New RV Owner with power(solar) questions.

Hi Everyone, I've enjoyed reading through the forums, and finally joined! I appreciate the wealth of information that is accessible here.

My wife and I recently bought a 1985 LeisureCraft. It's in pretty decent shape, although it needs some work. I recently had the generator serviced, replaced all the taillights, and just had a full tune up done on it. Seems to be running like a champ!

I've some questions about powering the RV, specifically with solar. I've read a bunch of stuff but I'm having a hard time fully wrapping my head around the idea. Currently there is no power converter in the RV. So I'm assuming my generator won't even charge the battery. Is this correct? It's got a 6v marine battery in it that's old, and I assume it will need to be replaced. All that I've read is that it might behoove me to get 2 6v golf cart batteries and wire them together. We will be primarily boondocking for a week at a time with no access to anything. We will run our generator sparingly and sporadically when we need to break free of the desert heat, and turn on the AC. I would like a solar solution to keep the batteries charged for recharging camera batteries, running the water pump, etc. Where is the best place to start? We will be frugal with our power consumption, but would like to insure that it's there, and available for us to use. I found the following solar kit, though the reviews say the charge controller is a piece of junk. Would this kit seem like enough to keep me alive with my above requests?

My generator technician also suggested I look intelli-power 9200 series as a converter. I'm still not able to wrap my head around how all these things play together. Is that primarily for when it's plugged into shore power? Thanks in advance for any and all advice! We are looking forward to getting on the road in this thing!

    amazing! I'll read this once I put the little man down for bed. Hadn't found this one in my googling! Looks pretty comprehensive, and starting at the basics. Thank you!


    Wow! That was informative! I learned a ton reading that. So tell me if where I've settled is "correct". I'm thinking that 2 golf cart deep cycle 6v batteries wired together will suit my needs. Is the 200watt solar kit I liked above adequate to keep ~400 amp hours worth of battery alive under moderate usage? I realize I"ll have to rely on my generator for AC usage, but the outlets in my RV will have plenty of juice. The charge controller that comes with the kit will be sufficient to keep my batteries in good condition during storage, and during use? Would I have any need for the following?:

    As I understand it, that is really only good for charging the batteries while hooked up to AC, correct? As I understand it now, I wouldn't have any need for that with solar panels and a charge converter, no? Unless I'm running heavy loads in the evening, and have access to shore power. Thanks for your patience, as I'm just starting to understand how this whole system works.
  • My truck, Nedeke Luka does not have:

    -- A generator, or,
    -- Propane.

    It does have:

    -- Induction cooktop/convection microwave
    -- Air conditioner
    -- Fans

    These are powered by:

    -- 600w of solar
    -- 250A of alternators

    Charging:

    -- 600Ah of AGM batteries

    If I can do it, so can you. My favorite oracles are:

    -- Handy Bob: Handy Bob and
    -- AM Solar: AM Solar - the company that sold my solar kit.

    Not all of this will apply to your situation but it is possible to get much better solar/battery performance than many people realize.

    And no, I don't plug in at campsites.
  • These posters are heads and tails above what I can offer..but that never slowed me down...I am just asking that whatever you do install you can remove. Your new-to-you unit is on the 'older' side. Don't spend a whole whack of change on something that you can't take with you when you leave. Solar is lots of bucks so be wise as you make your changes.

    I recently installed a Renogy system I bought from Amazon just like you had in your link, except it was the system with only one 100 watt panel, same controller. We boondocked for two weeks and were parked in partial shade most of the time and it did a reasonable job of keeping our batteries up (we have two 12 volts). I was pleased how well it did and frankly a little surprised but it obviously needed a little more juice because of our amount of use.

    So, I have on order another panel and will add it next week, giving me 200 watts total. With that, we can boondock in partial shade and stay charged just fine, based on our experience with the one panel. The controller is criticized on the Amazon site by some buyers. All I can say is it worked just fine for me. The main criticism is that the wires don't stay tight in the controller. The screw that tightens the wire in each entry point operates a gate type slide which closes on the wire. I suspect many people are just sticking in the wire and turning the screw and may in fact not be securing the wire properly because they didn't have it all the way into the gate before turning the screw. Examine it closely under a good light before you wire it up and you will instantly see what I mean and I don't think it is a problem.

    Good to hear you had a positive experience with it! We won't be running TV's or microwaves. Just outlets and water pumps, and such. You have 2- 12v batteries...can I assume that's more power than me getting 2 deep cycle 6v batteries?
