Automating Off-Grid-Mode to utilize Cybertruck battery power during peak hours?

[HawkDuncan]

Peak pricing for power in my area is 4-9pm. My understanding is that the Cybertruck with the PowerShare system can be manually triggered to disconnect from the grid and power the house from the truck battery.

All it would take is a software update allowing us to schedule Off Grid Mode so that we can power our homes from the truck during peak hours. Back of the napkin math for me suggests I could save around 2-3k per year doing this with my solar system.

Even if you dont have solar, you could save money charging your truck during cheaper hours, and then drawing from the truck during peak hours -- though the savings might not be worth the wear and tear.


Maybe I am missing something obvious for why this wouldnt be a good idea. Maybe Tesla won't do this because they dont want to replace batteries within the warranty period. Maybe they want to push powerwall sales -- but if you have a giant powerwall already sitting in your garage, running the house on it for a few hours a day seems like it could be worth it?

I found this post that might explain why this is a bad idea -- if true:


"You will burn through your CT battery cycles."

This is nonsense. Sure, it's equal to some extra miles on the battery, but...

...You'd have to use all of the power in the battery to be a cycle, and the average US home consumes about a quarter of the kWh in the battery across the entire day. The amount you'd use in peak hours is hardly half that.

Also, the battery ages every day whether you use it or not.

You may need a PowerShare Gateway along with a Gen3+ Wall Connector to enable full functionality.

Tip: There are still some PowerShare Gateways being resold on eBay by initial Foundation Series owners—so you might be able to grab one there if you’re looking to set it up sooner rather than later.
