RV Electricity


We have some learning ahead of us with the new coach. The electrical system is the one that will likely take the most effort on our part. We don’t know how to use electricity on a coach.

Well, I mean we know how to turn things on and plug things in. We just don’t know how all of the various systems work together.

Our coach will have three separate electrical systems: 12-volt automotive DC, 12-volt DC coach and 120-volt AC coach. Power will be generated from multiple sources including the on-board generator, shore, batteries and eventually solar. We will have an inverter, an automatic transfer switch, an automatic generator start on low battery, a surge protector and an energy management system.

In short, if you will pardon the pun, we will have a complex electrical system to manage.

There are several resources that I found very helpful in terms of learning more about the electrical system of an RV.

The first one is from RVTechMag.com.

I’ve created this tutorial to help explain some of the basics of electricity as related to RVs. It’s certainly not going to turn every RVer into an electrical engineer or service tech but it may help many of us to better understand the basics of electricity and how it relates to RVs in general. I’ve organized and categorized topics so that they begin with raw basics and build from there. That way you can either start at the beginning or skip the stuff that you know and go right to your area of interest. You can use this as a study course if you wish or simply a reference source to refer to as needed.

The second is from RV-Dreams.com.

I was thinking about what I should cover in a “Basic RV Electrical” section. Then it dawned on me that I would want it to be really, really basic. I asked myself this question: What is the absolute minimum I need to know about my electrical system…

Gone With The Wynns offers a lot of great video tutorials on solar.

Solar power is our main source of electricity on the road and we’ve learned way more about it than we ever wanted to! From our current and past RV Solar Systems to simple explanations on what it is and how it all works, we try to keep things as simple as possible with these complex RV electrical systems. Click on any of the posts below for more information on solar, inverters, chargers and portable power.

And finally the RV Geeks offer a variety of video tutorials on electricity for RVs.
