My electrician has a customer who wants to replace their old Fronius inverter with a new hybrid inverter and add backup power. This is straight forward, except the system was installed ten years ago, before rapid shutdown was required.
Since this isn't common (yet) I haven't found any information on whether we'll be required to add rapid shutdown or not. If so, it's a much more involved project.
I'm calling the AHJ (Arvada, CO) and will submit a request to Xcel for more information, but Xcel can take months to respond to a request. I'm hoping someone here has an instinct, if not a definitive answer.
And yes, I recognize that ultimately the AHJ and Xcel will decide, but if they hadn't considered it, I'd like to be armed with information.
Thanks!
