Show HN: We built a Plug-in Home Battery for the 99.7% of us without Powerwalls

Yeah great question. The hardware is capable of bidirectional power, and electrical codes and standards in the U.S. are now catching up with Europe. “Balcony Solar” has taken off there, especially in Germany. Utah just passed H.B. 340 which allows up to 1200W of plug-in solar backfeed. It wasn’t so long ago that grid-tied batteries like Powerwall were working through the same kind of standards updating process to participate on the grid, so I’m encouraged

Interesting. How is this being managed on the device level? do devices ship with this functionality and configure it based on their state code?

Yep! All hardware is capable, and the Grid Code configuration can be set and updated at any time. So as more states follow suit, Pila's ready

Are the grid isolation and backfeed capabilities mutually exclusive? Isolation would have to happen at the panel if you are backfeeding into an outlet, right?

So this is supported in the EU?

Yes & in Utah.
