※ 9.2 Inverter Maintenance
Risk of inverter damage or personal injury due to incorrect service!
Always keep in mind that the inverter is powered by three sources: PV
strings, battery and utility grid.
Before any service work, observe the following procedure.
①
Shut off the inverter through the APP or the button on the display first.
② Disconnect the breakers on the grid and load side.
③
Turn off the battery switch, and disconnect the DC breaker on the
battery side (if any).
④
Wait 30 seconds and then turn the inverter DC switch to the “OFF”
position. At this time, there is remaining power in the inverter capacitor.
Wait for 10 minutes until the inverter is completely de-energized before
operating.
⑤
Verify that there is no voltage or current before pulling any connector.
DANGER
Keep non-qualified persons away!
A temporary warning sign or barrier must be posted to keep non-
qualified persons away while performing electrical connection and
service work.
CAUTION
Restart the inverter only after removing the fault that impairs safety
performance.
Never arbitrarily replace any internal components.
For any maintenance support, please contact Solinteg. Otherwise,
Solinteg shall not be held liable for any damage caused.
NOTICE
Servicing of the device in accordance with the manual should never
be undertaken in the absence of proper tools, test equipment or the
