What Size Inverter Do I Need For My Camper
What is an Inverter? An inverter is an electronic device that changes DC (direct current) electricity to AC (alternating current). An example of a DC appliance you need an
You'll likely need an inverter size that falls somewhere in the center of the typical inverter range of 1,000 to 5,000 watts. Many people who question what size inverter they need for your RV assume a far bigger size than is really required.
Let's imagine, for illustration purposes, that you need 1,500 watts to simultaneously power your computer and microwave. Consider 1,500 Plus 300 (20% of 1,500), which is 1,800 watts. This implies that you'll need an inverter that is around average in size and at least 2,000 watts. The most typical size used in RVs is a 2000- or 3000-watt unit.
Understanding your power needs is crucial before you can select the correct size of RV electrical inverters. Your inverter is the heart of your RV's electrical system. It transforms DC power from your batteries into AC power for your appliances. It also acts as a charger when plugged in at the campsite.
It also acts as a charger when plugged in at the campsite. The first step with an RV inverter size calculator is to tally up the wattage of all devices you plan to run simultaneously. This includes everything from your microwave and coffee maker to smaller gadgets like your laptop or phone charger. Include everything that uses 110V power.
Most electrical devices run on AC power at 120 or 230 volts, like what you find in your home. This is the type of electricity received from the mainstream electrical grid, and it's, therefore, the power your RV receives when you plug it into shore power. This is why you don't need an inverter when you connect to the grid.
A 3000-watt inverter can run various appliances in an RV, such as refrigerators, microwaves, a single air conditioner, TVs, and small power tools. However, you may not be able to run all of them simultaneously. To check the power draw for each configuration, you can enter multiple concurrent use scenarios into our RV inverter size calculator above.
