Top Power Inverter for Semi Truck Buying Guide

You can bet that picking out the best power inverter will be a difficult task especially if you are a beginner. You need to consider a few crucial factors some of which we discuss below.

Inverter Size

What is the ideal size for a power inverter? When you ask the experts, the usual answer will be the bigger it is the better. 

This is quite understandable because a bigger inverter will be capable of handling all your power needs while you are on the road.

That said; this is a common misconception that you need to keep in mind.

Granted, a bigger inverter provides greater power but you need to keep in mind that picking the right inverter calls for you to align its specs with those of your energy needs.

Should you fail to do that, you may end up with an inverter that is overly powerful that will consume a lot of energy, or one that is too small to power your cabin appliances. Of course, you will have wasted your money in both scenarios.

To avoid this, you want to list all your appliances and their wattage needs. This will help you choose an inverter that can power all your appliances without causing wastage.


Semi-truck inverters operate on either modified or sine wave. Both are great but you may want to go for sine wave if you will be dealing with sensitive electronics.

The thing about sine waves is that it works on practically all appliances and does not suffer from power fluctuation. This means that it provides a dependable output stream.

However, if you do not have any sensitive appliance in your semi-truck, a modified sine inverter will serve you just right.

One thing you need to keep in mind is that sine inverters are costlier than modified ones and you do not want to spend more to get a sine inverter when you have no sensitive appliances.

Shutdown Technology

Although a power inverter is an invaluable device when it comes to supplying power, it can also adversely affect the battery life of your truck.

It can also crank the engine especially if the inverter lacks shutdown capability. To be on the safe side, you want to get an inverter with the auto-disconnect feature.

This allows the inverter to safely shutdown should the voltage level go below 12 V DC.

Ease of Installation

Your local technician will not have any issues installing any kind of inverter in your semi-truck. Of course, this is because they have the training and skill to do it.

However, if you prefer going the DIY route, you may want to buy an inverter that is easy to install or one from a manufacturer that offers some sort of training as far as installation is concerned.

This will ease the installation process and answer any questions you may have.

That said, you want to keep in mind that you will be dealing with hardwiring and fusing if your inverter has more than 300 watts.

If this is the case, you may want to acquire some knowledge and skills on the same, and while at it, ensure that there is enough ventilation in your truck to allow the dissipation of heat.

Finally, you want to purchase an inverter with a warranty mostly because of the risks associated with the device. Alternatively, you can go for a factory-installed one.

Safety Ratings

You should always prioritize safety. One thing you should know is that despite the size of inverters, they can generate electric shocks that can injure or even cause death.

As such, it is important to choose a safety-rated inverter. Pick one with a UL listing if you are in the US and even after doing that, ensure that you handle it carefully.

Observe basic electrical safety principles and buy your inverter from a reputable retailer.

After handling safety ratings, you want to look at the safety features of an inverter before purchasing it. This will guarantee the longevity of your appliances.

You want to ensure that your inverter has safety features such as in-built fuses and safeguards against common hazards like over-voltage, under-voltage, short-circuiting, and overloading.

Employer Safety Check

This only applies if you work for a fleet company or drive a semi-truck on behalf of someone else. You want to first check in with your employer before installing any inverter on the truck. 

This is because some trucking companies have equipment and insurance stipulations in place that either encourage or discourage outfitting the cabin. You do not want to find yourself on the wrong side of the law, do you?

When you get consent from your employer, there will be no issues.

Cost of Inverter

Irrespective of the inverter you pick, it all boils down to cost. These devices can be affordable and they can be very costly.

Pricey inverters generally perform well and come with an assortment of features compared to their more affordable counterparts. However, this does not mean that a costlier inverter will be most suitable for your truck.

As we have previously mentioned, different truckers will have different needs hence the varying inverter choices.

Therefore, you want to go for an inverter that will satisfy your power needs and that is within your price range.

Pure Sine vs. Modified Sine Wave Inverter

We have mentioned sine and modified inverters throughout this review and you are probably wondering what those terms mean.

They are essentially the power through which inverters operate and it is important to pick the right one for your semi-truck otherwise you risk damaging your appliances.

Let us, therefore, look at the difference between the two and which one will suit you best.

Pure-Sine wave

When we talk about pure-sine, it is the power obtained from a generator or power supply company. Now, the greatest advantage of an inverter that uses pure sine is that it is suitable for all kinds of appliances and tools.

This means that all your appliances will function optimally when you are using this kind of power and the risk of electric damage is very low.

Nevertheless, pure sine inverters cost more than modified inverters.

Modified Sine wave

A modified Sine wave inverter is only capable of powering some household appliances and tools. We mean those with reduced efficiency.

As such, if you are looking to power any appliance that has a motor like a pump fan or refrigerator using modified sine wave, it may not work at all.

This kind of power can power fluorescent lights but they will not be as bright and they may generate noises when switched on. Other devices such as clocks may malfunction when using this power.

Therefore, a modified sine inverter is only ideal if you are using simple appliances that use a universal motor.

How to Install a Power Inverter in a Semi-truck

You can decide to hire a professional to install your inverter to your truck but if you decide to do it on your own, here is the process.


Everything starts with a plan and it is not going to be any different with this. You want to plan prior to installing so that you do not mess up your job.

Therefore, place your inverter in an easy to access area that is dry and properly ventilated. Do not place any large objects to the inverter as they may cause damage.

Ensure that the inverter is installed close to the truck’s battery box for an easier installation process.

Create Cable Holes

Following user instructions to make enough holes for wiring and cables. You want to line these holes with something like rubber to prevent them from scratching on the exterior of your inverter.

Be sure to remove any rugs, carpet, or mat on the area before making the holes.

