How to Install a Power Inverter in a Vehicle

by Don Bowman

Some power inverters are designed with a bracket with holes in it for a hard mount with the use of screws, and some are not designed in the same manner. Keep this in mind when purchasing an inverter for your vehicle. Make sure it has a bracket, unless a temporary installation is preferable. Inverters without mounting brackets can be mounted using velcro strips.

Determine the location for the inverter. Keep in mind that the inverter must be in an area allowing air circulation to keep it from overheating. All inverters have an internal fan, which should be kept clear to allow airflow. The negative and positive cable must pass through the firewall to the battery. The last consideration is that the location must allow accessibility to turn the inverter on and off.

Place the inverter on the bottom of the dash or on the side kickpanel. Hold the inverter up to the location and mark the holes. Drill the holes. Install the screws and tighten them with the screwdriver. If the inverter does not have a bracket, use the velcro strips. Cut strips of velcro to fit the underside of the inverter. Pull the plastic strip off the sticky side and press the velcro on the inverter. Stick the opposite side of the velcro onto the piece on the inverter and remove the plastic from the back of the velcro. Press the inverter with velcro attached to the dash location.

Run the positive and negative cables through the firewall to the battery. Loosen the battery terminals and install the red positive wire to the positive terminal on the battery and the black to the negative terminal. Tighten the terminals firmly.


  • check All inverters have an on and off switch with a red light to indicate they are working. Always turn the inverter off when starting the vehicle. Always remember to turn off the inverter when turning the engine off when exiting the car. Don't forget, the inverter fan is always working when the switch is on, even with the car off. You will be an unhappy camper in the morning if you come out and the battery is dead.
