Great topic @angusc. Welcome, glad you’ve found us, and that you have been reading along. We’ve been talking about this a lot recently. What you have described is the future as we see it, I was just writing about this situation here: > [@Should I get batteries with my solar?](https://perform.discoursehosting.net/t/should-i-get-batteries-with-my-solar/919/2): > > If you want to avoid SmartMeters and/or the overcharging of electrical usage by Utility companies by these Smartmeters, then off-grid is a solution to the problem, and batteries are a must. Expect to pay an additional $20k for the battery banks required to run your home. You will need gas furnace for heating though because an electric one will drain your batteries fast. Average house usage is 1500-1800 kWh a month, so size you solar array for such. About 60 panels (depending on watts per pan… I need to do some further research, I think @Svarky knows more, but my understanding is that some EVs already have the ability to send electricity back to the house (and grid) built in. Although the device you mention here seems like a winner too. Do you have a price for it? My only thoughts would be that perhaps you could do with more than 20 solar panels? Would any more fit on your roof? Although maybe that’s not such a ‘no brainer’ as it is in Australia due to fewer sunlight hours. Keen to hear more on this topic, and whether there are EVs with built in V2G capability. Cheers Marty --- _[View the full topic](https://forum.cleanenergyreviews.info/t/vehicle-to-grid-v2g/1499)._
