Hi @ all
Today, I suddenly noticed a pretty nasty loud beep from the basement. One of the Pylontech US2000C batteries beeped loud. The Cerbo GX shows an "internal failure" and the master battery of the set of 8 batteries shows a red light.
Does somebody know what that means? What do I have to do? SOC of the system is 61%. Lowest and highest cell voltare seem fine (3,301V / 3,315V). Not much solar but the system was working well .. active soc is 65% due to bad weather. I saw it reached 65% shortly then went down to 61%.
What am I expected to do? Switch off all batteries and restart them? Will that interrupt the power supply of the inverters? This is a first for me ... the batteries are just 6 months old.
Best Regards
