Sometimes small systems are plenty

Friday my wife suddenly got the urge to camp. Immediately.

All the TT has is the original Group 24 battery, 5w solar to maintain it and a 700w/1500w inverter I've never even run under significant load. I didn't really need the system to do a lot since at 103 degrees in full sun we will be absolutely doing full hook ups.

Fired up the fridge at 8 am on propane. Pupmed the over chlorainated full water tank almost dry to be ready for use. Ran the compressor from home on the inverter to air up all 4 tires and headed to work.

At noon the freezer and fridge were cold so she loaded but did not even run the fan as the camper still held the cool from overnight.

1:05 PM we headed out for Fredericksburg and wine country.

The current set up is barely above factory, but the battery was brimming with charge and the inverter did everything we would have wanted except for the AC.

I actually think it is the ability to use the microwave that will finally push me to get the Deka AGMs put in the TT. Putting them in will mean i pit in the solar charger to maintain them without cooking the, dry or leaving the discharged. Other than the microwave though, there is just no burning need for us at the moment.

Now if I went crazy and got enough batteries and inverter to run the AC for an hour 15 times a year, that would he a horse of a different color.

    Planning, yes. And habits/whims. I used to do 3 weeks wilderness trips in a kayak, no stores on the way. Had full balance of meat protein (no hunting allowed, and fishing wasn't good), and the use of propane stove 3-4 times a day. Batteries? Let me see... 6*AAA, 8*AA. No solar, and there was not much need to carry small charger - could've easily carried a double amount of batteries if I had to.

    Camping for us is to have all the PLAN Bs we can think of... We are smaller than your foot print wise and really enjoy it...

    We can stay out for a good two weeks and run all of our toys everynight with the game plan of having enough battery capacity to do it and a fool proof way to recharge the batteries the next mornings to let us keep doing it all over again... About the only thing we do without is Air Conditioning...

    It does take alittle planning however to make it work SUCCESSFULLY

  • Have some in mind but you know, camping comes first.

    I was thinking about maybe some kind of flexible battery box that could accommodate a variety of batteries over time, and make changing them out easy.

    I also like the idea of batteries plus Inverter external to the RV like we have been discussing in the other thread. Seems like a small bank or even single break away battery might be enough for me on the TT! With solar, AGMs and inverter in the truck. Hook up would be the AC power cord plus a short heavy gauge DC-DC connection between battery banks to avoid conversion losses.
