One other thing I wanted to point out about that Sun Saver MPPT. It has a MAX output load rating of 15amps. My camper has motor driven jacks. They draw almost 30amps when lifting the camper. Because of that, this controller would not work in most campers with motorized jacks.
Ummm? You wouldnt be driving them (jacks, or any other load) directly from solar output.
No. The controller has three connections;
Input (from solar panels)
Battery (the house battery plant)
Output or Load (the feed to the 12 volt buss that everything on 12 volts connects to)
The controller is rated at 15amps OUTPUT or LOAD. The jacks draw 30amps. Even though the batteries could handle that load, the jacks are not connected to the batteries, they are connected to the controller output.
The purpose of the controller output being separate and isolated from battery is mainly to disconnect load when the batteries get too low. This keeps the batteries from being damaged from being drawn too low.
Hope that makes sense.
