On large arrays with combiners and sub combiners, will a disconnect be
required on both the inverter and array side? The fuses will still
be energized from the inverter side when the array is turned off, from
other string sets connected to the inverter. . <br><br>

Disconnects within sight of combiner boxes will be required in 2011.
Another good reason to keep combiner boxes off residential rooftops. This
is targeting commercial rooftops where large system have no disconnects
for servicing fuses.<br><br>

On that note Bill, will roof disconnects be required in the 2011
NEC?<br>

It does not exist. We tried like crazy to get it into the 2011 NEC, but
to no avail. At the last second the proposal was put on hold until the
2014 NEC. Major bummer. For now it can only be done with AHJ approval.
Many allow it but it is not in the NEC. Alternatively you must use the
sum of supply breakers no greater than 120%. Much more restrictive.<br>
