Hello everyone, just finished upgrading to a 48V solar system for my off-grid home after running for the past two years on 24V. I have a mixture of 12V 300ah batteries, some are LiTime and some are CHINS. After completing the setup programming on the SP6548 boxes, sun was out and the batteries were doing well. I measured each of the 4 batteries in series... three were at 13.5V and fourth was reading at 17.5V. I nearly had a heart attack!
My guess is the BMS has failed, maybe partially? I thought the cutoff was 15V. Not sure. It's out of its 1 year warranty but still within the 5 years that CHINS says they will service it. I guess for some huge amount of money?
What are my options on this one? Continue to use it but monitor the system closely? Or will I have to move it to the experiment pile and salvage some of the parts?
Thanks.