Set the Wires

The inverter’s battery is full of electric current and you may, therefore, want to get professional help when it comes to installing the ends.

You can contact the manufacturer of the device or get help from an electrician.

Fit the Fuse

Most inverter manufacturers claim that their products have in-built safety mechanisms. However, it is important to fit your inverter with a fuse just in case.

Inverter installation kits normally come with the fuse and holder that will be fixed into the battery box. As you set the holder, be sure to leave enough room for cable connection.

Fix the Inverter

The next thing you want to do is mount your inverter. Remove anything that can hinder proper ventilation where you want to fit your inverter.

Connect all cables and wires to the inverter and reinforce them with rustproof screws. You then use an aluminum sheet to provide extra protection to your device. Just ensure that this sheet does not hinder heat from escaping.

Link the Remote Button with the Device

The best place to place the remote is in the sleeper because that is the place you will occupy most when using your inverter.

Another reason is that that is where you can get enough space for the switch button.

Reasons Why Your Power Inverter May Fail to Work

You cannot deny that a power inverter is an extremely useful device for both homes and homes away from home.

With this device, you get to enjoy convenience and functionality even when you are on the road. Therefore, you can imagine the frustration you will feel if it suddenly stopped working.

You will have no way of communicating with a dead-battery phone, and you will have to eat cold food since your microwave will not be able to warm it for you.

We have discussed some common reasons why your inverter may fail to work and offered appropriate solutions below.

Faulty Power Button

One of the commonest reasons why inverters fail to work is because of a faulty power switch. Therefore, when you realize that your inverter is not powering any of your appliances; you may want to unplug it from the power outlet and plug in a different appliance to see if it powers on.

If the appliance does not power on, then your power button may be defective. If that is the case, you may want to get a professional to replace the power button.

Tripped Inverter

Tripping could be another reason why your inverter fails to work. To counter this, you want to press the trip reset button, which is located on the inverter.

What this does is to reset the inverter and turn it on. If this fails, your inverter could have other issues so keep checking.

Disconnected Battery 

Perhaps your inverter is not working because the battery is not properly connected or it is disconnected altogether.

As such, you want to check if the battery is in place. If not, connect it well and try switching on your inverter.

Corroded Battery Terminals 

Batteries are prone to rust and that could be another reason why your inverter fails to work. You, therefore, want to examine your battery terminals to find out if they are corroded.

If you notice any corrosion, take a dry piece of cloth and try wiping the area. Place the batteries back in their slot and turn the inverter on.

If it fails to work, then you may need to keep looking for the problem.

Defective or Weak Battery

If you have checked for all the above issues and tried to solve them and your inverter still fails to power on, then it may be because it has a weak or defective battery.

In that regard, you may want to replace the battery especially if it is too old or recharge it.

Discharged Battery

A discharged battery can also cause your inverter not to function. To that effect, you may want to recharge the battery and putting it back on to see if the inverter works.

If after trying all the aforementioned solutions your inverter still does not work, you may have to seek professional help so that the problem can be diagnosed and treated.

Frequently Asked Questions

We know you may have a few questions with respect to this topic and we are always up to the task. Although we cannot answer all of them here, we have tried to answer a few commonly asked ones below.

Which is the most reliable power inverter for trucks?

This will entirely depend on the kind of appliances you intend to run and the frequency of usage. This is because each appliance operates at its own capacity.

For instance, a laptop operates at 20-75 watts while a coffee maker needs 600-1000 watts. These readings are not precise because then again, it will depend on the brand of the appliance and its size as well.

As such, you want to check an appliance before purchasing it to ensure that it suits your inverter.

Can a 300-watt inverter power a TV?

Yes, it can. You can connect 300-watt power inverter to your car’s battery through the DC plug that is located on the dashboard.

Typically, inverters come with one or two standard sockets to power phone chargers, laptops, and small-screen televisions.

Is it necessary to own a device for power surge protection?

Yes, it is. It is important to have such a device even if your inverter has an in-built fuse. The device will help regulate voltage and protect your appliances from electrical damage.

Can I power my refrigerator using an inverter?

Yes, you can but it has to be a pure sine inverter and not a modified one. You will have to use an inverter that delivers high wattage since an average refrigerator needs 6-7 times more surging than other common appliances.

Therefore, if your inverter reads 400 watts, you will have to plug it into a 3000 watts inverter.

What appliances can I run with a 1500-watt inverter?

That kind of inverter is suitable for running small home appliances such as microwaves, cell phones, televisions, laptops, air conditioners, and the like.

If you need to power larger appliances, you may have to get an inverter with more wattage.

What is the best size power inverter to run power tools?

Again, this depends on the tool you intend to power. For instance, if your television draws 100 watts and your microwave another 100 watts, you will require an inverter with a minimum of 300 watts.

If you plan to power an appliance that uses a motor, you will require extra wattage to start it. This means that the minimum wattage has to be much more like three times the continuous wattage needed.

Does an inverter draw power when not in use?

For an inverter to run, it requires about 10% more than the energy load of the appliances it powers. This is because of the inverter’s efficiency.

To answer this question, yes inverters do draw power from batteries even when they are not in use as long as the unit is switched on.

Can I leave my inverter on all the time?

Yes, you can but it is advisable to turn it off whenever you are not using it. If your unit combines both inverter and converter functions however, you may want to leave it on.

Turn the inverter off if it is necessary to keep its batteries from fully discharging.

Can I charge a battery while using an inverter?

Yes, you can but do not make a habit out of it particularly if your system is not linked to the mains. This is because for you to recharge your battery using an inverter, you have to do it through the AC mains.

Once it is recharged, you can then use the inverter socket to charge it again.
