I’m looking at getting two or three Powerwalls. I have an existing solar installation, so just trying to understand the pieces and interconnections.
It looks like Tesla’s standard approach is to split out the “essential” circuits from lower priority circuits.
One of the scenarios, I’m trying to understand, is during normal operation, with the grid available, and during peak power period. I wouldn’t want to use grid power during this period, when there is enough power in the batteries. I know the circuits in the “essential” panel would be powered from the Powerwalls, but would the lower priority circuits be powered from the Powerwalls as well? Ideally, I would want them to be powered from batteries, and shed if grid power was lost.
What would be the downside if we chose not to separate out essential circuits, and had the entire home treated as essential. If we did this, and lost grid power, does the Powerwall system “trip” if the load exceeds the Powerwalls max output capacity? Or, does the Powerwall fail to deliver in a more unfriendly way - i.e., with low voltage.
Does the Powerwall system provide alerts (text), when grid goes down, and PowerWall is sourcing the power? I could see the possibility we wouldn’t know power is out, and we are pulling from the PowerWalls. And, happily using appliances we’d otherwise shut down
