House/solar battery opinions
My current battery space is 20"L x 14"w x 10"H Going solar, and want to packs as much AH in there as I can (reasonably). Currently looking at 250 - 300. Price is not THE deciding factor, unless ...

No idea with MPPT and tracking confusion issues, but I did report on my success with parallel PWM controllers on one array on one battery bank.
In this case the question was whether you could put a Y in the array to controller wiring and have one controller on each leg of the Y. The controllers have their own controller -battery wires to the same battery.
It worked just fine. I was not able to measure how many amps of the total each controller did, but it would not be half each unless the Y were perfectly even for R.
You don't need two separate array-controller sets of wires iaw. You can put the Y close to the controllers and save a bunch of wire.
The reason for that set-up was that each controller was under-sized for the total amps of the array, but the two controllers sharing kept each under its rating. Worked great.
