I have 12 LifePower4 batteries connected to my 18 kpv.
I have 1 to 1 net metering, so I only draw these down to 85% on a daily basis.
In the AM, on a sunny day, I get to 100% soc pretty quickly.
One odd behavior I am seeing is, throughout the day, for a few minutes at a time, there will be current flowing to the batteries, a few thousand watts. Then all goes back to normal.
I am ASSUMING that this is a result of the cells leveling out, and some more "room" for energy being found, i.e. some cells might be a touch below the majority in a pack, and when it all smooths out, there is more room for some juice. (these are technical terms
)
It's not a problem per se, more of a curiosity.
