Frank, thank you for this info.
What you have is pretty much what I had in mind.
I have three 100 watt panels up already and wires there for three more panels which I have two more panels here in storage already still in poxes and two or three panels more to come maybe this or next month.
Did you use same brand/model PWM charge controller?
(
are in parallel my bank is 12 golf cart batteries wired in pairs and 2 4D all are connected at a single point ).......what is a 2 4D? are those your inverters?

Both Charge controllers are exact matches same brand , same model same size
4d is the size of the 2 12v batteries they are used mostly for starting heavy equipment or as starting batteries for medium sized 200 to 400 KW generators.
