Once you’ve figured out that you need an inverter for your truck so that you can maintain a reliable power supply for your devices without draining the battery, it’s time to install the inverter.
In this article we explain exactly how to install your new inverter on your truck.
Step-by-step instructions of connecting the inverter
Most inverters over 150 watts require wiring and fuses to connect the inverter to the car battery. You can easily connect an inverter of less than 150 watts to the cigarette lighter of your truck.
- Choose where to place your inverter
They can often be found in the glove compartment or under a seat. Some experts even recommend attaching it to the truck bed wall, which is accessible and easy to keep clean and dry.
You want the inverter to be in a dry place, but not in a place where it can overheat. It should also be close to the truck battery to avoid wasting precious wattage.
If it is necessary to drill holes in the truck, make sure that there are no obstacles on both sides and that it is safe to drill. Also make sure cables are away from moving parts or hot objects.
- Wire (red and black)
- wire cutters
- Measuring tape
- Cordless drill and accessories
- Plastic cable ties (to keep the cable in place)
- aluminum tape
- Circuit breaker (optional)
- Map out wires
Now that you have a mapped path for the inverter cables, you need to route two cables (one positive and one negative) through the path. It is important to choose the right cable for this job, as the wrong cable can cause power outages.
Use zip ties to hold the cables in place, and if you’ve made a hole through the firewall, wrap the cables with aluminum tape to protect them. If the cables go through the cabin, you must seal the hole with waterproof sealing glue to keep the cabin dry.
Mount the inverter in place. Do not rely on glue, make sure the inverter is firmly fixed with screws.
Trim excess wire and add grommets, confirming they are the correct size for the wire and for your particular terminal.
- Circuit Breaker (optional)
If you have purchased a circuit breaker, now is the time to install it. Place it on the positive (+ red) battery terminal, as close to the battery as possible, and use sheet metal screws to secure it.
Install grommets on your cables if you haven’t already. The grommets should match the bolts on the battery terminals, so remove the nuts to secure them.
Connect the positive terminal first and then the negative terminal. Cross your fingers to avoid sparks or smoke.
Congratulations! You have installed an inverter on your truck!

Emphasis on safety
The advantage of an inverter is that you can safely charge a multitude of electrical devices without endangering your vehicle’s battery. However, it requires careful maintenance.
As with any project, inverter wiring must be done carefully to ensure that power does not rush to supply power to one outlet at a time. That would potentially destroy anything plugged into the outlet.
Furthermore, poor maintenance or bad installation can also make the inverter a fire hazard, so always make sure that everything is well maintained and connected.
Special features to be aware of
Many inverters have a fan and it needs to be cleaned from time to time to remove debris. If the batteries mounted directly on the inverter leak, they will also cause damage, so it is better to use a sealed battery to avoid damage.
Finally, an inverter is susceptible to damage from high temperatures or water, so make sure the inverter is not left cold and dry.
Installing an inverter is relatively easy and following these two instructions and any other instructions that come with your chosen inverter will ensure easy and safe installation of your inverter.
