Most automobile and marine batteries will provide an ample power supply to the inverter for
30 to 60 minutes even when the engine is off. Actual time may vary depending upon the age
and condition of the battery, and the power demand being placed on it by the equipment
being operated with the inverter.
If you decide to use the inverter while the engine is off, we recommend that you start the
engine every hour and let it run for approximately 10 minutes to recharge the battery. We
also recommend that the device plugged into the inverter be turned OFF before starting the
Although it is not necessary to disconnect the inverter when turning over the engine, it may
momentarily cease to operate as the battery voltage decreases. When the inverter is not
supplying power, it draws very low amperage from the battery and may be left connected
to the battery for up to three hours. However, we recommend the inverter always be disconnected
when not in use.
INVERTER PROTECTION FEATURES
The RED LED Indicator light will turn on and the inverter will turn itself off automatically
1. The power input from the battery drops to 20 volts. (When the power input drops to 20.6
volts, an alarm will sound for an extended period).
2. The power input from the battery exceeds 30 volts.
3. The continuous draw of the equipment or appliance being operated exceeds 400
4.The surge draw of the equipment or appliance being operated exceeds 800 watts.
5. The circuit temperature exceeds 165 °F.
The inverter is equipped with a thermal fan which is designed to run if the inverter should
need to be cooled while the inverter is operation. Automatic shut down caused by high
circuit temperatures will occur when the cooling fan is unable to maintain a cool enough
temperature for safe operation of the inverter.
In the event of automatic shut down or continuous audible alarm, turn the inverter rocker
switch to the OFF (0) position until the source of the problem has been determined and
