    Power Inverters and your Semi-Truck 

    Whether you are on the road all day, overnight or long-hauling for a week, it is always nice to have some comforts of “home” in your truck cab.

    Bluetooth speakers, a laptop, coolers/heaters and other appliances can definitely make life on the road more comfortable, but they don’t run on diesel. You’ll need a power source to keep everything going – and a power inverter is a great way to do that.

    How do Power Inverters Work?

    Simply put, a power inverter converts the power produced by your semi-truck’s battery from direct current (DC) to alternating current (AC), which is the kind of electricity used in households to power appliances, electronics and so on.

    Choosing a Power Inverter Size for your Semi-Truck

    The size of your truck does not determine the size power inverter you need. The appliances you need to power determines the size. The best way to figure out which size inverter is best for your needs is to add up the wattage of all the appliances you’ll be using. Then add 20%. This will ensure you have enough power to supply them all.

    Even if you won’t be using them all at the same time, if you’re going to spend the money on a power inverter, it’s probably best to get a little more than you need right now so you don’t have to upgrade right away if you add a small refrigerator, microwave or heater.

    Pure Sine Vs. Modified Sine Power Inverters

    There are two types of power inverters – and they are very different. If you use sensitive electronics – such as a CPAP machine that requires consistent, steady stream of electricity, you’ll want a Pure Sine inverter.

    The Modified Sine inverter does not produce as consistent a stream of power, but that doesn’t mean it won’t work with your general appliances.

    Pure Sine is more expensive, but also somewhat less efficient because it uses a lot of power maintaining a steady current.

    That said – if you need it to power the machine that helps you breathe when you sleep, it’s worth the extra money.

    Other Things to Consider

    The last thing you need overnight in your truck cab is to wake up to a dead battery. Most newer power inverters come equipped with an automatic shut off valve that will turn off when your battery reaches a certain low voltage.

    If you work for a fleet, be sure to check with your employer before bringing an inverter into your truck. Some employers do not allow it.

    Also, power inverters don’t care if you drive a Freightliner, Peterbilt or Kenworth truck. They are universal. You just need to be sure you have enough wattage to run the appliances on board.
