[RE-wrenches] Outback FM100s not available

Friends:



I need three FM100 charge controllers but it seems no one has them.  It has
occurred to me that for not much more than the cost of 3 FM100s I can buy a
Fortress Envy 12K inverter and it will have the capability of 3 FM100s plus
12 kW of inverter plus compatibility with the existing Unigy battery bank
plus future compatibility with Lithium batteries.  The same applies for the
Sol-Arc, and the Midnight AIO and probably others.



Since my first Radio Shack separate amp and tuner, I have always favored a
component approach to systems.  With Outback apparently circling the drain
or generally being unavailable, I am starting the see the appeal of the new
AIO inverters.  The AIOs have a wide voltage range on the MPPT inputs
making stringing less problematic.



I ordered a Sol-Arc 12K for my property to load shift and solve my NEM3
dilemma.  With CTs on the service I can run my home on batteries from
sun-down to sun-up and avoid being screwed by PG&E.



It’s hard keeping up with all of the new technology but we are getting new
tools to solve design problems.
