Lack of input power
Inverter self-diagnosis
Load exceeds 125%
1. Input wiring is reverse
polarity.
2. Internal fault
3. Inverter output is shorted
1. Inverter fails to soft start
2. Inverter temperature is
above the temperature limit.
Input voltage is out of
operating range.

Recommendation
1. Check if input cables are all firmly connected
to power source.
2. Check if power source is switched on, or is
low in power.
Inverter self-diagnosis takes a few seconds. LED
then turns to a solid green.
Reduce the load to below 105% of the total
power rating.
Check input cable polarity (positive to positive,
negative to negative).
Reboot the inverter by switching the input
power source on and off.
If the inverter fails to operate, return the inverter
for service.
Turn off the input power source to remove all
short circuits.
Reboot the inverter by switching the input
power source on and off.
Leave inverter idle to cool down for few
minutes.
Ensure input voltage is between 45V and 58V.
Check if the dc source is connected.
Reduce the load to below 105% of the total
power rating.
Reboot the inverter system by switching the
input power source on and off.
If the fan is blocked, remove the cause.
If the fan fails to operate, return the inverter for
service.
