The use of a 10 watt or greater light bulb ensures that the loads within the home or building
are protected and not at risk of damage or failure during this test procedure.
Check the AC output voltage of the Energizr by connecting an AC voltmeter to the LOADS subpanel. Verify the correct output voltages. If 120 volts AC are measured on both Phases to
Neutral and/or Ground, and 240 volts AC are measured between both Phases of the Energizr
output, proceed to Step 7.
7. Turn ON the GRID AC voltage to the Energizr. After the GRID AC voltage to the Energizr is
qualified (approximately 60-70 seconds), the Energizer will stop inverting power from the
batteries, the incoming GRID AC voltage will transfer through the Energizr to the LOADS subpanel, and the 10 watt or greater light bulb will now be powered by the GRID and not the
batteries. The green SYSTEM LED on the front of the Energizr will now be turned ON.
INFO: At this point, the red CHARGING LED on the front of the Energizr may or may
not be lit. The state of charge of the batteries will dictate whether or not the charger is
turned on and charging the batteries. The red CHARGING LED may be solid or blinking,
depending on the type of charging status the charger is in. See Section 3.8 LED Operation.
Check the AC output voltage of the Energizer by connecting an AC voltmeter to the LOADS subpanel. Verify the correct output voltages. If 120 volts AC are measured on both Phases to
Neutral and/or Ground, and 240 volts AC are measured between both Phases of the Energizer
output, proceed to Step 8.
8. With the 10 watt or greater light bulb turned on, turn OFF the GRID AC voltage to the
Energizr. The Energizr will switch to the batteries and supply inverted power to the LOADS subpanel. Verify that the 10 watt or greater light bulb remains on. Once again, check the AC
output voltage of the Energizr by connecting an AC voltmeter to the LOADS sub-panel. Verify
the correct output voltages. If 120 volts are measured on both Phases to Neutral and/or
Ground, and 240 volts are measured between both Phases of the Energizr output, proceed to
Step 9.
9. Turn ON the GRID AC voltage to the Energizr and wait for the Energizr to connect to the grid
(approximately 60-70 seconds). The green SYSTEM LED and the blue RENEWABLES LED on the
front of the Energizr will be lit.
With the RENEWABLES system (string inverter or micro-inverters) turned OFF, check the
RENEWABLES AC output voltage of the Energizer at the connection between the Energizer and
the RENEWABLES system (disconnect or circuit breaker). Verify the correct output voltages. If
120 volts AC are measured on both Phases to Neutral and/or Ground, and 240 volts AC are
measured between both Phases of the Energizr output, proceed to Step 10.
