The Z-amp connection installed from the factory was meant to go with the Z-amp panels. If the Z-amp panels where purchased it would include a charger controller. I find that the Z-amp system is expensive and not enough watts. What surprised me the most was the very small wiring that ran from the Z-amp connector to the battery (#16ga). Even thought the amps being carried are relatively small, the goal is to try reduce, as much as possible, any voltage drops in the wiring/connectors. 10ths of a volt can make a difference in a battery. I rewired everything with #10ga wire.
I get a hoot out of getting power from sunlight, but it certainly was not free. I think that I have about $500.00 in the entire set-up. For me and the DW not worrying about finding a campsite with electric is priceless.
