Inverter Status Remedy
1 POV
The solar cell voltage
is higher than the
specified voltage.
Check the solar cell voltage and restart.
Contact for service if restart fails.
2 PUV
The solar cell voltage
is lower than the
specified voltage.
Check the solar cell voltage and restart.
This can occur when the sun sets or it is
cloudy. Check for restart on the next day.
3 ULF Utility Line Fault.
The inverter automatically restarts when
utility grid is normalized.
4 IOC
The inverter current is
higher than the
specified value.
The inverter automatically restarts within
one minute after the over current factor
such as short circuit is removed. Contact
for service if restart fails.
5 ASY
The phases of the
inverter and the
phases of utility grid
are not synchronized.
The inverter automatically restarts when
utility grid is synchronized.
6 LUV
The system voltage is
lower than the
specified value.
The inverter automatically restarts when
utility grid is normalized.
7 LOV
The system voltage is
higher than the
specified value.
The inverter automatically restarts when
utility grid is normalized.
8 COC
Over current in the
converter inside the
inverter.
Check the inverter and restart the
system.
9 LOF
Over frequency of the
system.
The inverter automatically restarts when
utility grid is normalized.
10 LUF
Under frequency of
the system.
The inverter automatically restarts when
utility grid is normalized.
11
Ground
Fault!
Utility grid ground
fault.
Check the system. The inverter
automatically restarts when the ground
fault is removed.
