float voltage
I am dealing with AGm batteries that have a suggested float of between 13.5 and 13.8 What may happen if they are only 'fed' at 13.2 for a float voltage via solar panels during storage? The solar sy...

This is a solar float when it is night more than it is daytime and when daytime isn't sunny so much (Nov-Mar) So the set voltage will be reached sometime some days but Vbatt usually will be lower than that on average.
In storage, my Morningstar controller goes into absorption for a few minutes every morning and it pushes 14.4V at the banks, followed by a float of 13.6V (all of this temp compensated). If I check voltage at 7:00 PM in the Winter it will be around 13.6--13.8V. If I check it in the morning before the sun comes up, it will be close to 13.6, the float voltage I'm aiming for. This is all with no use and no loads on the banks. I have battery alarms and no other parasitic draws. It's definitely a balancing act.
