Hello All,
We have several customers adding generators to their homes on which we have
previously installed PV systems.
Historically most generators didn't produce a clean enough 60Hz sinewave to get
the inverters to feed back.
However, with the generator technology improving and the introduc
HI all,
I’m doing a project with 2 radians in a redundant configuration.
Each one would go into a transfer switch to power the common load.
I’m looking for a good, fast transfer switch. 30amp 120/240 is fine.
And maybe a mechanical feature as well.
Code isn’t an issue

Hi gang. Contact me off list with any questions or concerns.
We've finally got our file attachment problem at least kinda sorta worked out.
When attaching files, consider the following:
1. The maximum message size (includes headers, message body, and attachments)
is 2 megabytes, and the smalle
In the past I determined that anything above a 4 pitch on standing seam roofs
would require rails. Just too difficult otherwise. I would recommend the use
of rails all the time however on larger systems, there can be significant added
cost. Because the seams don't align as a perfect multiple

Wrenches,
Just had a company reach out and ask if we could fix an Energy Innovations
Sunflower CPV system. Their contractor has gone out of business as well as

Hi gang. I'm still testing file attachments, please do not respond.
Sorry to bother you with these, but getting this figured out is important.

Ray - I agree with the others that S5 clamps with rails is the way to go on
standing seam roofs. We buy our S5 clamps through LMCurbs and I've found
their pricing and service to be good: http://www.lmcurbs.com/
We go though a good deal of effort to determine the exact standing seam
make/model and
Add my voice to the “never without rails” chorus.
1) S-5 clamps are only as good as the standing seam they are on. At least rails
spread out the stresses and avoid large point loads.
2) Ice likes to slide. Rails give some height above that.
3) Rail height gives better ventilation and hot wea
I would use rails with the s-5, gives you something to attach wires to.

Hi Ray
Here are a ton of newer clips that carry 2-many wires, in different
configurations, straight, 90 degree etc
Most in SS some now in synthetic.
And yea it’s kind of a pain with that type racking.
Talk to Bryan at PV cables, he stocks lots of them.

Wire management on railess systems is a challenge. In the past I have tried
to do as much of the wire management as possible before laying the panels
by zip tying the leads to the side of panels and strategizing string
routes. Also used flat trays like this for home runs:
