System Fault
Isolation failure Isolation fault
Earth fault of the PV-panels or failure of
surge voltage protection
GFCI active Ground I fault
Leakage current detected from ground
conductor is too high
Grid failure Grid fault
Grid measured data is beyond the
specification (voltage & frequency)
No utility No Utility Utility is not available
Input voltage too high PV over voltage
Input voltage is higher than the maximum
input voltage
Inverter Fault
Consistent failure Consistent Fault
The readings of 2 microprocessors are not
consistent. It could be caused by CPU
and/or other circuit do not function well.
Temperature too high Over temperature
The internal temperature of inverter is
higher than normal value
Output relay failure Relay Failure
The relay between inverter and grid is not
functional
Output DC injection too high DC INJ High
Output DC injection is higher than
expected
EEPROM problem EEPROM Failure EEPROM inside has data access problem
Communication failure
between microprocessors
SCI Failure
The communication between MCU inside
is abnormal
