I have done several systems where we just paralleled two batteries on the battery terminals, just like we'd do with lead acid batteries, with a reverse return for the home runs. With the active balancing, the reverse return is apparently not as important, but I still think it's best practice.
MidNite Power is working on a custom gutter/wiring box for coupling the PF16's directly to the AIO, but not sure on timeline for it. I've seen a few really nice installs where someone used a standard 10" gutter with cutouts in it directly on top of the PF16's, then set the AIO's on top of that. No exposed wiring or even conduit showing. Zeke -- Zeke Yewdall PV Engineer NABCEP #031508-89 [email protected] 303-523-3592
