Why Does My Inverter Cut Out?If you have ever experienced your inverter cutting out, then you will know just how much of an issue it can be.

As it is such an important device, when yours decides to cut out, it can cause a whole host of unwanted problems.

There is not one single reason why your inverter might be cutting out. There could be several reasons why this is happening.

While this can be frustrating, the quicker you can get to the root of the issue, the quicker the issue can be resolved.

That is why we are here to help. In this article, we will be discussing some of the more common reasons why your inverter may be cutting out, and how these problems can be resolved.

In addition to this, if you are new to this terminology, we will be discussing what an inverter is and why it is so important too.

What is an Inverter?

Before we get to the bottom of why your inverter is cutting out, it is essential to know exactly what an inverter is.

An inverter is essential in an RV or van, especially if you want to use standard kitchen appliances. The inverter converts the 12V and 24V direct current (DC) from your RV’s battery and turns it into 230V mains voltage alternating current (AC).

If you are planning on using household appliances when you are off-grid, or while you are not connected up to any electricity points, the inverter allows this.

It transfers the energy so that you can use things such as microwaves, televisions, and computers. Without an inverter, these appliances and electricals would not work.

While DC is used to charge things such as batteries, the majority of electricals run off AC. This is why it is important to have an inverter in your RV or van if it does not already come with one.

Reasons Why Your Inverter Might Be Cutting Out

Why Does My Inverter Cut Out?There are many reasons why your inverter cuts out.

Here are some of the more common reasons.

Lack of Sunlight

As many inverters often run off solar power, if your solar panels are not receiving enough sunlight, there will be less power being supplied to your inverter.

When this power runs out, your inverter will cut out as it needs a supply of electricity to work.

Always ensure that your solar panels are not covered and are in a position to receive as much sunlight as possible.

If this is the issue, when they have sufficient sunlight, they will likely begin to work again.

Battery Charge

If there is no issue with where your inverter is receiving electricity from, you may have an issue with the battery itself.

Always ensure that the wires are all connected and are not damaged.

If this is all fine, then you may need to change the battery of the inverter.

Over time batteries can become faulty, so it is always important to keep a close eye on them.

If you have changed the battery and there is still no power, then there may be an issue with the inverter having burnt rectifiers or melted fuses.

If this is a concern you have, you will need your inverter checked over by a professional as it could be potentially dangerous.

High Or Low Voltage

If your inverter keeps suddenly cutting out, it could be a sign that the voltage is too high. If your voltage is too high, the inverter will struggle to convert the electricity. As an automatic safety mechanism, it will shut itself off.

There are many reasons why your voltage may be too high, such as the connection cable being too thin to carry the voltage, or the overall voltage being over 240V.

If you have noticed that your voltage is too high, we would recommend dropping it slightly. This should not affect your electrical appliances, and it will be a lot safer for your inverter. Fuses and circuit breakers can help to avoid this too.

In contrast to this, a low voltage can also cause problems for your inverter. If the voltage is too low, your inverter cannot work as it should and will therefore cut out.


If you are overusing your inverter this can also cause it to cut out. Overuse is something most people tend to overlook, but it can be an issue. If you have too many electrical items hooked up to the electricity at one time, your inverter has to work overtime.

In addition to this, if an inverter works beyond its operating limit, it can quickly cut out and become damaged. To avoid this from happening, always check that your inverters are running as they should. Check the appliances you are using are not too powerful too.

Faulty Inverter

If you have tried various methods and your inverter is still cutting out, there could be a problem with the inverter itself. It may well be faulty. Over time they can pick up issues.

Take a look at your inverter to see if it has any error messages on the screen. If it does, check your user manual as a reference to see what the problem could be.

If the problem is not something you can address yourself, we would always recommend taking it to be checked over by a professional. While some things can be fixed manually if you are unsure a professional should resolve your issue.


We hope that this article has helped you to identify some of the potential issues that could be affecting your inverter.

While it is frustrating when an inverter keeps cutting out, it is important to remember that there is no one solution to the problem.

Your inverter could be cutting out for several reasons, such as high or low voltage, loose wires, battery issues, inverter faults, overuse, and lack of sunlight.

We recommend looking into all of these issues before you decide to replace your inverter.

However, if you have any concerns, or cannot resolve the issue yourself, it is always best to seek help from a professional.
