    Also in the winter time you have 1X or less power so where do you charge your EV??? also EVs use more power in winter to heat, defrost etc.
    not everyone can drive less in winter??
    off grid people are often not near public chargers as well.
    If you're off-grid and in the position that you describe.... would it not still make more sense to have an EV that you could use to soak up extra kWh in the spring and fall? Even if you occasionally need to run a generator to charge an EV you'd need to use gas or diesel 100% of the time if you don't have an EV. Or... just get a volt and have the best of both worlds

      Is that not on the books for CA?
      Yeah, I don't know how many have been installed under the Self Generation Incentive Program. They have gone through millions in funds and I think reduced compensation is still available. The incentives include Investment Tax Credit. Many Tesla Powerwalls were installed that way for a net cost of $4,000 during step one of the program. Globally I think at last count Tesla has sold 50,000 powerwalls and LG Chem, Sonnen, and Enphase have products for that market.
      EDIT:
      Here is a link with more data.The total is 2 gigaWatts. I had forgotten that a number of large systems were also incentivized by the program.

        Running a generator to charge and EV or charging and EV from battery is very inefficient and a lot of battery cycling.
        You would be spending more on fuel, batteries, and vehicle and most likely solar

        A plug in hybrid is different from an EV

            Less fuel overall since using diesel in a generator to charge an EV is actually more efficient than burning diesel directly in an ICE. ICE is pathetically inefficient, ICE in a car even more so since it's rarely operating at its ideal RPM like a generator. AND you obviously wouldn't always be charging off a generator...
