Operating conditions In English Description Feeding current Iac = x.xA Feeding current amount in xx.x A
PV array voltage Vdc = xxx.x V Input voltage from PV array, xxx.x VDC
Daily Energy Etoday=xxx.xxKW
h The accumulated kWh of that day
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
