Disconnect the inverter from the grid first, then the PV strings and the battery
before any maintenance work.
Lethal voltage still exists in the inverter. Please wait at least 10 minutes and then
perform maintenance work.
There is a button cell on the inner PCB board. Contact SUNGROW for replacement when
the relevant fault alarm occurs.
Check the fastener, appearance, voltage, and resistance quarterly and annually.
