Help! Bogart Solar Controller Overcharging
I have three 140w panels on the roof with a Bogart SC-2030 charge controller and a Trimetric monitor. Left the camper to go four wheeling and returned to see the batteries (Two group 31 AGM) chargi...

Battery temp of over 150f seems pretty warm. That should have reduced the voltages rather than increase them unless there is something wrong. Your P22 setting of 9 is a default settings for concord AGM batteries which should limit you to a max charge voltage of 16.5 volts. Personally I'd override that default and set it lower to protect your on board electronics which probably have a lower max voltage recommendation. I'd definitely wait to hear back from Bogart and discuss what might have gone wrong. If you get in the instructions you'll see how to check your P8 setting which is absolute max voltage.
For equalization, you use the select button to cycle through till DSE is displayed (Days since equalization). If the value is 0, hold select about 5 seconds and it will start equalization. If the number of days is greater than 0 hold select until is resets to 0, release, then hold again for 5 seconds and it will start equalization.
BFL13, Dekas low and slow isn't necessarily that slow, I probably made it sound worse than it is. They recommend 14.3 volts absorb without a high voltage finish, or mini equalization if you will. Only a couple tenths lower than Trojan. From what I've seen in the garage topping them off they charge up relatively fast given the voltage. I'll have to see how they work when I stuff them in the trailer. I'm also upgrading the solar to a fair bit of over capacity for only 460ah of battery. I'll have 1000 watts, 10*100 will all ten panels parallel wired since I camp in mixed shade quite often. I've had a lot of experience dealing with assorted batteries over the years, so if they aren't behaving as desired I'll figure out how to make them behave. Hopefully without blowing their tops in the process....
