Test installation
WARNING
Shock hazard –
AC power from a utility/grid will still pass through the inverter to the AC output even with the inverter turned
OFF. Turning the inverter OFF with the button will not disconnect DC or AC input power, this must be done manually.

Prior to system testing assure that the DC fuse is installed and the optional switch is closed. Verify that a minimum of
12.3V is present at the Inverter DC terminals. For best results assure batteries are fully charged.
Prior to use:
1. Verify the inverter is inverting DC battery power AND delivering AC power to the outputs.
2. For installations where AC input and output are hardwired to the inverter, verify the inverter transfers from inverter
power to utility/grid power when the utility/grid power is present.
Testing in INVERTER MODE
1. If hardwired, ensure utility/grid power is not present.
2. Press the Power button ≈ 1 second to turn the inverter on. The status LED on the panel will glow yellow and the display
screen will illuminate.
3. Using an appliance within the inverter’s range, plug it into the GFCI on the front of the inverter, or plug it into an AC out-
let hardwired to the inverter.
4. Turn ON the appliance and verify it functions properly.

If the appliance functions as expected, the installation is a success! If it was a hardwire installation, continue reading.
Testing in UTILITY/GRID MODE
1. Using the same appliance from the previous test (must be within power range of inverter), plug it into the GFCI of the
inverter.
2. Connect the utility/grid power source.
int:
H
The inverter will transfer the appliance to utility/grid power. The status LED on the panel will change from yellow to a
flashing yellow for ≈20 sec and then green. If the appliance then functions as expected, the installation is a success!
ote:
N
If the INVERTER button on the inverter is ON, the inverter will automatically supply the appliance(s) with inverted
power from the battery upon the utility/grid power source failing or becoming disconnected. The same will happen if
the utility/grid voltage falls too low (less than ≈ 90Vac).
WARNING
Shock hazard –
When a battery is connected to the DC input (*), utility/grid power will always pass through the inverter to
the AC output even if the inverter is turned OFF.

*Battery needs to be connected properly to the inverter and have a minimum voltage of 11V
STATUS LED Indicator
•
Solid Green - Battery connected is fully charged in AC bypass mode
•
Flashing Green - Charging is in progress in AC bypass mode
•
Flashing Amber - AC input is detected and being qualified in AC bypass mode
•
Solid Amber - Inverter AC output is on in inverter mode
•
Solid Red - Indicateds an error was found. The digital display shows the fault code
