By the way, the pedestals are NOT labeled 'A' and 'B' as one typically sees at V2 sites.
Are the pedestals labelled at all right now? The numbers and letters are usually done once Tesla tests the site.

These are the PowerPack batteries and the Inverter for the PowerPacks. Max input/output is 350kW. There are 4 PowerPacks, so that makes 720kWh of energy. That means that this is a "2 hour" system. Basically, it is for peak shaving to reduce utility demand charges. When the site gets busy, it will discharge the batteries to reduce the max kW that the site draws during any given month. A significant part of the utility bill is $/kW peak during the month. The energy charge in $/kWh is relatively low.OK, so I visited again - Sunday, nobody around and gate still wide open. I unzipped a couple of bags and checked all sides of the 5 bagged cabinets - nothing. I found the following on the 4 battery pack cabinets:
And then I found the following on the single large cabinet with the "TESLA" logo on the top:
I don't see any combination of volts and amps that would get me to 250 kWs. But I really have no idea what I'm looking at. Someday after this site has been completed, somebody can post a picture of their screen while charging and we will know.

I am not too much of an expert either but I am wondering about the three phases high voltage power lines going to a transformer.I am no expert when it comes to electricity, but 350A times 500V is 175,000W and I thought V3 was 250,000W.
Can somebody explain this to me?
The electrical service used by Superchargers is 480V 3-phase in a Wye "Y" configuration. This means that there are 3 phase wires, a Neutral wire, and a ground. The 3 phase wires, L1, L2, L3, have 480VAC between each other and 277VAC to the Neutral wire. The Neutral is grounded at one location. This service is provided by a utility transformer which is usually reducing the voltage from "Medium Distribution Voltage" like 22kV.I am not too much of an expert either but I am wondering about the three phases high voltage power lines going to a transformer.
- Does the transformer used by a Supercharger have also three output lines?
If so, does the above mention of "350 A" and "500 V" should be for each phase?
Then the combined power would 3 times (or may be 'root power' of 3, because of the phase ?)
So I could be 175,000 x 3 = 525 kW
(or 175,000 x (3^) = 303 kW)
Note: Sorry about this candide question if I'm wrong.
Today, Saturday 8/31/19 I stopped by. Construction fence is gone but they are not labeled or operational yet.
There are no numbers or letters currently on any of the 20 pedestals. That, of course, could change after testing - we shall see.
This article is about other EV charging, but the Santa Rosa Supercharger gets a couple of mentions:
20 new Tesla chargers among hundreds of new stations coming to Sonoma, Mendocino counties
Bruce.
When a SC gets to the "now it's up to PG&E" state, it could be a while. Be patient.Any new info on this supercharger.
Why does it not take long for them to increase your bill.When a SC gets to the "now it's up to PG&E" state, it could be a while. Be patient.
Three weeks to get on the EV-1 plan, though. Foot dragging when economically expedient. End Rant.Why does it not take long for them to increase your bill.
