The 2 Lithium batteries I use are HALT tested but it is always a big risk
with a battery that may out live many of the clients. The math on these
batteries has them lasting 30 to 40 years offgrid and that is pretty hard
to believe! Will the BMS fail or the battery?
If they can afford it I have

How about an insulated loop clamp like this one:

You can get them in stainless and they have the rubber grommet so it won't
touch the rack.

Good Morning Wrenches,
I am required to keep the bare #6 copper from touching the aluminum frame
work of a Array Technologies tracker where it is not mechanically connected
by a pass-through ground clamp on a tracking array [dissimilar metals] and
am looking for a lead on an insulated standoff
Why is it #6? Usually the solar panels wire size determine Array Teks size
for this wiring. What do they say please? --Dave

Hi Ray,
The stand-alone diagram calls out the PV system disconnect right after the
PV system DC circuits and prior to the point of common coupling with the
batteries and the stand-alone inverter. Yes, you are correct a controller
or DC to DC converter is not shown in the this diagram or the
Greetings Dana,
You may consider sheathing the bare copper wire in a product
appropriately rated for the outdoors and UV etc... Possibly
Liquidtight Flexible Nonmetallic Conduit (LFNC), electronics
insulating sheathing, continuous grommet channel, heat shrink tubing,
or some type of weather
You should not have to run a EGC/GEC along the with Array Technologies. When I
have installed these in the past we always mechanically bond within the
bicinity of the conduit or box we are running our wiring through. No need to
non-mechanically attach anywhere.

That was my question as well. USE -2 with green insulation is
available. Sorry to hear about AHJ's in Idaho being stuck over a decade
back. I thought that array grounding was UL listed and better spelled
out now in NEC 2017. What code cycle are you all on?

According to our state plans examiner; all modules, module rails shall be
bonded. The array Tech tracker is not on their approved list of self-grounding
racks. It is a 3-4 product list. Initially I was told I was going to have to
remove the trackers. Since then they have mellowed a bit.

Dana,
Why does it have to be bare copper? Can you not use a green insulated #6?

Dana, sometimes I virtual track if I think that city hall is going to be a
problem. Virtual tracking also has better wind/snow loads on Mountains and
easier with the crazy requirements in hurricane zones.

"we go where powerlines don't"
Or just thhn #6 ?
