Functional Test

After all electrical connections
(using a sub-panel)
installation and the inverter's operation.
1. Check the battery voltage and polarity before connecting the batteries
to the inverter. Use a multimeter to verify 10 to 15 VDC at the batteries'
positive and negative terminals.
2. Apply battery power to the inverter by switching the DC disconnect on
(or close the DC circuit-breaker). The inverter will remain off, but the
green status indicator on the front of the inverter will quickly blink once to
indicate that DC power has been connected and is ready to be turned on.
3. Prior to turning on the inverter, make sure all connected loads (e.g.,
appliances) are switched off or disconnected from the AC outlets.
4. a. If a remote switch is connected, press the ON/OFF switch to turn the
inverter on.
b. If there is not a remote switch connected, lightly press and release the
inverter's ON/OFF power switch—located on the top of the inverter—to
turn the inverter on.
Verify the inverter's status indicator is blinking—indicating the inverter
is providing AC power.
5. Check the output voltage of the inverter by connecting a multimeter to the
outlets powered by the inverter. Verify the voltage is 120 VAC +/- 5 VAC.
6. Turn on or connect a load to the outlets and verify it comes on. Continue
to keep the load connected and turned on.
7. Press the remote ON/OFF switch to turn the inverter off. If the remote is
not used, press and release the inverter's ON/OFF power switch to turn
the inverter off. The inverter's status indicator and the connected load
should go off.
8. Apply AC power to the inverter's AC input. After the AC input power
is qualifi ed (approximately 15 seconds), the incoming AC power will
transfer through the inverter to the inverter's AC output and power the
connected load. Verify the inverter's status indicator and the connected
load comes on.
9. Even though the connected load is on, the inverter is currently disabled/
off. Press the remote's ON/OFF switch (or press and release the ON/OFF
power switch on the inverter) to enable/turn on the inverter.
10. Disconnect the incoming AC power to the inverter. Verify the connected
load remains on, but now is powered by the inverter.
If the inverter passes all the steps, the inverter is ready for use.
If the inverter fails any of the steps, refer to the Troubleshooting section.
