Power Inverters for Semi Truck – Buyer’s Guide!

If you’re in need of a new power inverter we’ve done the homework for you. Continue reading for a buyers guide on the best power inverters for semi trucks.

Do sometimes or always have issues with long hauls where you need to power up some specific home appliance and find you can’t? Well, that’s all got to do with the power supply, and guess what? Your truck is a DC powerhouse, so that’s why you can’t power up to AC based appliances.

Now, in many cases, some devices, mainly mobile and small electronics, come with converters, but in most cases, such as toaster oven, a hairdryer, and other non-mobile, non-IoT devices require a solid AC source of power and do not connect with USB connectors.

This is where a standard power inverter comes in to play.

Power inverters convert DC currents into AC, and I will not go into the science of the mechanism, just state that this technology has been around since Tesla first invented back in the 19th century. (Oh, yeah, for all you youngsters, Tesla is not a car manufacturer, he was an actual human being that lived a century or so ago and is considered one of the fathers of modern electricity).

Power inverters work by converting DC to AC, so, first of all, you need a DC source of power, which luckily you have in your vehicle battery. Now comes the tricky part, there are different kinds of inverters that provide different levels of power, and you need to know which battery you have before you buy an inverter.

So, either buy a universal one that works along with a wide range of vehicle power sources or buy a bespoke one focused on your specific battery type.

The different sizes include 1000, 1500, 2000, 3000 or 5000 watts. Now, some might state you need a 3000-watt inverter, and this is considered to be the mid-range inverter. However, I find that the best inverters tend to be specific for different application requirements, so even a “weak” 1000W inverter will do the trick, and might be safer than an overcharged 5000W unit.

Consider the power applications or watt usage your devices have, are you connecting a refrigerator, washing machine, and central a/c unit? I doubt that 1,000W is enough to power a small house in a blackout, so anything more than this is an extravagance, and power for power’s sake is a waste.

As such, I prefer to concentrate on standard power usage and concentrate around the 2000W mark, which is more than enough for even a busy campsite, or for powering up a couple of compressors for work.

There are also two different inverter methods, one is the modified sine wave, and the other is the pure sine wave inverter. The modified sine wave (MSW) is a cheaper and less powerful model, and are used for powering up every day electronic devices. The pure sine wave (PSW) models are more powerful and compatible with every device you want to connect.

In this article I present you with five of the best inverters for your semi-truck applications, and bring you the value for money brands and makes, this means these models are all under 3000W, three are MSW’s, and two are PSW’s. You will do well with all of them, unless you need an inverter to power a small village, in that case, I suggest an inverter above 3000W.
