1: And of course some sort of isolation of the house from the grid when it's back-feeding.

Yep, and to clarify Pila includes an MID onboard so while Intentionally Islanded there is no backfeed. But in terms of a whole-home disconnect, I believe we'll see more generic options appear that are somewhat DER-agnostic.

>Pila includes an MID onboard

How does that work? Is just not putting energy out the input "plug" count as a MID?

The Tesla MID is in the Tesla Gateway or Backup Switch meter socket adapter. The Pila MID is onboard inside the battery. Pila can push power back through the plug.

When utility power drops, Pila & Powerwall react exactly the same. They both detect the outage, open the MID, and power load downstream of the MID. In the case of Pila it powers loads downstream / plugged into Pila.

Im having trouble understanding this, if you back feed into a circuit why wouldn't it go out via the beaker and onto the power grid?
