Strange outage #255

Closed apographon closed 4 months ago

This is not a HA Integration issue - but I'd like to hear your voice.

This morning at 07:05 my house went offline! Complete outage. By accident I checked the Battery before and I was down at 5%. The Sungrow Logs shows error 51 for this moment (Netzunabhängig Last P-Über Fehler) At 07:08 the Sungrow Logs indicates a Grid Error 10 (Netzunterbrechung) and a Battery Error 703. This two errors could be indicated by me as I turned the PV master switch OFF. I tried to isolate the Error and switched all fuses off to "restart" the house step by step. As the Smart Meter was on Power but my house been offline, is was not a Grid Outage. I tried several restarts, suddenly without further interaction (I was calling the Grid operator to exclude Grid problems) the Power was back.

Most funny thing: After everything was back, the SoC was 22% (!!!). The SoC was at 5% at the morning! I have Home Assistant Data to proof this!

Does anyone has an idea?

Appreciate any Feedback/Comments.

Thx!
