Possible cause Action
W001 Sun low
Insufficient radiation. Number of
modules / string too small.
Incorect wiring
No action… waiting for Sun
Configuration and wiring verification
W002 Input undervoltage
Input voltage to low
As W001
No action… waiting for Sun
Configuration and wiring verification
W003 Grid Fail
Grid voltage out of limit
Grid voltage, frequency, inverter settings and AC
wiring verificaion
W004 Grid Overvoltage
W005 Grid Undervoltage
W006 Grid Overfrequency
Grid frquency out of limit
W007 Grid Underfrequency
W008 Z Grid out of Range Grid impedance out of limit Wiring and gridimpedance parametrs verification
W010 Fan Fail Fan failure
Check if the fan is blocked because dirt, failure may
cause derrating -> replace
W011 Bulk undervoltage Input voltage to low Configuration verification
W012 Clock Battery low
Low battery (device stays on the
grid)
Battery replace
W013 Clock Failure
Problem with the time (unit
remains on the grid)
Set time. If the problem shows up again -> Swap
