I have a Midnight The Kid Charge controller hooked up to 4 6v Interstate batteries as a 12v system. I am using a shunt with the wiz bang jr. I also have a temp senor on the batteries. I have the Battery info added to the Charge controller. Batteries are stored in a room temperature environment 100% of the time.
I do not use the battery bank for anything currently other than on demand backup.
In my mind if it gets a full charge during the day and doesn't use any of it's power, the next day should only need maybe a trickle charge. Instead it goes through a complete charging cycle.
Example; Complete charge day one. Sun comes up day two and bulk charge has started charging at 15-20 amps for like 3hrs. You can hear bubbles and it vents the hydrogen. During the charge controller cycle it seems to spend very little time in absorb and float, and most of the time in Bulk.
After a few weeks of this I will need to add water. After a day of charging if i disconnect the panels and let things settle like over night I can measure the battery bank and it will read 12.7 -12.8 with a multi-meter. This voltage will remain the same for days. So I cant figure out why my charge controller seems to think it needs to do a charge cycle again if the batteries are full.
Thank you so much for any help or advice you can give.
