We dropped the gird using the HBX like Phil mentioned and allowed the wind to
charge. It took 4 hours for the loads to drain the batteries to LVC. I
thought the charger would wait an hour and then search for grid to charge, but
it never did. Either way, it got the point across to the homeowne
I've seen a video a solar installer friend of mine made of a similar unsuited
disconnect trying to break a high VDC string of modules. The disconnect opened
and the arc was able to jump the gap and start the insulation of the conductor
on fire.
Has anyone seen/heard of the square D not exting
The problem with this stuff is not passing inspection, it's actually turning
the system off under load! I think if you watched the arcing on the contacts,
you would agree that the system you saw has only a very limited number of
switch cycles before it fails.. possibly in the ON position.
I've been using similar "solar" disconnects. Its nice to see UL. I looked
at a local solar project today that the installer used GE 600VAC/250VDC
disconnects on the DC side. Three strings with each being broken by one
pole. It had passed inspection.

We switched (ha!) to Siemens disconnects after the hoopla about Square D..

I'm using it pretty often, all my proposals are modeled in Sketchup using
Skelion to attach the modules. It helps me determine the best layout and
produce a power rating.
I don't have anything to trade though.

Hey gang,
If anyone out there is using Sketchup to do solar related layouts,
drawings, or engineering, I have a pretty sizable component library that I
am willing to share/trade. I have not uploaded them to the 3D Warehouse,
and now it would be a bit cumbersome to go back and attach descriptions t
Sounds like a case of bad design, misrepresentation to the customer
and not understanding the equipment.
If they have FX3048T inverters, they cannot sell excess RE generation

assumptions about the installation of these particular turbine
But you can use one e-Guage to look at 6 different current flows. The
e-guage has 12 CT inputs, and shows all the data online.
