SOC no longer going below 40% in ESS

Hi,

since a few days,I recognized that my MPII (cerbo + 3xUS3000) does not discharge the battery below 40% even the battery was charged during the day to 100%.

I cannot remember that I changed any settings but I had installed the v2.62~4 and v2.62~5, but went back to 2.60.


Does anybody can help?

Hi @hansbaer,


Your site appears to operate correctly. In the last 14 days you only had 3 good days where the SOC reached high enough to decrement the ESS BatteryLife MinSoc, and 2 days where it was kept the same.

The minimum will only go down by a 5% increment on a good day. Since it has reached a high point of 55%, it will take at least a few more days to get back to the lower level.
