GoodWe inverter problems

I don't have any data, but round here (upstate). NY the closest the POCO comes to looking at a resi solar system is the guy who installs the net meter. You could have a bunch hamsters spinning a wheel with a generator on it and they will never know.

For a rooftop inspection on a school one time, the inspector looked at the bank of 30 SMA SB inverters and remarked, "So these are microinverters." The PM and I just looked at each other and shrugged.

That's about as bad as one of my concrete pours when I told the driver I wanted the slump at about 6 and he said "what is slump"?

Actually I was only even talking about SA, which is automonous dynamic response with no utility control. As far as data, I mean, I've not seen any from the utilities or state but as far as the systems my employeers have installed (all resi in that time period, with PG&E) I've seen zero spot checking of enforcement of either set of requirements. It's basically honor system with a bit of a check through the AHJ permit approval that you installed a capable inverter. That the SA or SB functions are actually enabled is totally honor system on resi systems AFAIK. As I said I would be surprised if they weren't checking this stuff on megawatt systems, but I don't work on those. Maybe the other major IOUs are doing something that PG&E isn't (I certainly wouldn't expect the vice versa on that).

Yeah, SA in-band smart inverter compliance would be harder to check functionally since POCO's would need to actually change grid attributes (e.g. frequency). It should be easier to check SB compliance since it's addressable to individual systems if the POCO's have the out-of-band command/control systems in place. At this point I doubt the POCO's even have the systems in place at least for resi systems. Just seem like a waste and blocking solid gears like SMA getting installed.

Yeah. I suppose there is a case to be made about having inverters capable of this in place for if/when the POCO needs that functionality. NYS seemed to be a very early adopter of the supplement B, which is kinda interesting as NY generally lags pretty far behind on codes and standards. I would be curious about the reasoning.
