Subject: Questions for Enphase Reps [RE-wrenches]



Are there any representatives from Enphase on the list that can answer
questions about the new product?

I have so many questions about the product in general and how if
conforms to
Code in specific:

Is the DC system grounded?

Clearly there are DC source circuits, the Code requires disconnects on
these. It makes some sense based on the architecture that they can do
with
out them, but what about the Code which requires a disconnect on the DC
circuit?

The manual says:

"System Grounding
 Each Enphase Micro-Inverter has been provided with a ground clip that
can accommodate a 6-10 AWG conductor.
 Route a continuous Grounding Electrode Conductor through each of
the Micro-Inverters and AC branch circuit junction box to the NEC
approved AC grounding electrode."

This is somewhat misleading since the "DC system ground" must be a
minimum
#8 per Article 250.

Could be the best thing since sliced bread.......
