Error Condition Possible Cause Recommendation
AC output exists
with yellow LED
flashing.
Input voltage is out of
operating range.
Ensure input voltage is between 45V and 58V.
Check if the battery or dc source is connected.
AC output exists
with yellow LED
on
Load is over 100% but below
125%.
Reduce the load to below 100% of the total
power rating.
Failure of EEPROM Reboot the inverter system by switching the
input power source on and off.
Inverter
continuously
delivers power,
with red LED
flashing slowly.
Fan failure. If the fan is blocked, remove the cause.
If the fan fails to operate, return the inverter for
service.
Inverter Module LED display status (Low to High Priority)
LED LED Signal Status
Continuous
Normal operation.
Slow Flash (1Hz)
Inverter is communicating.
Green
Short Slow Flash
(1Hz)
Either:
1) Power On. Refer to note.
2) Shut down remotely.
Short Slow Flash
(1Hz)
Power On. Details refer to note.
Continuous
Over Load (Load > 100%)
Fast Flash (4Hz)
DC input abnormal
(Vin<=45V or Vin>=58 V)
Yellow
Short Fast Flash
(4Hz)
Inverter shut down due to low/high
input (Vin<=VLVSD or
Vin>=VHVSD)
Slow Flash (1Hz)
Either:
1) EEPROM Fault. The inverter can
not operate in parallel mode system,
however, it can work in single mode
system
2) Inverter Fan Fault. Fan fails to
operate.
Fast Flash (4Hz)
Either:
1) Internal DC Bus Over/Under/
Unbalance/soft start fail. The
inverter will shutdown. It cannot
restart automatically.
2) Temperature High. The inverter
will shut down. It cannot restart
automatically.
Red
Continuous
Either:
