Installation
Important: If required by code, have the installation inspected by an electrical inspector.
2.9 Functional Test
After all electrical connections to the inverter, batteries, AC source, and sub-panel have been
completed, follow these steps to test the installation and the inverter operation.
CAUTION: Use a multimeter to verify the correct DC voltage for your particular inverter
model (i.e., 12-volt battery bank for a 12-volt inverter) and to ensure the polarity of the
battery voltage is correct (battery positive connected to the inverter positive terminal
and battery negative connected to the 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 the inverter 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 any AC outlets powered by the inverter.
3. Lightly press and release the inverter’s ON/OFF switch to turn the inverter on. Verify the
inverter’s status indicator is blinking—indicating the inverter is on.
4. Connect a 10-25 watt light bulb 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, when the Search mode is
turned off with a remote display (ME-RC50 or ME-ARC). 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. Check the AC output voltage of the inverter by connecting an AC voltmeter to the output
terminals (see Figure 2-17) and verify the correct output voltages.
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 (approx. 15
secs), the incoming AC power transfers through the inverter to the inverter’s AC output and
powers the light bulb. Verify that the inverter’s status indicator and the light bulb come 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 previous steps, the inverter is ready for use. If the inverter fails any
of the steps, refer to the Troubleshooting section.
