My RE system: Flexpower one 24 volt

Total novice mayday

Post by 4310camelrockroad »

Would love to get chatty later but took the plunge and jumped off grid. More later.
Flexpower one 24 volt system is over charging my batteries and I will be damned if I
can figure it out. Checked every resource I have and web to no avail and thought I would
join this forum to keep knowledgeable in regard to this great product.

Mr Raysun caught my eye quickly as very knowledgeable and maybe could help me out?
Thanks guys and hopefully get to know you later.

@raysun will need to know the details of your battery charging settings for your CC(s), battery info and battery bank info, PV array setup.

Go for it @raysun. :grin:

Also are you truly off grid or have grid power and simply choose not to use it?
