In the event you’re something like me, your understanding of electrical energy is that you just flip a change and the lights activate. Do you know there are 2 RV Electrical Methods to make every thing run? I definitely didn’t. However once we moved into the RV, the necessity to know grew to become that a lot better. Particularly since we meant to do a number of boondocking.
Doug has had the persistence of a saint over time making an attempt to elucidate to me the fundamentals of how electrical energy works. Pay attention, I knew sufficient to ace the check in center faculty science class, together with our little lab making the lightbulb activate.
On the time I had the formulation W = A x V memorized. However this was by no means a formulation I wanted in life. Off it went to the storage cupboard marked “Ineffective Data” in my mind. Nice for Jeopardy. Not for actual life.
By no means did I feel I’d 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 fundamental understanding of that stuff lightning bolts produce. Sufficient to even put collectively an article for all of you as well! 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 programs. There’s the system that runs off of the batteries. The batteries are a 12-volt DC electrical system. Your 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 discovered that 120 is larger than 12. So that you guessed it, your larger home equipment require the Shore Energy to activate. There’s much more too it than that, however it’s a straightforward place to start out. Significantly 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 linked 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 know all of Doug’s classes.
12-Volt Battery System
Lets begin with the little system. And the extra essential one. Your RV Batteries! There are a number of methods to configure your batteries, and much more forms of batteries you’ll be able to have to your RV. However that’s not what this text is about. In Doug’s article about RV SOLAR PANELS he goes into element concerning the several types of batteries. Verify that out for these particulars.

Your RV Batteries are accountable for the vital parts of your RV. What’s vital then? Take into consideration your automobile for a minute. It runs on a battery. In the event you flip your key to equipment the automobile wont run, however your lights will come on. Possibly you’ll have the radio for a couple of minutes. However the automobile itself can’t drive down the highway. Identical 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. You probably have an RV fridge, that will likely be working too. In case your RV is provided with a residential fridge, it’ll 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 “vital” parts. So no shops, fireplaces, or air conditioners.
I’ll go over preserving your batteries charged in a bit bit.
120-Volt Shore Energy System
To ensure that the shops, 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 twine. Now a days that may both be a 30-Amp or a 50-Amp twine. (30-Amp has 3 prongs and 50-Amp has 4 prongs) When you plug your camper into the pedestal, you should use the shops in your camper.

Consider the shore energy as your creature comforts. It’s good to have air-con, however not crucial. 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 shops aren’t working with out the shore energy.
In the event you’re boondocking, dry tenting, or at a campground with out hookup’s, you will get shore energy from a generator. So not all shore energy wants to come back from a pedestal, however it does want to come back from an outdoor supply. We suggest all the time utilizing an RV surge protector each time your camper is plugged in. See the one we use under.
All Batteries Go To Heaven
Identical to in your little tikes favourite noisy toy, the batteries in your RV gained’t keep charged eternally. Ultimately they’ll die and go to Battery Heaven. And, similar to little Suzie’s toy, the extra you employ the battery, the sooner it (they) will likely be headed there.
In case 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. Identical to should you left the inside lights on within the automobile in a single day. Bear in mind, 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. To not point out the fridge and any lights you saved on. Left on their very own, batteries will proceed to do their job till they will’t. No battery has an infinite lifespan.
So that you’re boondocking for the primary time. You suppose the home battery the dealership offered you with ought to keep charged lengthy sufficient to make it by way of the night time with all the vital programs tugging away at it. Guess what, you thought fallacious. And so did we. Right here is our YouTube Video exhibiting our mistake.
Batteries must be charged.
RV Electrical Methods Crossover Alert!
Oh My! Simply once you thought you had a deal with on what system was doing what, I’m gonna scramble it up a bit. Once you plug your RV into shore energy, it fees your batteries.
WHAT?! Yeah…
That’s the way it works. In any other case, you would need to preserve changing your whole heavenly batteries. And in case you didn’t know, they aren’t low-cost, and so they die fairly shortly once 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, so that they keep charged in a single day. We even have a generator for when there’s a number of tree cowl or dangerous 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 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 potential… 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 until you’re knowledgeable or have a critical understanding of what you’re doing. I’ll by no means be the individual 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 nicely, 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 huge. We dwell in a camper. There’s no room for that.
When utilizing an RV it’s worthwhile to perceive that there are 2 separate electrical programs working in tandem to make your tenting expertise marvelous. Realizing which system is doing what is going to assist you to increase that have and let you do extra off grid tenting in spectacular places.
I’d love to do a comply with 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!
