If you’re something like me, your understanding of electrical energy is that you just flip a change and the lights activate. Did you recognize there are 2 RV Electric Systems to make the whole lot run? I definitely didn’t. But once we moved into the RV, the necessity to know turned that a lot larger. Especially since we meant to do loads of boondocking.
Doug has had the persistence of a saint through the years making an attempt to clarify to me the fundamentals of how electrical energy works. Listen, I knew sufficient to ace the take a look at in center faculty science class, together with our little lab making the lightbulb activate. And on the time I had the method W = A x V memorized. But this was by no means a method I wanted in life. Off it went to the storage cupboard marked “Useless Information” in my mind. Great for Jeopardy. Not for actual life.
Never did I believe I’d be opening that submitting cupboard to drag the ELECTRICITY folder out. But guess what, right here I’m! Not solely pulling that folder out, however having a really primary understanding of that stuff lightning bolts produce. Enough to even put collectively an article for all of you as well! Don’t fear – Doug proofread to verify I defined the whole lot proper.
Enough about me, again to the RV.
2 RV Electric Systems
Unlike your own home, your RV has 2 electrical methods. There is the system that runs off of the batteries. The batteries are a 12-volt DC electrical system. Your home doesn’t have batteries. And then a second system that runs off of your shore energy. The shore energy is a 120-volt AC system.
Way again in kindergarten we realized that 120 is greater than 12. So you guessed it, your larger home equipment require the Shore Power to activate. There’s much more too it than that, but it surely’s a straightforward place to begin. Particularly as a result of I wanted electrical for dummies, and perhaps you do too… Who is aware of. I’m not judging. That’s the place I’m too.
But who does what? Can you plug your cellphone into an outlet to cost with out being related to shore energy? Will your fridge or air conditioner work? Will the lights even activate? I didn’t used to know, however now I do! And so are you able to. I’m not promising ease of studying right here although. That half’s on you, and albeit, it took me to dwell in a camper to understand all of Doug’s classes.
12-Volt Battery System
Lets begin with the little system. And the extra necessary one. Your RV Batteries! There are a number of methods to configure your batteries, and much more varieties of batteries you may have to your RV. But that’s not what this text is about. In Doug’s article about RV SOLAR PANELS he goes into element in regards to the several types of batteries. Check that out for these particulars.
Your RV Batteries are in command of the vital elements of your RV. What’s vital then? Think about your automotive for a minute. It runs on a battery. If you flip your key to equipment the automotive wont run, however your lights will come on. Maybe you’ll have the radio for a couple of minutes. But the automotive itself can’t drive down the highway. Same factor to your RV.
Your lights will work. So will your water pump (when you flip it on). Your furnace and water heater will fireplace up, and your carbon monoxide detector will work. If you could have an RV fridge, that will likely be working too. If your RV is provided with a residential fridge, it’s going to run, however with the help of an inverter. Which is one other part to the entire electrical energy equation that I’m nonetheless determining. All of these items are “critical” elements. So no retailers, fireplaces, or air conditioners.
I’ll go over conserving your batteries charged in just a little bit.
120-Volt Shore Power System
In order for the retailers, your fire, or your air conditioners to work, you want shore energy. Most generally, we consider shore energy as a pedestal on the campground. All of our RV’s got here with an influence wire. Now a days that can both be a 30-Amp or a 50-Amp wire. (30-Amp has 3 prongs and 50-Amp has 4 prongs) Once you plug your camper into the pedestal, you should utilize the retailers in your camper.
Think of the shore energy as your creature comforts. It’s good to have air con, however not vital. It’s additionally nice to plug the espresso pot in, however not likely a necessity. Same goes for the TV. It isn’t going to work with out shore energy. Think about it, it must be plugged into an outlet to work, and your retailers aren’t working with out the shore energy.

If you’re boondocking, dry tenting, or at a campground with out hookup’s, you may get shore energy from a generator. So not all shore energy wants to come back from a pedestal, but it surely does want to come back from an out of doors supply. We advocate all the time utilizing an RV surge protector at any time when your camper is plugged in. See the one we use under.
All Batteries Go To Heaven
Just like in your little tikes favourite noisy toy, the batteries in your RV received’t keep charged without end. Eventually they’ll die and go to Battery Heaven. And, similar to little Suzie’s toy, the extra you utilize the battery, the quicker it (they) will likely be headed there.
If your camper is parked in your driveway with the heater set to come back on at 65* and it isn’t plugged in anyplace, you’re draining your batteries. Just like for those who left the inside lights on within the automotive in a single day. Remember, the batteries deal with the vital stuff. Your carbon monoxide detector is all the time on drawing energy. The furnace is kicking on, after which the fan to push the air is yanking at these batteries too. Not to say the fridge and any lights you saved on. Left on their very own, batteries will proceed to do their job till they’ll’t. No battery has an infinite lifespan.
So you’re boondocking for the primary time. You suppose the home battery the dealership supplied you with ought to keep charged lengthy sufficient to make it by the evening with the entire vital methods tugging away at it. Guess what, you thought mistaken. And so did we. Here is our YouTube Video exhibiting our mistake.
Batteries must be charged.
RV Electric Systems Crossover Alert!
Oh My! Just once you thought you had a deal with on what system was doing what, I’m gonna scramble it up a bit. When you plug your RV into shore energy, it costs your batteries.
WHAT?! Yeah…
That’s the way it works. Otherwise, you would need to maintain changing all your heavenly batteries. And in case you didn’t know, they aren’t low-cost, and so they die fairly rapidly once you don’t cost them. When we’re boondocking, we make the most of our photo voltaic system to cost the batteries through the day, so that they keep charged in a single day. We even have a generator for when there may be loads of tree cowl or unhealthy climate.

Alright, one other change-up right here. Your RV could have already got come geared up with an inverter. If it didn’t, I’d extremely advocate getting one. What an inverter does is convert DC energy (your battery financial institution) into AC energy (your shore energy). So bringing that down as merely as potential… It permits you to use a few of your creature comforts even when solely working off of your battery energy.
RV Electric Finale
First and foremost, don’t go messing round with electrical issues until you’re an expert or have a critical understanding of what you’re doing. I’ll by no means be the particular person deciding what might be plugged into the inverter. Doug isn’t an Electrician, however he is aware of what he’s doing. I used to name him a “Jack of All Trades,” however the remainder of that phrase is “- Master of None.” And properly, that isn’t fairly proper as a result of he appears to grasp the whole lot he does. If I name him a “Master of All Things” his head will get too large. We dwell in a camper. There’s no room for that.
When utilizing an RV you want to perceive that there are 2 separate electrical methods working in tandem to make your tenting expertise marvelous. Knowing which system is doing what’s going to make it easier to broaden that have and can help you do extra off grid tenting in spectacular areas.
