Battery uses power to keep them charged at 100% in ESS

I have a Victron Easysolar 5kv with Pylontech 2000 battery... I keep batteries charged to 100% and only use them when grid fails. I see this uses about 15% of my solar yield... is this normal and is there a fix?

That’s probably normal. See mine below.

In ESS systems, due to the way ESS works, small currents flow from battery to AC and vice versa, nothing strange.

Where do you see that? Please share details / screenshot.

Depending on what solar yield is, and if it is small compared with the batteries, this is certainly possible.
