Battery Systems

[Capn Buck]

I have yet to ascertain whether it is better to keep your battery bank fully charged all the time (via solar panels or battery charger if on shore power) or allow your batteries to discharge (say overnight) before recharging them the next day? Any comments will be gratefully received

Battery bank will last longer if you keep them topped off.

Fridge will drain your battery bank over night, then solar panels will bring them up to full before noon and keep them full until sundown and then start all over.

Welcome to the forum. Capn.
Keep them fully charged.
If they are on float for a long time a slight discharge and recharge very occasionally can be helpful. If on float for a long time consider slightly lowering the float voltage and an occasional equalization charge (if the battery chemistry permits) is beneficial,

The less amp hrs that you pull out will give you more charge discharge cycles over the life of your batteries. I typically bring my batteries back to FULL charge once a day, none of that 80% stuff for me. It does cost more to keep them happy.
