Solar Question
This is not a RV application but there seems to be a lot of solar knowledge on here so I thought I would ask. I run a 12V system in my remote cabin for LED lights and RV size water pump and CD play...

FWIW, I left an AGM, partially charged battery, to over-winter in unheated space in MN. After 5 months it measured 12.4 V. I know I wasn't doing it any favors and treat my cells a lot better, now, but the amount of puny discharge was surprising.
Their full 100% charge is 12.8-12.9, as you probably know. 12.4 is around 50% or less. A new AGM would lose about 3% a month at room temps, or less when it's colder.
