I am looking to upgrade my 160w/9.5A system to 640w/34A with possibility of expanding to 800w/40A in the future. My Blue sky 2512i isn't going to cut it, an easy pick would be the Solar Boost 50DL.
But... All the 50Ampish MPPT Charge controllers (Outback, Bluesky, Xantrex) run about $500, which one gives you the best bang for your buck, and or, is more reliable, etc? Thanks!
