SOURCE POWER
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 if 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 vehicle engine.
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 PW900-12 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.
