7 Operation and Troubleshooting
7.1
Operation To operate the inverter, switch the output circuit breaker switch to "ON". Also switch
"ON" the remote on/off switch (if used).
The battery voltage must be higher than 9 volts for the inverter to operate.
7.1.2
Turning the inverter "ON": To turn the inverter ON, set the On/Off switch to the "On"
position. The green "Inverter Power" LED will light.
Turn the inverter OFF when not in use. There is an approximated 1 to 2 amp DC
draw from the batteries at idle or no load.

A TRUE RMS voltmeter is required for accurate AC output voltage measurements on a quasi-sine
inverter. A voltmeter that uses averaging circuitry will give incorrect measurements.
Unplug all loads and connect a 100-watt light bulb to the inverter output. Observe the LED Status
Panel then check troubleshooting Table V.
PROBLEM
No LEDs: No power output. The
inverter is not connected to the
batteries; the battery voltage is
below 9 volts DC or there is a
fault in the remote On/Off circuit.
Low battery: Red LED indicator.
Indicates that the inverter has
shut off due to a low battery
voltage condition.
Overload: Red LED indicator.
Indicates that the inverter has
shut off due to an overload
condition.
High Temp: Red LED indicator
light. Indicates that the inverter
has shut off due to high internal
temperature.
The
automatically turn back on when
it has cooled to 40°C (104°F).

Check the in-line fuses for continuity. Make sure the DC wires are
clean and tight. Check the DC voltage at the inverter DC input.
Check or bypass the remote On/Off circuit.
Fault in the battery wiring, battery capacity and voltage or the in-line
fuse. The inverter will shut off after 2.5 seconds. Switch the inverter
off then on to clear the error.
The inverter output wiring is shorting or loads exceed the inverter
rating. The inverter will shut off after 2.5 seconds. Switch the
inverter off to clear the error. Remove the short circuit or excessive
load from the output, and then switch the inverter on.
Verify that the inverter is in a vented compartment and that the fan
is not blocked. High ambient temperatures combined with poor
ventilation may also contribute to the shut down.
