I live off grid, and have more than my batteries can take. I considered just doing a hot water cylinder for the excess, but I’m currently instead working on a hot water cylinder heated by GPUs. May as well do some useful work while making my shower hot.

Was thinking about this too. Or mining Bitcoin and using that wate heat etc. There's heat pump boilers apparently with some additional loops for external heating (meant for solar water heaters) that could be used for this.
