Functional Test
After all electrical connections
to the inverter, batteries, AC
source, and loads (using a sub-panel)
have been completed; follow
these steps to test the installation and the inverter 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 (i.e.
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 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 true RMS
multimeter to the outlets powered by the inverter. Verify the voltage
is 120 VAC +/- 5 VAC. If not using a true RMS meter, the output AC
voltage could indicate from 90 to 130 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 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 qualified (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 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.
