Charging GC2 with Rogue MPPT Solar
Charging a pair of USB2000 golf carts with the Rogue MPPT 3048. US battery says the absorb voltage should be 14.7V (for 2 GC2 in series) held for 2-3 hrs, with charge terminated by max time or when...

Well, Ontario isn't exactly Arizona. With 30A controller and ~450W you'll get 20-40 AH on a dark day, depends how "dark". It's still possible to get to Absorb, if - I hope BFL13 doesn't read this :) - you are trying to conserve energy. LED lights, efficient TV set. No 110V devices other than TV - at least, on a day like this. I hope you've maxed your solar up and didn't install a small 200-280W array.
Temperature default point is 25C, not 20C. It starts reducing the voltage when temps are higher than 25C.
Mostly everything is VDC (including the TV, but we haven't been using it), except my morning coffee grind. Lights are LED. Biggest draw is probably the 12VDC internet antenna amp ... it gets hot, and the computers. My wife is still working, so this is a "working holiday".
The panels are 2x195W in parallel (Voc 44V). Maybe we'll have more someday. There's a lot of energy up there just going to waste.:)
