[RE-wrenches] Solar accumulation panel

[Carl Adams]

Andrew,

I have done this for multiple installs, most recently on a commercial
three phase 240 install (with 6 SMA 7000s) and a residential two
circuit Enphase install.  The plans were submitted to the AHJ and
approved in both cases without question.  I labeled these per 705.10
and 690.64.

The commercial install was as you suggest to simplify the grid
connection.  The residential Enphase install was done to provide a
single point of metering for the system.

I hope this helps
