AC UNDER VOLTAGE FAULT
To Identify an AC Under Voltage Fault
If the inverter displays an AC Under Voltage fault and all the voltages going
into the inverter are within the tolerances provided in the specifications, continue
with the following troubleshooting tips.
1. Check the main branch circuit breaker.
a. If the breaker is not tripped:
Check the small fuses located on the AC distribution PCB (there are nine in
three sets of three). If one or more of these fuses have opened, replace them
with like parts (600 VAC, 10 A or 20 A as required)
2. If any of the fuses are open, visually inspect the wiring. Look for the following:
a. Frayed wires or carbon marks indicating a short
b. Burned traces on the PCBs
If any of these conditions are present, DO NOT START THE INVERTER.
Contact AE Solar Energy Technical Support for replacement parts or service.
IDENTIFYING A GROUND FAULT
The inverter is equipped with a Ground Fault Detector Interrupter (GFDI). The
purpose of the GFDI is to detect a ground fault (unintended current flow from the
solar panels to earth ground) and in this event, disable the inverter.
WARNING:
For the GFDI circuit to function as designed, the solar array safety ground
must not be connected to the PV array positive or negative leads. Bonding
the safety ground to the grounded leg of the array anywhere but through the
inverter will cause the GFDI circuit to be bypassed. This would defeat the
operation of the GFDI and potentially create an unsafe operating condition.
