Will the Powerwall4 be the Powerwall+++?The owners manual listed on the FCC site lists the Powerwall 3 as the Powerwall ++.
9540A is a data providing test, not a certification. Given the low propensity for thermal runaway in LFP cells, it may not be that useful.I'm a bit disappointed that it doesn't appear to have passed UL9540A.
Also, the label said that it is made in the USA. That means that it probably doesn't have LFP batteries. LFP batteries are currently only made in China. For something to be labeled "Made in the USA," virtually all of the significant parts must be of U.S. origin.
The owners manual listed on the FCC site lists the Powerwall 3 as the Powerwall ++. There isn't a lot of into in the manual, but it appears that the Tesla logo may light up.
How does this work if you order Powerwall direct? Can the order be canceled before a purchase agreement is signed?Negative. Your $100 deposit is entirely refundable until installation is scheduled.
Not sure. Just read the terms before you submit the order.How does this work if you order Powerwall direct? Can the order be canceled before a purchase agreement is signed?

What You Need To Know About UL 9540
UL 9540 is a Listing that produces a listing mark. It is a pass/fail criteria, and therefore easy to say yes or no this is listed.I'm a bit disappointed that it doesn't appear to have passed UL9540A.

PW3 is assembled and made in USA at Gigafactory Nevada. Just because you don’t understand what made in USA means doesn’t mean it’s not.
No, I think that would be “Assembled in USA”. Imported raw materials/parts + final assembly in the USA.Exactly, all the battery cells are foreign but if they are put in a box with some stickers in the USA then it's "Made in USA". Same game Chinese vendors play to get around the tariffs by doing final assembly in Vietnam with "Made in Vietnam" stickers. The whole "Buy American" thing has been made a farce.
It all depends on the interpretation "almost all or virtually all raw materials". The US government is only starting to try to go after some Chinese vendors playing the "Made in Vietnam" game years later. In the meantime, the Chinese vendors and their complicit America corporate customers have made lots money with little or no penalty.“Made in the USA” would have to be almost all or virtually all raw materials are sourced from the USA and final assembly also occurs in the USA.
I think they were lazy. My house is grounded to cold water line and one ground rod, built in 2002. Now they require UFER ground, so perhaps the electrician took a measurement and determined it wasn’t necessary.This may not be the right thread to ask, but... Can anyone explain why Tesla is insistent on grounding the system to the home's main water supply pipe? I noticed on the first pictures I posted of the Powerwall sitting on the driveway right after it was shipped and the shipping label says a pair of grounding rods were included. Why can't they just pound these into the ground right next to the system rather than run 50+ feet of ground wire + conduit over to the water main?
Oh they most definitely can, but be careful what you wish for, lest you end up with ish like this.Why can't they just pound these into the ground right next to the system rather than run 50+ feet of ground wire + conduit over to the water main?

I'm not an expert, but I believe that updates to building codes require two grounds unless it is shown that one has a resistance of less than 25(!) ohms, and also that the cold water line be bonded to the ground at the entrance to the home. I think that might explain your observation.This may not be the right thread to ask, but... Can anyone explain why Tesla is insistent on grounding the system to the home's main water supply pipe?

Because the NEC requires it. Any metal water pipe buried in the ground for 10' or more is a grounding electrode. All electrodes present have to be bonded together to become the premises grounding electrode system.This may not be the right thread to ask, but...

Is the inverter that lots of people have a problem with the one that is part of the Powerwall+ or is it the other inverter in the system. I'm wondering if the Powerwall 3 will help slow down the inverter replacements any.
