Hello, Blake Gleason & All the Mechanix~

Hi, Mechanix~
Kirk Herander asked about cable trays & basing the wire calculations as if
the wires are in "free air". The 2023 Article 100 definition of Free Air is
unchanged from the 2020 NEC:

air flow around an installed
Hi, Wrenchies~
Drake Chamberlain asked about renting a gadget to locate the point where an
underground wire is broken.

Hi, Mechanix~ I have several local clients with various different versions
of Magnum pure sine inverters & all of the inverters seem to transition to
the float stage soon after the charge cycle begins. I've observed this even
when the inverters & batteries were brand new. I'm aware of the menus abo
Hi, Mechanix~ Web portals such as Optics-RE make for easy well-baby visits
for off gridders. The prospective customers that I met yesterday aren't
here full time so they may not want to commit $1200/year on satellite
internet service, but the Verizon 4G signal is strong at the homesite.
Which web-
Hi, Mechanix~ Is the Mate3S in short supply for mid to late 2023? I see
there's a "Lite" version with no internet capability--but are enough
projects buying the Lite so those who want the full version can still
get it from inventory?
Thanks in advance; the Wrench List is the Bomb!

Hi, Mechanix~ My off grid project needs dual 40kW diesel generators with
easy manual selection between "A" or "B". The output from the manual switch
would feed AC into a set of XW Pro inverter/chargers.
I seek a 200a manual xfer switch that can also changeover the 12v+
generator automation wire wi
Hi, Mechanix~ I asked a Greentech location about quantity four Fronius
string inverter PRIMO 6.0-1. (6kW AC output, single phase 240 volt 60 hz)
This p/n is in the Greentech portal but my particular branch hasn't done
much with Fronius. Today the branch manager told me "Fronius no longer
exists."
Hi, Team and >>gosh<< I must apologize to connell.christop...@fronius.com and
to Fronius.
I'm sorry that I inadvertently fueled an untrue rumor about Fronius USA.
Chris, I should have tracked you down for the correct answer before putting
my question on the List. I will also correct this with my Gr
Hi, Mechanics~ Any experiences with the pump in my subject line? It's
variable speed (constant pressure) in a similar category as Grundfos
Scala2. I see the Scala2 has garnered some bad reviews for leakage
problems, etc.
The Esybox Mini seems to mostly have 5 stars. I'd be using it with an

Hi, Dave Angelini & All~
Dave posted his usual thoughtful remarks, reminding us that "Murphy" of the
infamous law is...everywhere... My reply is below his remarks, thanks.
"No experience but I am interested. I see your pump but it has not been out
there long. I can't find it a Home Depot which I

Hi, Mechanix~
My off grid project gig has redundant 120y208 generators that need a 200a
"break before make" manual transfer switch so the clients can choose
machine A or machine B. The switch has a lockable center-off but I think
the generators aren't set up for "lock out tag out". The machines &

Hi, Wrench List colleagues~ I have a minor dispute with a technician at one
of the solar superstores. He says the amp rating on SolarEdge optimizers
needs a 25% "safety factor".
SolarEdge's spec sheet says "Maximum Output Current" for model S500 is 15
amps. I'm not sure if the technician would tak

For PV to "AC couple" with the storage, it's correct for the SolarEdge AC
