I’ll note that right now, this is a seasonal issue, associated with moderate springtime temperatures when there is a lot of sunshine available.

      I have batteries that I use for my solar - but here in the UK electricity pricing frequently goes negative in the winter at night to due to a surplus of wind power. a few simple automations make sure when that happens my batteries start charging and my electric water tank heater turns on. My energy company now has a scheme where they will do it all for you if you opt in - automagically getting your batteries to charge when it makes financial sense for you.
