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

We won't use it very often with rv. And will want to use at home as I mentioned.
Do you homework, read up what was suggested on the 1st or 2nd page.
Doesn't matter where you will use it. See what Niner Bikes said about controller - it has to have the features that you need. Also, cable length and gauge. You are trying to get useful tips, but without understanding certain things you're shooting blanks.
If 100W is all that you are going to have, then cable gauge is less important (up to a certain length), but controller still needs to be a decent one. I personally wouldn't be able to do a lot with 100W panel, even with my minimalists setup. This is the problem with portables - a small one would harvest too little (almost nothing on a dark day), and a big array would be a tedious logistics of setting up and breaking down, especially if you move often.
