Hi,
in the past I was wondering, why my SoC was falling 1% every 1.5 hours when minimum SoC was reached. The reason was peak shaving being activated always. I’ve changed this to “only above minimum SoC”, but now I have the problem, that when ESS is discharging and minimum SoC is reached, it will start charging immediately with around 400W slowly dropping to 0W. Unfortunately after a few seconds, SoC will go up by 1% and discharging again starts. After a few seconds it is falling again by 1% and charing immediately starts. As a work around I added a function to Node Red which sets peak shaving to always on when SoC is above minimum SoC, to “only above minimum SoC” when SoC is below minimum SoC and when SoC reaches minimum SoC it will change it to “only above minimum SoC” with 2 minutes delay. This seems to fix the issue.
Maybe this is only an issue with Pylontech, but hopefully Victron can change this behavior in their software with some hysteresis or delay.
