Using a Solar Charger for your RV or Camper

Average: 3.7 (3 votes)

Campers tent RV solarWe like to camp.  It started in Arizona when my wife and I were just dating (young, dumb, and broke).  Our level of funding and experience dictated throwing a tent and supplies into the SUV and heading up into the mountains.  We have since progressed on to a popup trailer, and now own a small Hybrid camper - although at 25 feet long some may disagree that it is small or “camping”.  We park it at our Christmas Tree farm and have our own private campsite there too.  The problem is we have no power or utilities way back at the camp.  So I decided to set up a solar charging station to keep the camper batteries fully charged.  Here’s how….. 

RV camper solar batteryOur camper is a Jayco 23B Hybrid.  It’s just like a regular camper trailer except it has big panel doors at each end that pop out (not a popup) into tent ends.  Inside we have the full amenities – stove; microwave; TV; toilet; shower; stereo system and so on.  Most of the time when camping we either have access to shore power (outlets at the campground) or use our Yamaha EF2400 generator which is very quiet.  I love that generator by the way and it’s come in quite handy around the house during storms and power outages….but that’s another article I’ll have to write later.  Sometimes we just like to boondock overnight and run off the batteries – hence the solar charger.

Solar battery MinderThe solar charging system I installed is not intended to be run under load.  It will really struggle to quickly and fully bring a dead system back to life.  What I wanted was a small and inexpensive system to keep the batteries fully charged by using a trickle charge approach.  I hunted around and read all the material available and settled on a 15 watt Battery MINDer charger kit.  It includes the solar panel; a battery minder; a charge controller; and the associated cables.  I would recommend you get a complete kit because you cannot just hook a solar panel directly to your batteries.  They will eventually overcharge your batteries (and ruin them) and you need to have some kind of a monitor and controller to limit the amount of current output.  We have two full size Group 31 batteries hooked up in parallel and the panel keeps them fully charged.  If you really want to overdo it and run with higher loads then you are looking for a 60-70 watt system and a bunch of money too. 

By the way, the Optima blue Top dual purpose batteries are really great for RV use.Optima Blue Top battery

Thanks for sharing. I think many people think solar and see high dollar signs. Although you just wanted a trickle system for your needs, the set up cost (with materials) are far less than the Yamaha generator. I will say though, that the Yamaha is an excellent portable generator, nice picks!

RV Camper Battery Disconnect

If you’re like me, you have every possible gizmo or gadget for your camper from a Digital weather station to that really slick Power Tongue jack. One of the worst situations when camping in an RV trailer (other than a full black water tank) is having your trailer batteries go dead. Now try lifting that power jack or running your RV Water Pump for example. I’ve even had those silly Smoke Detectors and CO Monitors drain my batteries while it was in storage over the winter months. Not any more….

Going to Summer Camp

One way to conquer part of summer boredom is summer camp. Summer camps, when chosen properly, can provide wonderful experiences for your child that last a lifetime. Parents who do their research before the camp experience can rest assured as their child spends time away from home at camp.

Camping Gear Top Picks for Backpacking-Updated

Average: 2 (1 vote)

I have been involved in some "hardcore" camping in the last year. No, I haven't trail run the Grand Canyon from rim to rim. Haven't base camped at the foot of K2. No, I have done something far more dicey. Camping with kids my friends, that is where the action is. In my last few articles, I have talked about some of the challenges I faced camping with kids. To be clear, when I say "camping" I'm using it in a specific sense. . . people+tents+wilderness, preferably light on people and heavy on wilderness.Before my "Let's Go RV'ing" friends get up in arms, I think "campers" are a fine thing but a far cry from "camping". I think they bridge a necessary gap between "Holiday Inn Express" and backpacking but it isn't really my cup of tea. So, if you're looking for places to plug in, that's cool. Just not my thing. I'm looking to "unplug".

So, when I was young, my father's idea of "vacation" meant loading up an Army surplus tent and a cooler of bacon and heading to the great white north which, in this case, was always the same place, Port Austin, Michigan. Not that Port Austin wasn't nice. It was. It had trails, and trees, and a Great Lake. Pretty much an idea spot. For CAR CAMPING. Not really my thing. I'm more of a "middle of nowhere, leave me alone" kind of person.

Fast forward 30 (or so) years in the future. I have my own kids and I want to introduce them to the wonders of the outdoors. Still, it would be nice if they actually enjoyed themselves. I want them to appreciate the wilderness that doesn't include pump stations, electrical outlets and owl shaped string lights. I want them to know the pride of carrying their gear, food and water in and leaving to traces while they are there.
