AC Coupling with a Schneider SW2524

CleverJay

I have an off-grid system with two 1600W strings going through two Outback FM60s feeding25KWH of 24V EG4 batteries with a Schneider SW 2524 Inverter. I would like to add another 1600W (eventually 3200W) AC coupled string using Homiles microinverters @240V. The Schneider documentation seems to want you to tie the AC coupled string to the Load side of the inverter, this seems counter-intuitive to me. Why can't or shouldn't I add the AC coupled String to the AC input side of the inverter, with a transfer switch for my generator?

You need to read more on how AC coupling works, Schneider docs are right on this. Using the outback cc's is a mistake for ac coupling with a CSW 2524, no way to throttle back out of network fm60's. 

I think it is foolish to do what you are proposing offgrid. My opinion.  Asking for trouble?
