Con Edison.I'm also in NY and my system was also left on by installers, but they also told me if the utility co finds out the meter has been running backwards before PTO, they can technically fine me. I'm definitely generating excess power and selling into the grid.
May I ask which utility co you use and if they gave you trouble for running the meter backwards before PTO?
They installed the smart net meter months before installation even began.
My bill listed my net meter credits before PTO as well.
Unsure if they overlooked my case or just don’t care. But I took the shot. What was my other alternative? Call tesla and tell them to send a tech to turn off the system? I can barely get a hold of anyone anyway. Lol
