3. Monitor the INVERT (Green kW) LED to confirm which mode the inverter is in:
• LED is off—Invert mode is disabled. The inverter/charger is not powering
the AC loads. However, if qualified AC is present from the utility or a
generator, it is passed through to the loads.
•

on the display—The inverter/charger is in the Search mode and is
looking for an AC load greater than the Search Watts setting
(default = 25 watts).
• LED is on—The inverter/charger is on. The inverter is operating and is
able to provide power to the AC loads. This is the default mode on initial
power-up once the unit is taken out of Standby mode.
If the inverter is not operating or the INVERT LED (kW) does not turn on, check
all connections. Check the inverter’s DC voltage on the positive (+) and
negative (–) terminals. Check the Fault LED. If the Fault LED is on, check for a
fault code on the information panel. Correct the reported fault if possible and
clear the fault. If the DC voltage is low, the battery bank needs to be charged
externally. Charge the battery bank and restart the functional test.
AC Voltage Check
To perform an AC voltage check:
1. With the inverter on (INVERT [green, kW] LED is on and steady), verify the AC
voltage at the AC Loads block terminal L-Load to N-Load.
2. Verify that neutral is bonded to ground in the system by measuring the live
and neutral voltages relative to ground. Neutral-to-ground should equal zero
(0) volts.
3. After confirming the correct AC voltage, turn on your AC output breaker and
place a load on the inverter (plug in a light or other load to an outlet the
inverter is powering).
4. Confirm that the AC load just applied works properly.
