Quick Evaluation Before Installation
•
This section provides you with basic information about the inverter and
how to check its performance before installation.
Be Sure to Have on Hand:
A 12 volt DC power source (such as a vehicle battery).
The power source must provide between 11 and
15 volts DC and be able to supply enough current
to run the test load. As a rough guide, divide the
wattage of the test load by 10 to get the current
(in amperes) the power source must deliver.
The provided 2 ft. direct-to-battery 12 gauge cable.
Only use the cable provided with your inverter.
A test load that can be plugged into the AC
receptacle on the inverter for short term
testing at a low power level.

To Check Your Inverter’s Performance Before Installation:
1. Turn the inverter Off (see page 13 for details).
If the power source is a DC power supply,
switch it Off as well.
2. Connect cables to Power Input Terminals
(see page 8 for details).
3. Connect cables to Power Source
(see page 8 for details).
4. Check to make sure all connections are secure.
5. Turn the inverter On. If the power source is
a DC power supply, switch it On first.
6. Plug in the test load.
The inverter should supply power to the load.
If the inverter is not working properly, refer to
the Troubleshooting Guide on page 17 or Power
and Protection Indicators section on page 15.
7. Test the GFCI Outlet (see page 14 for details).
