Priority Red LED LED Signal Status
Flash 1
One of the alarms as follows:
1) EEPROM Fault;
Inverter module cannot operate in
parallel mode system, however, it can
work in single mode system
2) Fan Fault
Fan failed in operation
Flash 4
One of the alarms as follows:
1) Internal DC Bus Over
/Under/ Unbalance/soft start fail;
The inverter will shutdown.
2) Over Temperature.
The inverter will shut down.
In both cases Recycle the power or
remove and reinsert the module to
restart.

High
Solid
One of the alarms as follows:
1) Input reverse polarity;
The DC input voltage polarity is
reversed.
2) Inverter output short circuit;
When a short circuit occurs the
inverter will shut down.
3) Abnormal output voltage;
The inverter will shut down when
output voltage is out of operating
voltage range.
4)Negative Power Protection
The inverter will shut down.
5) Overload fault.
When the time of overload exceeds the
defined time, the inverter will shut
down.
In all cases recycle the power or remove
and reinsert the module to restart.
Notes:
Power On Sequence:
When the inverter is in “Power On” mode, the green led and the yellow LED are blink synchronously.
Overload and overload fault:
When the overload fault alarm occurs the yellow and red LEDs turn on at the same time.
When an overload alarm occurs only the yellow LED turns on.
Priority:
If more than one warning exists at the same time, then the LED will display the highest priority condition.
