Battery not dropping below 30%

[CaptainKangaroo]

Looking for ideas as to why my battery will not go below 30%.

When it get to about 30-35% is starts charging from the grid at about 850w until it reaches 40-45% and then it takes over running the house again until it gets to 30-35% again and the cycle continues.

My SoC is set to 15% and temps are about 13-15c so not exactly cold.

Any clues?

It's an old thread, but it's likely due to the temperature being low, as a cold battery will do a lot of maintenance charges
