Capacity Testing and 20 HR Rating
I'm thinking about doing a capacity test on my four GC2's. They have a 20hr rating of 215Ah. One thing I'm curious about is how the 20hr rating would have been determined. Being 6v, would they h...

Mex,
This is the dilemma I find myself in. When working 9 hr days, mon-thurs, I may or may not be able to run out to the bus and either turn off, or lower the voltage on solar charging. (And quite frankly, I don't want to have to plan my days off around battery charging, either.) So if daily usage is such that the bank is full around mid-day, it will continue to 'float' at 14.4++ volts for several hours (using the solar30 pwm). My thought was to drag out solar charging, by using just one panel (140w) instead of two (280w), at such times. But either way, the bank will be in that high 14's range most of the day. So I'm wondering if there is a suitable 12v timer that could be set to disconnect panel power to the controller? Or is it not worth worrying about?
Of course, my other option is to simply fore-go the solar30, and use the programmable tracer mppt, which should drop into real float when near full.
