How to buy the best power inverter for semi truck

It is a challenging task to buy the best semi-truck inverter, especially if you are new in operating the truck. If you want to buy the best and reliable power inverter that can meet your needs, you must keep many factors in mind. 

You need to check the inventor size, the total number of appliances that you want to connect to the inverter, total wattage that is required for the appliances and budget.

Here are a few factors you must consider to buy the best inverter for your needs

Inverter size

Many will buy the bigger inverter as it caters to the needs of the truck driver. This is a misconception that many have. The bigger size of the inverter would indeed offer you high power, but you need to choose the one that meets your specifications and needs. This saves a lot of money and space. 

When you do not determine your needs and buy a small or big size inverter, it won’t fit in the cabin and would eventually result in wastage of your investment. You must get the powerful inverter. You must first make a list of appliances that you want to use in the semi-truck. It helps you to get the list of wattage needs. The total wattage will help you find the best model inverter. 

You must learn that the running wattage would not have any impact on the surge power that you need when you want to start up the power-hungry appliances.

No matter whatsoever inverter you want to choose, you must have an idea about the wattage of the appliance, and you must select the one that has an additional 20-wattage, and that meets your power needs.


There are two different types of waveforms with which the inverter will work. These include the pure sine wave inverter, and the other is the modified sine wave inverter. You can use either of these inverters to set up in the cabin. However, if you are particular about the usage of sensitive devices, it is better to buy pure sine wave inverter.

Sine wave works on all the appliances and would not produce any kind of fluctuation in power. It provides a stream of output. 

In case if you are using sensitive appliances, you must go for a pure sine wave. Otherwise, you can buy the modified sine wave inverter that helps you operate the appliances and electronics uninterruptedly.

Moreover, the sine wave inverters are quite expensive. The modified inverters are 15 to 20% lesser in price compared to the pure ones. The irony is that the efficiency of sine wave inverters is lesser since it has to keep the output consistent always.


The inverter will provide you with the required power to run the appliances continuously, but it takes a toll on the battery life of the semi-truck. There are high chances for the engine to work cranky. The inverter cannot shut down automatically. You must use the inverter with the auto-disconnect feature. It allows the inverter to shut automatically once the voltage level is below 12V.


It is tough for you to find the local technicians to install the inverter in the truck safely. You can buy the inverter that is easy for you to set up. There is also an installation procedure provided to you with proper guidance. 

If you are using the inverter that is above 300 watts, there comes the role of fusing and hard wiring. You must know the wiring part. There should be enough ventilation to allow the heat to vent out instead of getting accumulated at one place and damaging the equipment.

Safety ratings

Safety is the priority and is the critical factor you must consider when you are buying the power inverter for the truck. Irrespective of the size of the inverter you are buying for the truck, there are high chances of it to get prone to electric shock.

It results in injuries. You must choose the inverter that meets the safety standards. The inventor must protect the appliances from various hazards such as overloading, short circuit, under-voltage, and over-voltage.


It is the pivotal factor that many must consider when buying the best inverter for the semi-truck. The inverter will be available in different price ranges. The inverters that are highly powered would come with impressive features. 

Every truck has different needs, and the choice of the inverter varies from one truck owner to another truck owner. You can choose the inverters within your budget range rather than going beyond your budget and buying something that comes with many bells and whistles which you do not want.

Battery type

You must make sure to purchase the inverter with a long battery life. The batteries will store energy either from the renewable energy or power station. The performance of the inverter depends on the battery quality.


You can enjoy the convenience of your long truck trips by having the right inverter. It allows you to connect the appliances that are required for you to lead a satisfying life, even on the move. We have listed five best power inverters for semi-trucks.
