But I thought SS and GroWatt made special deal that the units (5000 ES for Euro) sold to SS is modified Euro unit, but if GroWatt already makes 5000 US model that are sold to general public why would SS bother to bring in modified ES model, just sell 5000 US then, it is confusing to me.
Do you have instrument to perform Hi-Pot test?
I think that's why there isn't any lawsuits yet, but as you've said yourself, you're not an EE guy. You're sales and marketing. It would go a VERY long way for Growatt and Signature Solar to get a session together scheduled with your findings and to answer questions of experts that are here. Hell, I've literally designed and had power modules UL certified and there's still people in here that know more than me, but I'm still more knowledgeable than anyone that either company has put forward at this point, which is the problem.
What Will Prowse Video? He made a thread and made a link to Ian's video on the problem.
First off with 5k of these being sold in the U.S this issue has not shown itself. You certainly have no proof That Signature Solar or Growatt did anything malicious. I have just spoken to growatt and they just heard of this problem today, they are now looking into it. The fact that growatt just introduced there own Transformer leads me to believe this has not been a problem. The gentleman is tired of the abuse he has received on this sight and all you did was add to it
The video he posted today on YouTube describing this issue with the Growatt 5000ES. It's gone.
Really I had no idea he posted a video today. I wonder what happened, maybe SS got him to take it down.
Did you contact growatt? I did and they just heard of this issue today and are looking into it. No one is obligated to respond on a forum with wild accusations of possibilities being made. What experts are you referring to? No one here has even tested the unit for these problem and no expert would speak to an issue without first confirmation
Read that carefully and tell me that that claim holds water. They literally have developed a transformer, are marketing it and selling it today, that solves a problem that they just heard about today.... ?
Scroll back through the tread. There are both electrical engineers and certified electricians that have for several months now being telling the world that there is a problem. And there are videos from 3 months ago showing the problem and outlining work arounds and how it doesn't solve the full issue on YouTube. A casual search will find them for you and I'm absolutely sure that this has even been brought up for months in the comments on Poz's video. This isn't new and there is no way for Growatt to have manufactured a transformer that solves a problem before they heard about said problem.
You have made a leap when there was no trench. Rather then allow a 3rd party to supply the part they started producing there own. Signature Solar lost money on every solar edge they sold. UL is not a legal requirement in the U.S for Sola, local zoning laws and electric companies may require it to feed the grid. Maybe you should trying to talk to people instead of looking for a away to make points.
And I am suppose to believe you vs the #1 seller of inverters in the world A industrial master electrician and a master electrician with no reason to lie?
His video was linked to in Post #195 also. It was video describing in detail the safety concerns with the Growatt 5000ES model inverter and split phase transformer. Same thing this thread is discussing. He gave his opinion of why he wouldn't use it, doesn't recommend it. I'm anxious to hear why he took it down.
And I am suppose to believe the #1 seller of inverters in the world A industrial master electrician and a master electrician needed to be told this is a problem by people in "armchairs"?

Yes, just took it down a little while ago. I just talked to signature solar and there is a huge issue I noticed in the growatt marketing material. Signature solar unit is the 5000US, not the ES. Growatt did not update the manual, and signature solar called it "ES" on their product listing. Huge issue here.
