More on those overnight "blips" of charge to the battery
I seem to have stumbled upon something pertaining to this issue. On my system both Grid Start and Low Batt were set to 25%. I changed my System Mode timetable so that I only discharge to 30% under most circumstances because I was not sure that these "blips" were a good thing for the battery. Doing that stopped the behaviour. I have changed Grid Start and Low Batt to 23% and 26% respectively and when I let he battery sag to 26% it seems to get a boost from the grid. So, I think that my prior post that it was the Grid Start setting that determined this behaviour was wrong. I believe that it could be the Low Batt setting. I had wrongly thought that this was related to a warning notification. Can anyone confirm or refute this? I find it so easy to assume that I know what a setting does in the absence of hard information! Does anyone know what Grid Start actually does? I saw another post that said that it does not exist in the settings screens on the panel itself.
Ok, I found the solution.
In the Battery settings the Batt Low was the same as the min SOC in the Advanced settings. Ater I changed the Batt Low Setting to 20% the Blips are gone.
