I have a Solis hybride inverter since july, and added a second LV5200 battery last month.
I noticed during charging the leds on the batteries are not the same. The master battery indicaties...40 to 60%, the slave battery 60 to 80%.
As result, the Solis inverters jumps all of a sudden from 70 percent to 100% (after a sudden rise in battery voltage)
I suspect the 2 batteries are not in balance. Anybody any idea´s how to solve this?
Balancing several batteries
normally you fully charge and discharge them fully and then full again normally balances them

Hmmm....
Somehow when the batteries are empty (according Solis), I can see the main battery one led blinking, so between zero and 20%, but the other battery is between 20 and 40%.
Yesterday it jumped from 35% to 100% on Solis. And we discharged it completely over the night, it looks like we discharged almost 8 kWh?
It is a strange situation.

Have you tried a full empty to full cycle and restart the inverter when the battery is full and make sure the voltage and SOC are showing correctly?
