I had a Fronius IG 3000 for 9 and a half years. It started giving me the state 104 code, it's on a 10-year warranty and they honored that and gave me a refurbished one. We still had the same problem, they gave me a new one, and the problem is still persisting. The only thing that's changed is around that time the LADWP installed a smart meter on my home. Has anyone else had problems like this? It keeps turning off and giving the state 104 code but the DWP says nothing is wrong on their end...

104 is not in my IG book, but that group seems to be related to power grid issues.
What error does your book define for 104, and have you checked out your AC
line conditions? One problem is voltage going too high, caused by a combination
of the line regulation and a high loss connection to the inverter. Bruce Roe
