App, meter and bill problems
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.
Solar app offline after router change
The app shows your plant as offline, but the system is still generating.
Exported units not matching the bill
Your app says you exported a certain number of units, but the DISCO bill credits fewer, or none.
Waiting for a LESCO green meter
In September 2026 LESCO was reported to have paused issuing bidirectional (green) meters because of a shortage.
LESCO net billing instead of net metering
Some LESCO consumers who applied and signed under the net metering policy received bills calculated under net billing instead.
FESCO solar files above 25 kW
Commercial and industrial net billing applications above 25 kW go through extra technical review before approval.
Factory solar: self-use vs export
Under net billing, exported units are paid at a much lower rate than you pay for grid units.
Solar app shows negative consumption
A negative consumption figure can make it appear that the house is generating electricity.
Solar app figures don’t add up
Power-flow screens combine several quantities.
Recover solar history after internet outage
An empty section in a production graph can mean missing monitoring data rather than lost generation.
Solar production shown at the wrong time
A chart showing daytime generation at an unexpected hour may have a time-setting or reporting issue.
Inverter or logger already registered
An “already registered” or “already bound” message usually calls for an account-association check before another plant is created.
Recover your solar monitoring account
Losing access to a monitoring account can make a working solar system difficult to oversee.
Change the installer on your solar app
Changing the service provider should include a clear decision about monitoring access.
Solar app lagging behind the inverter
The inverter screen and a cloud app do not necessarily refresh at the same moment.
No fault notification from your solar app
An alarm in the system history and a notification on your phone are different parts of monitoring.
Old or duplicate devices in the solar app
A replaced inverter or logger may still appear in a monitoring account.
Electricity bill still high after solar
A high bill needs to be separated into two questions: how much electricity the property used from the utility, and how that usage and other charges were billed.
Importing from the grid on a sunny day
Sunlight does not guarantee that solar output covers every load at every moment.
Electricity meter display gone blank
A blank utility-meter display should be reported to the electricity provider.
Readings to keep when a meter is replaced
A meter replacement can interrupt the continuity of the visible readings.
Estimated bill despite solar monitoring
Solar monitoring and utility billing serve different purposes.
Arrears and adjustments after solar
The payable amount on an electricity bill may include more than the current period’s electricity charges.
Factory maximum-demand charge not falling
Solar can reduce purchased energy without reducing every demand-related charge.
Factory power factor worse after solar
A change in power factor needs a separate assessment from solar generation.
Checking a shared solar bill statement
A shared electricity statement should make clear what was measured, which period was covered and how the agreed allocation was applied.
Zero-export system showing export
A brief export reading and sustained export require different investigations.
Giving a technician remote access
Remote access can help a service team review operating records and, where supported, perform authorised work.
