How to Use Power Inverter in Motor Home?

How to Use Inverter in MotorHome

A power inverter is a useful tool that allows you to convert DC power from a battery into AC power. This can be useful when you’re traveling in a motor home, as it allows you to use AC-powered devices without having to worry about finding a place to plug them in.

If you have a motor home, you may want to use a power inverter to convert the DC power from your batteries into AC power, which is the main purpose of an inverter in an RV. This can be useful if you need to power AC appliances or if you want to use an AC power source while you are on the road.

Here are some tips on how to use a power inverter in your motor home:

Step 1. Choose the right power inverter for your needs. There are different types of power inverters available, so make sure you choose one that is suitable for your needs.

Step 2. Identify where you want to place the power inverter. It’s important to choose a location that is close to a DC power source, such as a battery, and that has plenty of ventilation. Once you’ve chosen a spot, you’ll need to mount the power inverter. Most power inverters come with brackets or clamps that make this process easy.

Step 3. Next, you’ll need to connect the power inverter to the DC power source. This can be done using battery cables or a DC power cord. Make sure you follow the instructions that come with your power inverter to safely connect it to your batteries.

Step 4. Plug your AC appliances into the power inverter. Once the power inverter is connected to your batteries, you can plug in your AC appliances and start using them.

Note: If you are going to be using a portable inverter on the go, let’s say you need to power 120V AC appliances on the go. Simply plug your inverter into a 12V socket, turn it on, and then plug in your desired appliances. However; you should know that your portable inverters typically have a lower capacity than standard inverters, so you won’t be able to run large appliances with your portable inverters.


Do I Need an Inverter in My CamperVan

Yes! But it depends on the size of your campervan. If it has a small diesel engine, then an inverter could be a waste of money.

However, if you are planning to run off-grid, then yes, you will need one power inverter, or a portable inverter is an essential piece if you want to run everyday domestic handy appliances in your caravan such as your charge your phone, PC, desktop, or run any other portable appliances.

Power inverters convert DC power from sources like batteries or solar panels into AC power that can then be used to run AC appliances.

There are a few things to keep in mind when choosing a power inverter. The first is the wattage rating of the inverter, which should be higher than the wattage of the appliances you want to run. And, second; is the DC input voltage, which should be compatible with the DC voltage of your power source.

Should I Leave My Inverter on All the Time in My RV?

In most cases, it is not necessary to leave your inverter on all the time in your RV. If you are not using any devices that require AC power, you can turn off the inverter to conserve energy. But, if you have devices that need to be powered by AC (e.g., a laptop), you can leave the inverter on and plug it into a power source.

However; it is best practice to turn the inverter off when it is not in use. Due to the fact that your inverter can continue to draw power from the batteries, even when there is no electrical load being plugged in. If power is not needed from the inverter, it is advisable to shut it off to avoid unnecessarily draining power from the RV batteries.

Where Does an Inverter Go in A MotorHome?

If you’re outfitting your motorhome with an inverter, you might wonder where is the best place to install it.

While there’s no single answer to this question, there are a few things to keep in mind that will help you make the best decision for your particular setup. We’ll explore some of the factors to consider when choosing where to install your inverter in your motorhome.

There are a few things to consider when determining where to install an inverter in a motorhome.

  • First, think about where you will need to use the inverter and how much power you will need.
  • Second, consider the weight and size of the inverter.
  • Third, consider the type of electrical system in your motorhome.
  • Finally, consult with a professional to ensure proper installation.

The inverter must be mounted in a place that is convenient for both the wiring connections and the operating controls. It is typically mounted near the main electrical distribution panel.

The inverter must be able to dissipate the heat generated during operation, so it must have adequate ventilation. Make sure that the inverter is securely mounted to prevent it from being damaged in transit.

How Long Can You Run an Inverter on An RV?

You can usually run an inverter on an RV for about 12 hours before needing to recharge the batteries. Of course, this depends on how much power you are using and how big your batteries are.

If you are using a lot of power, you may need to recharge sooner. If you have smaller batteries, you might not go longer before needing to recharge.

However; a 150 amp-hour (A.H.) battery will usually provide around 10 to 12 hours of continuous operation for an appliance within a 100-watt. However, this will vary depending on how much the appliance is actually used and how many other appliances are drawing power from the battery.

What Is the Best Size Inverter for A Motorhome?

The best size inverter for a motorhome largely depends on the power needs of the appliances and devices that will be used. A rule of thumb is to choose an inverter that is at least double the wattage of the highest power draw appliance.

For example, if the motorhome has a coffee maker that draws 1000 watts, a microwave that draws 600 watts, and let’s say a tabletop fridge with 15 watts, in total 1615 watts, the inverter should be within 2500 to 3000 watts or more.


To conclude, you should also make sure that you have the safety of your inverter. Make sure that it’s on sturdy ground. Also, make sure that you don’t overload the inverter too much. Overloading can short out your inverter and can cause damage to your appliance or batteries.
