A1. I have two 2512iX Controlers and like them, no problems, pretty easy to set-up. I also buy the IPN-Pro remote
with it so I could monitor
the batteries/solar input better which has been helpful even with the other monitor/gauges already on board.
A2. Yes I suppose you could - or use the Aux load
A3. I don't think you could.
I would give Blue Sky a call and ask for an Application Engineer
, I spoke to one at the boat
show last year and he was helpful and knowledgeable. They should be able to give you much better answers for Q2&3.
