Solis inverter shows OV-G-V (grid overvoltage)

Short answer

OV-G-V01 to OV-G-V05 mean the grid voltage at the Solis inverter went above its limit, either steadily or as a short spike. The inverter stops and reconnects when voltage is normal. Repeated afternoon trips usually point to high local grid voltage or a long AC cable.

What you will see

Why it happens

Many homes exporting together raise transformer voltage; a thin or long AC cable adds to it.

What you can check yourself

Note the times
Ask neighbours if theirs stop too
Check the AC breaker is fully ON

What not to do

Do not change grid settings without FESCO or LESCO consent

When to call us

Measure voltage at meter and inverter
Check AC cable size and joints
Prepare readings for the DISCO

Midday voltage

High midday voltage is common on busy FESCO and LESCO transformers. We take readings for your DISCO complaint.
