Do you know there are 2 RV Electrical Methods to make every thing run? I actually didn’t. If you happen to’re something like me, your understanding of electrical energy is that you simply flip a change and the lights activate.
However once we moved into the RV, the necessity to know turned that a lot larger. Particularly since we supposed to do a variety of boondocking.
Doug has had the endurance of a saint over time attempting to elucidate to me the fundamentals of how electrical energy works. Pay attention, I knew sufficient to ace the check in center college science class, together with our little lab making the lightbulb activate.
On the time I had the method W = A x V memorized. However this was by no means a method I wanted in life. Off it went to the storage cupboard marked “Ineffective Info” in my mind. Nice for Jeopardy. Not for actual life.
By no means did I believe I might be opening that submitting cupboard to tug the ELECTRICITY folder out. However guess what, right here I’m! Not solely pulling that folder out, however having a really primary understanding of that stuff lightning bolts produce. Sufficient to even put collectively an article for all of you besides! Don’t fear – Doug proofread to verify I defined every thing proper.
Sufficient about me, again to the RV.


2 RV Electrical Methods
In contrast to your home, your RV has 2 electrical methods. There may be the system that runs off of the batteries. The batteries are a 12-volt DC electrical system. Your own home doesn’t have batteries. After which a second system that runs off of your shore energy. The shore energy is a 120-volt AC system.
Approach again in kindergarten we realized that 120 is larger than 12. So that you guessed it, your greater home equipment require the Shore Energy to activate. There’s much more too it than that, nevertheless it’s a straightforward place to begin. Notably 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.
However who does what? Are you able to 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 reside 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 sorts of batteries you possibly can have on your RV. However 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. Verify that out for these particulars.


Your RV Batteries are accountable for the important elements of your RV. What’s important then? Take into consideration your automotive for a minute. It runs on a battery. If you happen to flip your key to equipment the automotive wont run, however your lights will come on. Perhaps you’ll have the radio for a couple of minutes. However the automotive itself can’t drive down the highway. Identical factor on your RV.
Your lights will work. So will your water pump (when you flip it on). Your furnace and water heater will hearth up, and your carbon monoxide detector will work. When you have an RV fridge, that shall be working too. In case your RV is provided with a residential fridge, it is going to run, however with the help of an inverter. Which is one other element to the entire electrical energy equation that I’m nonetheless determining. All of these items are “important” elements. So no retailers, fireplaces, or air conditioners.
I’ll go over preserving your batteries charged in just a little bit.
120-Volt Shore Energy System
To ensure that the retailers, your hearth, or your air conditioners to work, you want shore energy. Mostly, 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 may both be a 30-Amp or a 50-Amp wire. (30-Amp has 3 prongs and 50-Amp has 4 prongs) When you plug your camper into the pedestal, you should use the retailers in your camper.


Consider 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 probably not a necessity. Identical goes for the TV. It isn’t going to work with out shore energy. Give it some thought, it must be plugged into an outlet to work, and your retailers aren’t working with out the shore energy.
If you happen to’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 return from a pedestal, nevertheless it does want to return from an outdoor supply. We suggest at all times utilizing an RV surge protector each time your camper is plugged in. See the one we use under.
All Batteries Go To Heaven
Similar to in your little tikes favourite noisy toy, the batteries in your RV gained’t keep charged eternally. Finally they are going to die and go to Battery Heaven. And, similar to little Suzie’s toy, the extra you utilize the battery, the quicker it (they) shall be headed there.
In case your camper is parked in your driveway with the heater set to return on at 65* and it isn’t plugged in wherever, you’re draining your batteries. Similar to for those who left the inside lights on within the automotive in a single day. Bear in mind, the batteries deal with the important stuff. Your carbon monoxide detector is at all times on drawing energy.
The furnace is kicking on, after which the fan to push the air is yanking at these batteries too. To not point out the fridge and any lights you stored on. Left on their very own, batteries will proceed to do their job till they’ll’t. No battery has an infinite lifespan.
So that 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 way of the evening with the entire important methods tugging away at it. Guess what, you thought fallacious. And so did we. Right here is our YouTube Video exhibiting our mistake.
Batteries have to be charged.
RV Electrical Methods Crossover Alert!
Oh My! Simply while you thought you had a deal with on what system was doing what, I’m gonna scramble it up a bit. Whenever you plug your RV into shore energy, it costs your batteries.
WHAT?! Yeah…
That’s the way it works. In any other case, you would need to maintain changing all your heavenly batteries. And in case you didn’t know, they aren’t low cost, they usually die fairly shortly while you don’t cost them. Once we’re boondocking, we make the most of our photo voltaic system to cost the batteries through the day, in order that they keep charged in a single day. We even have a generator for when there’s a variety of tree cowl or dangerous climate.
Alright, one other change-up right here. Your RV could have already got come outfitted with an inverter. If it didn’t, I might extremely suggest 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 doable… It permits you to use a few of your creature comforts even when solely working off of your battery energy.


RV Electrical Finale
At the beginning, don’t go messing round with electrical issues except you’re knowledgeable or have a critical understanding of what you’re doing. I’ll by no means be the particular person deciding what will 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 “- Grasp of None.” And effectively, that isn’t fairly proper as a result of he appears to grasp every thing he does. If I name him a “Grasp of All Issues” his head will get too massive. We reside in a camper. There’s no room for that.
When utilizing an RV you’ll want to perceive that there are 2 separate electrical methods working in tandem to make your tenting expertise marvelous. Understanding which system is doing what’s going to make it easier to broaden that have and will let you do extra off grid tenting in spectacular places.
I’d love to do a observe up article on Selecting the Proper Generator which is able to tie into this one fairly a bit. So look out for that one coming quickly. Within the meantime, drop us a line and tell us the place your subsequent Interstate Journey is!
