnight discharge.
UPS beeping or switching on solar backup
A UPS connected to a solar-backed socket may beep, click repeatedly, refuse to charge or continue using its own battery.
Appliances work on grid, not on solar backup
An AC, pump, refrigerator or machine may run normally on grid electricity but fail to start during load-shedding.
Lights flicker on battery backup
Lights may appear steady on grid electricity but flicker once the property runs on battery backup.
Daytime backup from a hybrid without batteries
Some hybrid inverters can provide solar-only backup, but support must be confirmed for the exact model, firmware and installation.
Inverter Bypass Mode: Why Your Inverter Is Stuck in Line Mode
Inverter bypass mode means the inverter is passing grid (WAPDA) power straight through to your loads instead of running them from solar or the battery.
