I can’t wait for this to be available at similar prices for a single family home. Add in solar and a relatively small propane powered backup generator (harbor freight) for extended outages, and for $15k I could be completely off grid. Yes this could be implemented at the grid level, but when it’s at my house, I can crank my AC as low as I want whenever I want. Living in AZ, that’s a massive selling point. The disruption is about to be huge. If everyone in Phoenix suddenly goes off-grid, the power company is going to be stuck with a massive capital investment it can’t pay back. Unfortunately my power company is also my water company, and they will likely just crank water rates. Can’t ever get away from paying the man.
