Many wonder what size inverter they need for their RV and estimate something far larger than necessary.
Do RV batteries need an inverter?
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. Your batteries, however, run at 12V DC power.
How many watts does an RV inverter need?
Take 1,500 + 300 (which is 20% of 1,500) = 1,800 watts. This means you'll need a pretty average size inverter of at least 2,000 watts. A 2000- or 3000-watt unit is the most common size used in RVs. Does the Inverter Need to Power the Whole RV? Thankfully, no. If this were the case, we would all have to purchase very powerful inverters.
How do I choose the right RV electrical inverter?
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.
