I need a solar charge controller for a mobile platform. It will be on a small boat (less than 8 feet) in the ocean so it will rock a lot. It will have a 100W 12V solar panel and I plan to have an 80 amp load (not all the time, but it needs to be able to handle at least that much). Now I know most solar charge controllers have connections for 1) the solar panel, 2) the storage battery, and 3) the load. Is the only reason you would attach the load to the charge controller is so that you could cut-off the battery when the charge gets to low? If that's all, it would be cheaper for me to get a 10A controller and attach the load directly to the battery? Or will that cause other issues as well.
Also, what I've read is that MPPT's are worth it for higher voltage systems. Since I'm just having a single 100W panel at 12V, I'm thinking I would get a PWM module. Does this make sense with all the above?
If you can answer one or both of my questions I would be grateful for the input.
