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

I'm in a similar situation. I currently have a 100w Renogy portable with the 10a ViewStar controller mounted on it. I plan to get a second Renogy portable without the controller, remove the panel mounted controller and mount near the batteries, then use longer cables from the panel(s) to the controller. The ViewStar has an LCD display, is programmable and I set it for the Trojan T-105 specs. I have been looking for a 20a controller for when I get the second portable. The ViewStar 20a is out of stock and other 15 or 20a PWM controllers I look at, like Morningstar, are not programmable and cost about 3 times as much. I won't be getting a 2nd panel until next summer so I have time and can use the ViewStar until then, and maybe Renogy will have the ViewStar 20a by then.
