Hi Folks,
Set your budget. Spend as much as you can afford on the controller that has the features you want. Design the system to meet your needs. What works for BFL13 would not be suitable for me.
I'm now full time--and I wish to at least double the wattage. That probably means much as I love the Rogue that it is too small, as I am unwilling to reconfigure to a 24 volt battery system.
PT, I keep saying, you can use two controllers. You can have two separate arrays each with its own controller, to the same or different battery banks. You can put a Y at the battery end of the wires from the one big array and put a controller on each leg of the Y.
The last is trickier since you don't know for sure how many amps are on each leg, but the total amps comes out the same.
However you do it, you don't need one controller that has enough capacity for the one big array where that one controller costs kabillions and the two smaller ones are cheap---especially if you already have one of them!
