If you do keep them separate, the 20 amp EPever is probably fine.

You could also hook them up to the same battery bank (both controllers at once) and that won't mess anything up.

Yes, those are pretty standard for wiring two panels in parallel on a small setup like yours.



Grounding is in reference to what battery terminal is tied to 'ground'. Most vehicles, trailers, etc. are ALL negative ground. There's not been one in quite a while that's been positive ground, that I know of.

For example, negative ground would be where the frame of the vehicle / trailer, is tied to the negative terminal of the battery.

Likewise, positive ground is where the frame of the vehicle / trailer, is tied to the positive terminal of the battery. (This is VERY rare!)

You CAN use a positive ground controller (although not recommended) on a negative ground vehicle (or vice versa), just don't 'ground' anything of the solar system to the frame except where already done for the existing battery bank.


I'd specifically recommend this variety of controller:

You'll also want this guy, for config and monitoring:

You'll also probably want the battery temperature sensor here, and it comes with a cable for connecting it to a laptop for very specific config-tweaking, should you ever want to:

Thank you for the response :)

There’s a couple reasons why I wanted to keep them separate. My sister and her husband have a camper as well, and if they are separate systems I can borrow one out. Or use one to charge my electric canoe’s battery.

If I wanted to hook both up simultaneously to a single or double battery bank, would it damage it?

Also are these the norm for wiring in parallel? https://www.amazon.com/dp/B00Q26PC04/ref=sspa_mw_detail_3?psc=1

So if I do keep them separate I should look into a 20amp version of an EPever correct? I’ll have to do some research on the negative or positive ground for my camper. Is that referring to the grounding coming off the battery terminal? I’m assuming all RV batteries are grounded to the frame. Mine is being delivered from Iowa, so not here physically yet :(
