TC off the grid, and solar question

The original question:
Do I wire camper load (and not camper changer) to load terminal? or leave them empty? I expect by using load terminals I can view current amperage usage the RV is using on a display. And If its a 20A controller, that that mean the current between battery and Load is limited to 20A?

You connect the load side of the solar controller to your batteries with new wiring that you run between the controller and the batteries.

You don't rewire the camper and put all the loads to the solar controller, you just leave those wires as is and run new wire.
Load and the charger already present in your camper are hooked tot he battery - nothing changes there.

As far as what the meter on the solar controller is telling you, it will depend on what brand and model solar controller you are talking about, but generally speaking, it tells you what amount of current the solar is putting out to the batteries, because all it is doing is monitoring solar current. It doesn't monitor the amount of amperage that your camper is using. If you want to monitor what the camper is using, then you need another meter - like a Xantrex LinkLite of LinPro

If it is a controller with 2 separate battery connections (2 batteries) does it treat each battery different?
example, every 25 days it does a charge to knock sulfation off the plates, but a single 100w panel might not have enough current to run de-sulfation mode on 2 batteries at the same time.

I haven't seen a controller that had two output isolated from each other - they are parallel to each other, meaning they are "connected" internally (in the controller).

But, what make and model of controller are you referring to? Knowing that details, we can give a proper answer.
