We might have to agree to disagree.

We may

90.3 and 690.3 are only relevant if there is something in those articles that clearly contradicts some part of 230. Whether 690.14(A) contradicts anything in 230 is what we are debating, I think. My opinion is still that it does not apply to anything that is addressed in 230, because it does not apply to AC disconnects. Even if it did apply to AC disconnects, that would only mean that AC disconnects for PV systems would not be required to be service rated. It would not change any of the grouping or handle-limit requirements.

690.15 is a separate section from 690.14, and is therefore not relevant to the meaning of 690.14 in my opinion. Moreover that section applies to all PV systems whether connected to the grid or not, which is I think the main reason it is in there.

Well it definitely contradicts 230 being applicable. The question is whether 230 applies to the same disconnecting means required by 690 Part III. 690.1 scope says 690 covers in short the whole system and also mentions interactive systems. 690 Part III is titled "Disconnecting Means". That in itself is enough to say 690 and 230 conflict. 690.13 says dc conductors, while 690.14 does not... and 690.14(D) mentions the disconnecting means for inverter ac output conductors. 690(C)(3) and (4) covers the number of disconnecting means and grouping, and uses the term photo voltaic system.

I don't know why 690.15 is there either, but it supports that the disconnecing means includes the entire system, but especially a single disconnecting means for combined ac output.

There is no Exception No. 6 to 230.40. PV systems are covered by 230.40 Exception No. 5. I think you are confusing 230.40 with 230.82.

You are correct.
