Btw, if Rogue MPPT 20 is still available, with their remote interface it's a better choice (for the same price) than Morningstar MPPT 15. Or without remote.
On a brief glance, it's a downscaled MPPT 30, all the same features except for remote voltage sense wire. Adjustability is unbelievable, MS 15 doesn't even come close. I only saw something like this on expensive 45-60A controllers. Absorption stage is time-based or automated current-based, and either parameter is adjustable. Their remote interface is a real "interface", not just a meter, you can both see and change anything from there.
