Yann,
I was just reading back through these messages and I can't  see how the situation with your batteries was resolved. Are
they ok now and you get enough pv power to keep them charged AND power your loads?

Hi dgd,

The battery voltage always jumps too rapidly and the Classic too rapidly thinks they are full

The batteries maker wants batteries desulfate by plugging a specific device (a battery regenerator) for 100 hours, next week.
But I need to find a three-phase connection, that's not standard in our homes.

Yann,

So they think the batteries need desulfated?   Have you ever seen those high frequency battery conditioners? They are usually
available at an electronics store or battery suppliers. They are supposed to 'recover' sulfated batteries and sometimes do a good
job. Usually about $50 to $80 and work 6v or 12V. Won't work on damaged battery where plates have corroded away.
