Hello. I have the MPPT 100/30 controller and a BMV-712 monitor. I'm running 2 x 12v 125 amp/hour batteries for a total capacity of 250 ah. About 11 days ago, according to my app, my battery voltage started dropping and has not reached absorb or float voltages. Before this happened, I was able to go several days in my van/RV with my average daily loads. Now, the batteries never get above about 12.6 volts, even after great sun all day on my 200W solar system. I'm not sure what happened or why. Does anyone have any ideas? Thanks in advance!
