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

I live off grid in a tiny house and have built and rebuilt my power system several times, currently on version 3.0. My current system is 200W of PV panels, Morningstar Sunsaver MPPT, 240 AH of batteries. My lifestyle is simple, but I have power for pretty much anything I want to run.
My suggestion is to skimp on panels and spend your money on MPPT charge controller instead. In fact with limited space on the roof of an RV I would say that MPPT should be the norm. You will harvest more energy per day with an MPPT charge controller than a PWM version. Yes its more money but its worth it IMO. Wait until the first cloudy day and you still are able to harvest a respectable amount of power!
