I think 240.24(A)(4) allows the installation of the inverter OCPDs
in the SolaDeck hidden under a module.<br>

<title>National Electrical Code 2008 Edition</title>
<b>(A) Accessibility.</b> Overcurrent devices shall be readily
accessible and shall be installed so that the center of the grip of
the operating handle of the switch or circuit breaker,
<title>National Electrical Code 2008 Edition</title>
when in its highest position, is not more than 2.0 m (6 ft 7 in.)
above the floor or working platform, unless one of the following
applies:<br>
...<br>
(4) For overcurrent devices adjacent to utilization equipment that
they supply, access shall be permitted to be by portable means.<br>
<br>
<br>
And if panelboards / fused safety switches are allowed to have
screwed-down covers over the OCPDs, I'd think that installing a
removable module over these OCPDs would meet NEC. I guess an AHJ
could argue that this requires TWO covers be removed, unlike a
panelboard or a switch.<br>

If that is the interpretation,<br>
I don't see how the breakers are
"readily accessible" in a SolaDeck<br>
mounted anywhere, regardless of
whether it is under a module. It<br>
requires removal of four screws (using
a tool) to access the breakers<br>
inside the enclosure. It's all up to
the AHJ. It has not been an issue<br>
locally here. I can see how other
jurisdictions may not<br>
concur. </p>
