State
Error code
Description
Causes
Initialization
Waiting
Initial PV voltage is between Min.DC input
voltage and start-up DC input voltage of
the inverter.
Checking
The inverter is checking feeding conditions
after initial PV voltage exceeds start-up
DC input voltage of the inverter.
Reconnect
The inverter is checking feeding conditions
after the last fault has been solved.
Normal
Normal
The inverter is operating normally.
Fault
1
SPI Fault
Communication between the master and
slave CPU has failed.
2

Output current sensor is abnormal.
9
GFCI Fault
GFCI detection circuit is abnormal.
10
Device Fault
Unknown Error
11
M-S version
unmatched

master and slave CPU.
33
Fac Fault
The grid frequency lies outside the
permitted range.
34
Vac Fault
