RV Solar Inverter Calculator

How to use the RV solar inverter calculator

With so many choices for inverters and inverter/chargers on the market, it can be challenging to determine which one is right for you. We can help you work this out with the calculator below.

Go through and add every electrical appliance you have, their wattages, and whether you’ll be using any at the same time – meaning they will run simultaneously. Then answer a couple of quick questions and we’ll take care of the rest!

Let's start with an inventory of your 120v appliances

How would you like to begin?
Heads up: You can select both options!

Choose from common 120v appliances

If any appliances will be operating at the same time, be sure to select "Yes, runs simultaneously."
Will this run at the same time as anything else?
Would you like to add your own custom 120v appliances as well?

Add your own 120v appliances

If any appliances will be operating at the same time, be sure to select "Yes, runs simultaneously."

Sizing your inverter

An inverter takes DC (direct current) from a battery bank, and converts it into AC (alternating current) to supply power to common household appliances (like TVs, microwaves, etc.). It’s a vital component of any RV or van solar electrical system.

Which inverter is right for your RV or van depends on a number of factors, from the voltage of your battery bank to where you’ll be traveling and which appliances you’ll need to run at the same time. Inverters and inverter/chargers come in a range of models to account for all lifestyles and system sizes, and we’re here to help you find your best fit. 

We want to make sure your solar set-up works for you in real life. That’s why doing these calculations ahead of time is so important: freedom on the road should still be comfortable, and this is how we make sure of it.
