I find it so strange that when returning excess PV power, more (about double that of L1 and L3) is always supplied to L2. Does anyone have any idea why this is?
Is there also a way to prevent feeding back from the battery when it goes from absorption to float? Currently, about 2% SOC disappears after a full charge. I have a LifePO4 battery with a JK V19 BMS. The best thing would be for it to remain at 100% and also maintain the corresponding voltage, reducing it as demand from the batteries increases. If the voltage is then around the float setting, it can remain there if PV power becomes available again.
Thanks!
