I've been watching this thread and was uncertain whether to chime in, but
this affects multiple installers and businesses including other inverter
manufacturers, so I'm going to put my industry hat on and wade in, in
support of GTBB as a class.
This fight has been active since April - May, after t

I do a fair amount of work on ancient systems, just because there's
been off grid here for decades. I'm rewiring several old arrays for
my next door (meaning < 1/4 mile away) neighbor. The particular
array has six 53W Solec modules wired as three two-module 24V
Hi Mick,
I've got an 11-SQF-2 with dead electronics but happy pump end if you wanted to
do some swapping. GF instructed me to take a new unit out of inventory to
replace this under warranty & they didn't want the failed unit back.
BTW my company is an officially qualified reseller of the SQ
Hi William
I have been giving this some though.
As we know it makes no sense, now.
What don't we know about electric prices in the near future that might make
this
cost effective?

Ray and August:
Thanks for the speedy reply. I did confuse M250s with the M215s. The
actual inverters to be used are the M215s.
I swear I had a spec sheet for the M190 that showed 0.75 A but I can't find
it anymore. So using 0.8A:
9 * 0.8A = 7.2A
10 * .9A = 9.0A
Total = 16.2

William,
You have 9 M190s each running at 800 mA according to spec sheet. That
equals 7.2 A nominal output current. Plus you have 10 M250s (if you look at
your drawing) each running at 1 A = 10 A. 7.2 A + 10 A = 17.2 A * 1.25 =
21.5 A min breaker size. So, you'll need to round your breaker to a
HI William;
I think you might have a problem. Looking at Enphase's ratings, the
M190 has an output rating of 800mA, while the M250 has an output rating
of 1.0 A. 10 M250s = 10 amps, 9 M190s = 7.2 amps
17.2 amps exceeds 80% of your 20 amp breaker.
I know this won't actually happen, but my und

At the risk of asking a question that may have been asked and answered here
in the past, I wish to pose a question about Point of Connection.
Rather than outline the situation here I put it all on a web page. If any

Thanks for the prompt correction, and no harm done, except for to dash my
hopes! No to worry, I knew it was too good to be true. The concept of
running #8 ground with 20 or 30 amp circuits is now and always has always
been ludicrous. Oh well...

I would like to retract the part of my last post on this thread where I was
referring to the bare conductor size. My bad, I wasn't thinking clearly when
writing that last email. Lots of numbers in my head today. A #8 bare with #10
conductors is way out to lunch :/
The bare conductors are indeed
William,
With Tech90 regardless of the conductor size it always comes with a bare #8
included. A 3 conductor #10 (aka 10/3) will have red, white, and black #10
plus the bare#8.
A four conductor will have red, white, black and blue.

How is TEK 90 referenced in the NEC? Does it meet the qualifications to
be used inside an attic for instance?
Finally the onestopbuy link was very light on info; are the cables
inside stranded or solid?

William,
We get it with two pairs of color coded #8 copper and a #10 ground. Off
the shelf you can get #14, #12, #10, #8, and #6 and on up to 500 MCM.
The 14-10 go up to 10 conductors and the 8 and 6 go up to 4 conductors.
Here's a URL, not the cheapest place, but to give you an idea:

Hello, Wrenchies~
I supplied the Grundfos SQFlex 11 SQF-2 helical rotor pump to a client back
in the good old days before dear Grundfos decided us solar guys weren't
good enough to shepherd their pumps.
Serious drought caused the well to dry up; the pump got pulled but did not
get a rinse-through
