New to Solar, question about batteries (40A Rover)

Hi guy's. I'm very new with this kind of things. I've just bought a 200w panel kit with Rover 40A controller for my caravan. I need some help with the batteries ( how many batteries I can use, or what's the best choice to configure this kit). Also I have no idea what brand and type of batteries I need to use.amd if need something else to install it. Thank you guys and I hope you will help me.

Caravan as in a car?? If so I would but the best 12v deep cycle battery you can afford... What are you wanting to run off of the solar system??

No, caravan as a trailer caravan.

And I want to mount an inverter for a fridge

4 6v deep cycle batteries or 2 12v the best you can afford.... That's the most I would get for a 40a CC.......

I suggest you read up on 12VDC systems for RVs and trailers. Some great stuff on You Tube but beware, some bad stuff too. I've recently installed a Renogy system on my travel trailer that is working quite well.

What brand model caravan (travel trailer) do you have.

Beware of you tube as most of it is total BS..... That's what got me down the wrong road in the first place when I was putting together my first system...

And yes be sure and read up on 12v systems... You might come to the same conclusion as I did.... They suck.... Why do you think that campers, travel trailers have a AC hook up? Have you ever pondered on that?

I'm new to forum.

Just installed Renogy 100 watt panels and Rover 40 amp MPPT controller, connected to 2 6V deep cells, in a 2012 Roadtrek Popular 190, on 2011 Chev 3500 Van chassis. Roadterk has original Roadtrek factory installed AC/DC charger/converter/inverter system. Seems to be working fine. The purpose for the solar is primarily to top off and provide back-up, when of-grid boondocking.

My question is, now with the solar panels and 2nd controller (Renogy Rover 40 amp MPPT) also connected to the batteries, will connecting the original 120V land line at home for primary battery charging, or charging of the batteries from the Chev engine alternator while driving cause any feedback to the Renogy Rover 40 MPPT, that may damage system, and thus require disconnecting the solar system, when charging batteries from the other more typical sources?

I don't think I would charge the batteries with solar when the AC is hooked up..... There is no need because the CC will lower the voltage when the batteries are charged...

oldfosester, there is no problem having multilple charge sources. Never disconnect your solar, compatible with alternator and shore power charging.
Solar makes a great maintainer in storage.

maybe the OP could add or restate another question.

No need to do that.... This thread has mixed post plus he would get the same answer in a new thread as in this thread....

tatoo, then maybe you could explain what other question about AC?

Thanks, for the replies, and the reassurance that Rover can handle multiple sources, both AC and DC. I thought I had read that somewhere in the materials, when I was researching various options for controllers; but when I went back to check, I could not find that reference to verify it.
I appreciate the quick responses.
