Are you thinking about "RVing with SOLAR"? Are you in the planning stages? Have not decided on which SOLAR Charge Controller to purchase? Reason to switch? PWM? MPPT?
Here is an EXCELLENT VIDEO that will break down the difference and the benefits of one over the other. At the end of the VIDEO it mentions which unit they recommend for RV's and why.
They use 100 watt panels for the VIDEO, so if you are planning a 200 Watt system their output x2, 300 watt system their output x3..... you can then multiply your numbers * 5(hours of good sun) = Ah going into your batteries each sunny day. Calculate the difference, it adds up.
