Not Discharginging Batteries Enough at Night?
I have a dedicated solar array that just runs my refrigerator/freezer. I run a log of battery voltage every night, and of course it looks a lot like a square wave when graphed each morning. With a higher flat when the battery is at rest and the lower flats when under load by the refrigerator. My concern is that the final at rest portion in the morning before the panels get sun and start everything climbing back up is never less that about 24.9V. I am worried that it is unhealthy to just lightly discharge the batteries like this. Do you think I should add a further load to this thing? I guess this might work in my favor as the batteries age. The system has only been in service a few months. But still I wonder if I am harming them now?
