SS is by far the worst at this. I had the same issues. Incorrect documentation. Dangerous. Support team that tells you 3 different answers depending on who you talk to. I returned my EG4 3000 EHV last year when I could not understand why things were happening. It was so frustrating because SS not only couldn't help, they tell you wrong and dangerous information.
I'm getting delivery of the same inverter because I thought they fixed the issues and put out new videos. But, the same issues still exist. No documentation describing how it works, they tell you that you can't remove the NG bond screw or it voids the warranty. So you can't set it up to power your home when the grid is down.
An off grid inverter that you can't connect to your home when your home is off grid. It's insane!
