The Solaredge "Key" and "Safety & Monitoring Interface" have cut sheets

Our experience with REC is similar to previous respondents. We almost
solely installed REC modules for the better part of a few years and have
over 12,000 (4.31 mW) of them in the field. Ironically enough our first
warranty claim for one was a couple weeks ago (failed diode). The

If we take a deep dive into this issue we may be able to close the loop on
whether the industry is in lock step to leverage its synergy and make the
necessary paradigm shift to pivot. Alternatively if there aren't the

Adding in my vote for MT Solar. Quality product, quality customer service.
I saw someone mention Wattsun as well but their product is trackers not
simply pole mounts. They too have superb customer service but not for
static racking.

Dear Wrenches,
I'm trying to determine whether or not it is acceptable to clamp monitoring
CTs around hot conductors. For this question please assume the CT wires
are landed in their proper terminals and that proper PPE/safety protocol is
employed. The monitored currents in question are

We have two Sol-Ark / Fortress deployments just finished/in progress and
one uses seven Lumin panels for load shedding and the other has SPANs. In
retrospect the Lumin project should have used SPAN since it was a new
construction project and the Lumin is more of a retrofit product in my
opinion.
Here is an official communication from Fortress that we received recently
when inquiring about monitoring Fortress batteries as an Installer. Some
of you may find the info relevant.

James,
I can think of one install I performed in 2017 that was a metal roof over
metal purlins and we opted to through-bolt the entire array using one
installer on a ladder inside and another on the roof. We employed butyl
mastic and large fender washers to attach a strut frame to the roof, and

I have a dusty stack of SolarPro magazines and am curious if there are
folks on the list who might want them. At a glance I see issues from 2014

some copies of Home Power in there. Please contact me off list if

Can confirm. We receive email from customers on the regular that these are

Good Morning, Dave,
Take a look at this pdf and see if the info about setting up "Grid
Protection" gets you anywhere. Starting on page three it shows how to make
the Vmin/max and Fmin/max for screened inverters. What I can't verify for
you is whether the A series has the same menu structure as

I visited this site this morning and found AC and DC voltages at the
inverter terminals to be within expected range (432 Vdc and 246 Vac).
Since the error code on the inverter specified it being an AC problem I
removed the upper cover of the inverter and traced all the terminal and
soldered
Barton, Jerry, Ron, and Drake,
Thanks for adding your initial insight into this situation. It provided me
a few perspectives I hadn't considered right off the bat. There were also
questions that some of you posed that I don't have the answers to yet as I
haven't visited the site nor spoken with
Howdy Wrenches,
Any "old timers" here care to chime in with some basic info on what I might
be heading out to see at a 10+ year old ground mount? It's a Xantrex
displaying the message AC Fault 186.6v. I'm prepared to head out there and
troubleshoot blind if no one has anything to offer up but
*> Was surprised by one manufacturer who advised us to read that bypass
diodes were not an warranty defect *

Forgive me if I'm daft but someone please tell me WHAT IS a module defect
if a failed diode ISN'T?!?
Unacceptable.

If your company installs SMA Core1 inverters you'll find these ferrite

other miscellaneous

In order to step up our commissioning and testing game and to take
proactive steps to spot isolation faults and test insulation resistance
prior to our systems getting PTO it is time to invest in a Megger. I am
