• Double check all wiring for proper polarity.
• Install the fuse and reconnect the wire to the battery. Note, a slight spark and beep from the
inverter is normal when the unit is first connected to 12 volt power.
Advanced Installation
Large inverters can draw high currents from your battery and charging system especially when used
with appliances and tools that use a lot of power. In these applications, you may need to increase the
capacity of your 12 volt system. There are several ways to do this.
High Capacity Batteries
You can purchase high capacity batteries that are specially designed for deep discharge operation.
Contact your automotive or RV specialist for more information.
Multiple Batteries
In systems with more than one battery, you typically wire the system with the batteries in parallel
(negative to negative and positive to positive) with a battery isolator between the positive
terminals. The isolator allows a single alternator to charge all batteries but lets the inverter only
use the second battery so the vehicle’s battery is not discharged during operation. Contact your
automotive or RV specialist for more information about battery isolators and wiring.
Larger Alternator
Typical automotive alternators may not be able to supply the power required for continuous
operation of the inverter at high power usage. Contact your automotive or RV specialist for more
information about larger output alternators.
Step #3: Testing the Power Inverter
After you make sure the 12 volt power is wired properly to the power inverter, with nothing plugged
into the 115 VAC outlets, turn the power switch on the power inverter to On. The green POWER
light will light.
Note: If the inverter does not operate properly and the POWER light does not illuminate, turn the
power switch off and check your wiring and external fuse.
With the inverter turned off, plug the appliance you want to use into the 115 VAC power outlet on
the unit. Turn the power switch on the power inverter on so the green POWER light is illuminated.
Turn on the appliance. The appliance should now be operational.
Check the Troubleshooting section if you have any difficulties.
Operation
Equipment Power Usage
It is important to use only products that draw less than the power rating of the power inverter. Use of
products greater than the rated power rating may either cause the protection circuitry of the power
