I have a 8.16 kW PV and 2 PW system that was installed Sep. 1st. Finally, got PTO today. My Gateway (small black box) said "No Signal" from the first day. My Tesla App was working fine as it was getting the info from the Gateway 2. I called Tech Support about the Gateway a couple of times, and they said it was not needed that I can put it away in the box. I had put a request in for the SolarEdge account a couple of weeks ago, but when I followed up was told that it will be submitted after PTO. I had been running extended test on the weekends of the whole system, so as soon as I got the PTO this morning, I turned everything on.
I called Tesla to get them to push the SolarEdge request through. They said that activations need to do it, as they had not got the PTO paperwork yet. Anyway, they did the activation. We also discussed the Gateway, and they said that it stopped reporting on the day I put it in the box. I asked them about the report that the Gateway is not passing on the info to SolarEdge, and he said that there was a firmware update for the Gateway, that was released recently, that fixes it. I was at work when I made this call. As soon as I got home, I reconnected the Gateway, and called activations. The person this time said that it is now reporting, and it would take up to 24 hours to properly complete (have heard that before). I asked her about the data to SolarEdge, and she also mentioned the new firmware. She said that she will run a diagnostic, and if the firmware is needed that she will send it on to that team. If what both said is accurate, then we may not need the ethernet cable. I will see when I get the SolarEdge access.
