Keep in mind that a battery based system could sell to grid with no PV input. Yes, it would require reprogramming (which can be easily done on site) and ignoring the fact that your can’t do for very long or without some other charging source. Our local utilities have approximately an equal mix of battery-less and battery based systems so they pretty much take the stance that the disco must be on the AC side. They typically are unwavering about requiring the disco to be within feet of the meter which would negate the benefit of installing it on the DC side in my experience.

One of my previous colleagues negotiated this on a high profile project in a new jurisdiction. The inspector didn’t have a problem with this. You should definitely talk to the AHJ. It’s not a difficult case to make: no PV input = no inverter output.

On an add on system we found this had been done. It would be convenient to use this method.
