1E Igrid unbalance
During grid connection, the difference of 3-
phase current is relatively large.
Wait for the inverter to return to normal.
If the fault occurs repeatedly, please
contact Sinexcel Electric Customer Service
Center.
1F Over-temp 2
The radiator temperature in inverter power
module is too high.
1. Check if the fan is working
2. Clean the vents
If the fault occurs repeatedly, please
contact Sinexcel Electric Customer Service
Center.
20 Inv Output O/L/T
The output overload and timeout of the
inverter exceed the limit.
Reduce the load.
If the fault persists, please contact Sinexcel
Electric Customer Service Center.
21 AC continuous OV Grid voltage abnormal oscillation
1. Check whether the grid voltage
amplitude is stable within the limit value
2. Check if the continuous overvoltage limit
value setting is reasonable
