Not sure about this one.
He is stating as fact that the PW+ is a DC coupled battery now instead of AC, but the spec sheets for it still refer to 90% 'round trip' efficiency which would mean AC coupled.. ?

Update, I got my much-more-experienced project manager on the phone. (he said the previous guy started last week).Interesting, I chatted with rep this morning about install starting next week. Its a 6.55 kw solar roof with 3 PW's. This rep seemed moderately knowledgeable so who knows if everything he said is accurate. He said I'm getting the latest equipment (obviously he's going to say that in this context!), 'Powerwall 2'. When I said the previous one was called 'PW 2', he said 'no' that was just called PW and the new one is called 'PW2'. When I mentioned '+', he said that's called 'PW2' now. Clear as mud, right?
As far as capability improvements, he didn't mention increased power output, but said the new integrated set up enables much more seamless transition from grid to off grid. This makes sense based on what I understand of the new set up and does seem to address the issue I've heard about of less than seamless outages (ie resetting clocks, etc). Does this make sense to others?
He says Powerwall + and GW2. Confused. The Powerwall + I thought needed no separate gateway?We've got a forum member who has a Powerwall+ as part of their layout proposal: Post Your Tesla Solar Layout
Please keep us updated on how your install goes, @mec37 ! We haven't seen a Powerwall+ installation in the wild yet.

I do not see on drawing either, but he states it in his comments?I don't see a Gateway on the system schematic. But I do see "Product 1: Powerwall+ Tesla, Inc. [240v] #1850000-00-B 7.6 kW / 13.5 kWh."
Also is the meter socket in the diagram a known component? That says it's rated for 125 Amp.
Looks like Elon wasnt being accurate when he said panels will only be sold with powerwalls last week
What a crazy way to run a huge company.
On another thread I speculated that they just gave the inverter more surge capacity and the marketing guys called it soft start "capability". They could have used the Maxwell technology to add that surge capacity to mimic soft start. I am not an EE either but as far as I know it is the same power but just spread out over a little longer start up time. I view it as similar to what a pre charge resistor does when an inverter with big caps first connects to a battery.Anyone else wonder if Tesla could have built the soft start on the Powerwall+ side with the Maxwell ultra capacitor? .............Clearly Tesla can’t physically slow down another device’s motor torque from the powerwall side.
I was reading on the TeslaSolar subreddit and someone said they had their system installed on the 19th and they confirmed it was the Powerwall +...this can't be right, my understanding it isn't released yet, right?He said my install is getting PW2 and said the + model isn’t really available yet.

I think they're confusing PW+ with PW2.1. If they got PW+ (combination inverter/PW), they wouldn't need to confirm anything. It's evident from the shape that it's got the inverter on top.
So they probably mean PW2.1, which is the version of Powerwall with higher output.
No, we have no verified data that any PW2 or 2.1 will get FW to get it out surge output. We have no verified data of the difference, if any between pw2 and pw2.1I think they're confusing PW+ with PW2.1. If they got PW+ (combination inverter/PW), they wouldn't need to confirm anything. It's evident from the shape that it's got the inverter on top.

That is at least logical. It is not what I was told about my units, but I guess time will tell.Here is a video with an alleged way to tell if you have the Powerwalls with the potential for higher output.
I’ve been a lurker for a while. Not sure how to delete my previous post. This one to the video is much more direct…
