I've been trying to look into the UL3741 shutdown instead of doing module level shutdown, but so far, have not found any racking/inverter/shutdown device combinations that work -- primarily designing battery backup grid tie systems or off grid systems. My understanding is that all three need to be listed to work together, and I could not find any battery based inverters (other than Tesla and Growatt maybe) that were listed with anything else. Mostly I've just been doing ground mount arrays, or APsystems RSD devices on every module when it's roof mounted. But have not yet had luck finding equipment for a string level solution.
