You can’t “disconnect” completely like you said, but say a power outage or during peak rate times (5-9 pm where I live) you can switch your system to using the batteries only. Pretty common set up/software that installers out here do all the time.I would have done geothermal but it was impractical in our area. I know climate is a hoax b/c geothermal would be the standard and heavily subsidized if we were serious about reducing carbon footprints.
My understanding is you can't disconnect from the utility and have to shut yours down when power is down so you aren't backfilling the grid when it is worked on. There was a case in Florida a number of years ago where the guy wanted to disconnect and the town insisted on condemning the house if it was not hooked up to the power grid. Totally defeats the most important use case IMO - power when the grid is down. Just the process of a power diverter for generator use is a massive PIA. Cities really promote dependency. It is not cost effective on its own and without disaster planning to validate the cost I just don't get it.
I could get behind an EV for local use but refuse the concept for longer distances. I am thinking of putting a fake plug on my truck so I can park in the EV spots all over town. Rare earth metals mined by 6 year olds aside - lots of nice luxury, performance vehicles are EV only. Been a number of fires at the beach from EVs not playing well with the salty sea spray air.
Maybe the use of the phrase “off grid” is inaccurate in this case?
Anyhow, if the system is designed correctly you’ll never pay for power per se. In my specific case I think there will still be a small monthly charge for the meter just being there albeit running backwards so to speak which I believe I receive a credit for and we would definitely still have power during an outage.
I’ve never personally seen an EV on fire but have seen a number of vehicles with internal combustion engines in flames (insert libtard run city joke here).

Yeah, they mentioned at the end of the article that the battery could last 20 years AFTER they already established that only the very elite EV batteries were going 20 years. Unless that 2019 EV you bought is a Tesla or one of those Lucid Air type vehicles with liquid cooling for the battery, it's likely not going 20 years.
