LED INDIcATOR AND ShUTDOWN PROTEcTION

5. 

The LEd glows BLUE automatically when plugged into a 12-volt dC source and will 

not glow under the following conditions:

When the power input from the vehicle’s battery drops to approximately 

1. 

10.5-volts, low battery shutdown occurs and inverter shuts off. Solution: 

Recharge or Replace the battery.
When the power input from the vehicle’s battery exceeds 15.5-volts, high 

2. 

voltage protection occurs. Solution: Reduce the voltage range to between 

11-volts and 15-volts.
The continuous load demand from the equipment or device being operated 

3. 

exceeds the continuous load rating of the inverter being used. Solution: 

Use a higher capacity inverter or lower rated device.
The case temperature becomes hot (exceeds 145°F). Solution: Allow the 

4. 

inverter to cool. Do not block the cooling slots or air flow over and through 

the inverter. Reduce the load on the inverter to the continuous rated output.

RESET:

 To reset after shutdown occurs, remove the 12-volt plug from the accessory 

outlet. Check the source of the problem and correct. Reinsert the 12-volt plug into 

the accessory outlet.

POWER SOURcE

6. 

Your average automobile or marine battery at full charge will provide an ample power 

supply to the inverter for approximately 3 hours when the engine is off. The actual 

length of time the inverter will function depends on the age and condition of the 

battery and the power demand being placed by the device being operated with  

the inverter.
If you decide to use the inverter while the engine is off, we recommend you turn OFF 

the device plugged into the inverter before starting the engine. To maintain battery 

power, start the engine every 2 to 3 hours and let it run for approximately 10 minutes 

to recharge the battery.
Although it is not necessary to disconnect the inverter when turning over the engine, 

it may briefly cease to operate as the battery voltage decreases. While the inverter 

draws very low amperage when not in use, it should be unplugged to avoid  

battery drain.
