Hello all
I have 3 brand new 10KW powerwalls from a chinese company called youth-power. 2 of them will always charge to 100%, one will always stop at 99%.
These are connected in parallel to an 8KW DEYE hybrid inverter.
By mid day, the batteries reach 99% and it will stay there for next 4 hours until sunset.
If I remove that specific battery, the other 2 will go up to 100% in about 5 mins.

What are your thoughts on this?
