I don’t put power onto the grid. My state doesn’t do net metering. Basically, if I were to put power onto the grid I’d automatically be signed up onto their solar buyback program, which would require me to pay a large monthly fee just for them to buy power from me for a tiny rate. No thanks. Thus I set my inverter to never put power onto the grid even the 3.3 hours I average per day in which my solar batteries are fully charged and I have extra power looking for somewhere useful to go.
You my consider getting an extra electric water heater and dumping the excess energy into it.🤔
