690.9(D) is not applicable to the original discussion because we were talking about an Inverter output circuit, not a PV Source or Output circuit..
690.34 may apply if you call a SolaDeck with breakers a junction box, but I can see that being a stretch in the mind of many. My and Ray's question about the screws on the SolaDeck cover itself requiring a tool to render it accessible is still an issue if the breakers themselves need to be "readily accessible," but that would also apply to a Midnite MNPV, which also has a cover with a screw.
