Solar Charge Controller
Looking at solar and seeing different options for controllers. What's the difference between PWM and MPPT?

My twin 245w set ups are only different in that one has a 25 ft set of 10 awg cables, the other fifty feet. The system with the longer cables is always a few 10ths of a amp lower than the shorter. Worth it because the longer set up is easier to avoid the shade with.

Every rig/user is different so it's hard to say this will be enough. We used a 230w system last year for the loads you are talking plus a considerable amount of furnace run time. It was overkill even with the afternoon storms we had except for one cold and cloudy weekend, and even then it kept us off the generator.
Some of the places have 200w kits for $300 including shipping. I would toss the mounting hardware, hinge the panels and run the cable to the controller near the batteries. A little more work than the premade portables and twice the power.
