Functional Test

After all electrical connections
completed; follow these steps to test the installation and the inverter's operation.
CAUTION: Use a multimeter to verify the correct DC voltage for your particular inverter
model (i.e., 24-volt battery bank for a 24-volt inverter) and to ensure the polarity of
the battery voltage is correct (battery positive connected to inverter positive terminal
and battery negative connected to inverter negative terminal).
1. Apply battery power to the inverter by closing 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.
2. Prior to turning on the inverter, make sure all AC loads (e.g., appliances) are NOT connected
to the inverter's output or to any AC outlets powered by the inverter.
3. Lightly press and release the inverter's ON/OFF switch to turn on the inverter. Verify the
inverter's status indicator is blinking—indicating the inverter is on.
4. Connect a light bulb (10-25 watts) to the inverter output and verify it comes on and shines normally.
DO NOT connect anything larger than a 25-watt light bulb until all wiring and voltages are confi rmed
to be correct.
Info: The inverter's AC output voltage will not be correct until a load greater than 5
watts (default setting) is connected to the inverter; or, the Search mode is turned off
with a remote display (ME-RC, ME-ARC, ME-RTR). A 10-25 watt light bulb is used as
it is a suffi cient load to bring the inverter out of Search mode and up to full voltage.
5. Verify the AC output voltage of the inverter by connecting an AC voltmeter to the output
terminals (see Figure 2-19).
6. 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.
7. 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 light bulb. Verify the inverter's status indicator and the light bulb comes on.
8. Even though the light bulb is on, the inverter is currently disabled (off). Press and release the
ON/OFF switch on the inverter to enable (turn on) the inverter.
9. Disconnect the incoming AC power to the inverter. Verify the light bulb remains on and is now
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.
