Misread Trojan Battery Manual
All this time I thought the float voltage for Trojan batts was 13.5V but it's actually 13.2V. I misread the float for VRLA's and wets. Looks like I've been overdoing it by quite a bit. Trojan Batt ...

I like the "tips on how to maximize your battery life" at the bottom:As a general rule of thumb, the total amps from your PV panels should be sized between 10% and 20% of the total amp-hours (Ah) of the battery pack.
I deliberately lowered my battery capacity so that my solar can just barely reach 10%.
198 watts for a 130 A/h battery
I've taken some minor grief here and there on this forum for employing this strategy.
So a 210 amp 6v pair of GC-2's should get between 21 and 42 amp/hours capacity from the solar panels, for the day, if I am reading that correctly? I get 6.5 to 7 amps/hour at as close to 15.0V as I can for a Trojan T -1275... and 50% of a 150 amp hr battery is 75 amps to be replaced max, per day. No way I am going to get that kind of output come short days of winter and the sun low on the horizon. Summer time, yes.
