You will start by deciding weather you want to wire your batteries in series or in parallel.

In series the batteries are connected end to end forming a single path for current path.

In parallel the batteries are connected all components are connected across each other forming two points of electrically common points.

Next, you'll wire the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D with your batteries and your solar panels as shown in the attached images.

Personally, wiring your solar in parallel is the best option because it will allow you to have more solar panels without exceeding the inverters voltage limit.

Also, when wiring in series, every device must function for the circuit to be complete. If one goes out, the whole circuit is broken. While, when wired in parallel, each panel has its own circuit. so one could go out and the circuit would still function.
