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 ...

40 to 50 amp hours out of a 150 amp hour battery is 66 to 70% SOC. Portable, aimable panels up your amperage take over more hours per day. Another observation is that when I run 15.0V out of my charge controller to that T -1275, the charge controller seems to stay in bulk mode and at higher overall amps going in to the battery, in pulse charge mode.
I mention this because one of the charge controllers I have, while adjustable for voltage, really drops off on the amps it provides 66-75% of the time, with it's pulse charging algorithm. The solar 30 Amp charge controller I bought, for $33 off of Ebay, is much, much better in terms of keeping the amps up and pushing from my 120 watt portable solar panel, capable of 6.6 to 7 amp hours... 6.5. 6.33 6.28 6.5.... The 10 amp unit I bought drops off to 3 or 4 amps. Easy to measure when you put a little $15 RC battery charger meter in line and take a look at the output. Not all solar charge controllers are worthy. This is important on cloudy days and when counting on your solar panels to keep you off the generator as much as possible.
