Installing new Xantrex RS3000

[sfedeli3]

Hi Michael,

Two years ago, I installed at ProSine 2.0 in the Rediline/charger
compartment. There was a 12/3 cable running up through grey plastic
conduit to the closet behind the bedroom. It took some silicone
grease, but I was able to pull the old rediline wire out and run 10/2
and the phone duplex cord for the ProSine's control panel up through
the same conduit and behind the 48" flourescent wall sconce in the
bedroom to the closet where the main breaker panel is located. I ended
up pulling 4 circuits out of the main panel and relocating them to a
smaller 30A sub panel in the closet behind the main breaker panel. The
110V supply for the charger side of the inverter was already routed to
a duplex outlet in the charger compartment. I seem to recall that
being 12/2 wire, and I've had no problems with the breaker tripping
when there is a 100A charge dumping into the batteries. You can
program the ProSine to know the size of the breaker.
