I have the Morningstar MPPT-15. One of the better aspects of the controller is that a user can define all of the stage voltages and the duration of them. It is all done through the MS software and fairly intuitive, just select what you want and save that profile. It makes a lot of sense for storage situations.
that is one of the things I really like about the morningstar. I did similar based on our typical useage.
But with my panels I can get the morningstar to limit at 15A on sunny days with my panels, 3 80W panels. A 20A controller would be nice.
But previously the step UP to a bigger controller really was a big gulp to swallow in $$$$$$.
Outback 20A, Morningstar 15A, similar price = fast decision
