More Solar for "Us"
Ok, I went off.the deep end? Bought 3 used 37watt uni-solar panels and a blue sky 2000e controller for the hefty price of $400, They were being listed as 75w panels, they are not The tested open...

Afaik this is true of all solar controllers, even the Grape 40
Granted as load is applied and amps increase voltage drops and there will be an increase in solar amps output
But the previous controller xantrex did not change anything
Correction: voltage doesn't always drop. It will drop when the incoming amps are not enough to keep it where you want it, and until this happens - due to higher loads or low sun - voltage won't drop.
Controller (any controller, IMO) would cut the excess solar amps off when battery or loads don't demand amps (subject to setpoints). And it would increase the amps when demand increases. Maybe you got a faulty Xantrex, because what you described doesn't sound normal to me.
