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

So the link I posted to the kit is decent?
Expensive for a single 100 in the States? But the "free shipping" cost is in there, say $50 worth? It depends whether you can pick up a set yourself from an "outlet" near enough to where you live for less money.
I tried a single 130 as a portable that I kept mostly aimed at the sun during the day, sort of tracking. Not quite enough solar for us. 230w tracking like that is pretty close. Tried 360w for a while but it was too much solar for our needs.
You have to know roughly what you will need. If you don't have that info yet, starting with a 100 and adding another later if needed is a good approach. That 30a controller is there for that approach.
But sometimes it costs more to do it piecemeal with shipping etc. Sometimes pairs of 12v panels come on sale.
