    Get a better heat pump that doesn’t need aux heat? I know Mitsu “hyper heat” minisplits advertise high efficiency to -10F.

    Powerwalls are overpriced for their capacity. Grid storage operators pay ~$150/kwh for batteries, then I’d guess about the same for charging/inverter electronics. I also see EV West sells 3.5kwh Samsung batteries to average consumers for $700 (I’m sure they’re charging a large markup as well).

      Are you going to buy me a new heat pump?

      Also why doesn’t anyone make a hyper efficient central system? I’ve only seen those hyper efficient units as mini splits.

      Are you going to replace my 2016 Sonata I spent $13k on buying in 2018 with a $55k EV with car to grid for me?

      What happens if it’s dark and cold for multiple days? I just can’t drive because my car emptied out running my minisplits?

        Lol. Was just offering suggestions you may have not known about. Off-grid isn’t practical for many people who aren’t willing make sacrifices just for the sake of it. Some people like the challenge and lifestyle. Renewable power plants are more efficient than residential. I think used Leafs can be pretty cheap, and even new EVs, solar panels (grid-tied), and more efficient appliances can save you money in the long run. Not sure if it makes sense to sell EV charge back to the grid (I guess it does if the price is right).

        I’ve heard of some people on certain electricity plans overheat or overcool their house when electricity is cheap to save money (acting kinda like storage for when electricity is more expensive).
