[RE-wrenches] grounding the Enphase inverter

[Dana]

I would like to remember us all back to 16-20 years ago when
we were required to use a ground cable "equal" to the
largest conductor in the system. This was typically sized by
the inverter cable at 4/0 copper. I gotta say that was a
really dumb rule. 
At that time we were to "not create " ground loops. One
point of ground was the maximum for the DC circuit. 

Today's grounding requirements create ground loops [ in my
opinion]. I wonder where this topic will ground out, 10
years  from now. I am delighted to be done with 4/0 ground
cable though.
