Midnite Solar has some DC arc fault equipment both built into their
charge controllers (for battery based systems) and their Combiner
boxes. The nice thing about having AFCI at the combiner is that it
actually protects the wiring from the array to the inverter, so if
an arc is occurring in say the attic, it will interrupt the
electricity at its source, not at the load.<br>

<br>
Does anyone have suggestions for the 'best' way to keep up with
product availability for meeting 690.11 on DC AFCI? I understand
that when this code section was written there was no available
device, and know that at least several companies are working on
devices. How will I know (before the AHJ knows :-) that
residential-scale products are available for purchase, and at what
point would you say now should be required over every other
option?<br>
<br>
Second question: I have an inspector insisting that the solar PV
system is the same as a utility service, and is requiring all of
the required service code references to apply. Anybody have a
concise reference that might convince him otherwise? This same
inspector has decided that the electrical permit will have adders
for each inverter as service equipment, and each module as an
electrical device. It would sure be nice if there was more
consistency...we're still in the early adopter phase here in
Minnesota.<br>
<br>
Thanks in advance for your input.<br clear="all">
