2 .5 Test ing t he I nve r t er
Before proceeding, fi rst test whether the inverter was successfully installed.
Use the functional test below to test the inverter, and then perform the GFCI
test that follows to ensure the protection device is functioning properly.
2 .5 .1 I nve rt e r Funct ional Test
After all electrical connections to the inverter and batteries have been
completed, plug a small AC load (e.g., 40W light bulb or small appliance)
into the GFCI’s outlet, and then follow these steps to test the installation and
the inverter’s operation.
1. Press and hold the Power/ Select button until a beep sound is heard
(about 1 second). The St atus light turns on.
2. Check that the digital display alternately shows the inverter’s measured
battery voltage and output power.
3. Check that the AC load is on (i.e., the bulb lights).
N ot e: I f the bulb does not light, the GFCI m ay have t ripped. Reset t he GFCI
by pressing the RESET but t on.
If the inverter passes all steps, it is functioning properly and ready for use.
If the inverter fails any steps, refer to Section 4.0 Troubleshooting.
2 .5 .2 GFCI Funct ion Test
Use the steps below to periodically test the GFCI to ensure proper functioning.
1. Turn the inverter on.
2. Plug a small AC load (e.g., 40W light bulb) into the GFCI’s outlet.
3. Check that the AC load is on (i.e., the bulb lights).
4. Press the GFCI’s TEST button. The GFCI’s RESET button should pop out,
and the power should shut off (light bulb goes out).
N ot e: I f the bulb rem ains lit or t he RESET but t on does not pop out , the GFCI
m ay not be functioning properly or the load sensing funct ion m ay need t o be
disabled. See Section 3.2.1.
5. Press the RESET button. The AC load (light bulb) should come back on.
