I'm trying to understand the condition of our house battery bank. I'm definitely not a battery expert. We have the original Dolphin Battery Chargers (100A and 30A). We use the 30A at the dock and the 100A with the generator. We also have a Victron Blue Solar 100/30 with 630 watts of solar panels. The installer set it at 28.8V Absorption and 27.6V Float (Position 2).
First: The 12 Group 31 house batteries use about 0.5 gallons/month...is that excessive? I'm wondering if the MPPT controller is overcharging the batteries.
Second: How close to replacement are we?
Third: Should I just replace Battery #3?
