5.3 Troubleshooting
There are mainly three fault alert statuses: Warn,
Protect and Fault. When there is a “Warn”, the system only
reminds customers of the problem while it doesn’t change
the operation mode. When there is a “Protect”, the system
will turn into fault mode and come back to normal when the
“Protect” disappears. When there is a “Fault”, the system will
stop working and remain standby until resetting the system
or repair the inverter to eliminate the fault.
Two ways of system reset are listed as follows:
1. Turn off the AC circuit breaker, wait for 5 seconds and
turn on the AC circuit breaker again to recharge the system
control unit. If the system check is passed, the inverter will
turn into normal operation mode.
