AC Voltage Check
To perform an AC voltage check:
1. With the inverter on (green kW LED is on and steady), verify the AC voltage at
AC Loads block terminal L1-Load to N-Load.
2. Verify that neutral is bonded to ground in the system by measuring the hot
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 that was just turned on is working properly.
Confirming Battery Charger Operation
To confirm battery charger operation:
1. Apply AC from grid or generator. LEDs will blink while the power source is
qualified.
2. Check LEDs (AC1 or AC2) on the front panel. One of them must be ON for
the unit to charge.
3. Check the amp (A) LED. If the A LED is ON, the unit is charging and the
battery current is displayed on the inverter information panel.
Note: This test requires the use of a voltmeter.
