battery performance testing

Post by briac »

hi,
I have an surprise on my battery performance testing:
at the first time I power off the panel I have about 24.64 VDC on the batt;
then after 30 mn the value increase to 24.96;

but somewere in another place it is the opposite.

do someone have an explination about that?

thanks by advance,
Leo

maybe the charging voltage is bad and only charging at 24.64
the FA panel should charge around 26-27 volts.
when you remove power the batteries should be around that voltage at least for a few minutes even if the batteries are going bad.
