Fault code 03
Battery is over-charged. Return to repair center.
The battery voltage is too high.
Check if spec and
quantity of batteries are
meet requirements.
Fault code 01 Fan fault Replace the fan.
Fault code 06/58
Output abnormal (Inverter voltage
below than 190Vac or is higher
than 260Vac)
1. Reduce the connected
load.
2. Return to repair
center
Fault code
08/09/53/57
Internal components failed. Return to repair center.
Fault code 51 Over current or surge.
Restart the unit, if the
error happens again,
please return to repair
center.
Fault code 52 Bus voltage is too low.
Fault code 55 Output voltage is unbalanced.
Fault code 56
Battery is not connected well or
fuse is burnt.
If the battery is
connected well, please
return to repair center.
6.4 Quick start
Before any detail check of the system, please check the components listed as follow table.
NOTE: It is important to check the capacitor’s voltage on the board lower than the safety voltage before
any check action.
