Re: [RE-wrenches] Curved solar mounting

Have you looked at the Lumos system?  They are not cheap, but look nice,
and would work well in this application.  The rail has integrated wire
management.

Re: [RE-wrenches] Curved solar mounting

2019-02-08 Thread August Goers 
Some more ideas:

If you want to go custom, you should be able to through-bolt to the bottom
of the module frame with standard stainless hardware per the manufacturer
instructions. Here is an example from SunPower's installation guide

:

"Frame Holes: Secure the module to the structure using the factory mounting
holes. Four 1/4″ stainless steel bolts, with nuts, washers, and lock
washers are recommended per module; tightened to a min. torque of 10 inlbs.
Refer to Table 4 for the module dimensions and hole locations. This method
has been certified by a third-party organization according to UL 1703. For
frame hole mounting, modules must be secured using the holes located at
322mm from the short end of the module for 72 and 96 cell modules and 433mm
from the end of the module for 128 cell modules. For carport installations
the supporting structure has been pre-drilled. For 128 cell modules for
carport assembly, modules must be secured using only the holes located
433mm from the ends of the module and hardware described above in Section
4.1, Item 5. See Figure 2 for carport assembly details."

We typically spec out an EPDM pad or washer between the module, rail, and
or sub rack system to avoid dissimilar metal corrosion unless the materials
are all the same.

For wire management, there are more and more clips available on the market
designed to secure wiring without needing classic zip ties. Maybe your AC
module manufacturer has accessories? When cable ties are needed, I always
like using the Heyco Sunbundler

.

Just some thoughts,

August

Re: [RE-wrenches] module level control for offgrid

2019-02-08 Thread Lones Tuss 
Hello Jay
Well it seems that I can't leave well enough alone. 

Below are some links I have found to the Tigo and IMO products concerning 
module level shutdown.
Both have been tested with OutBack products.
I do not think Tigo or IMO have a presence on Wrenches and I know this is 
gaining importance. 
I hope this helps.
 Take Care All 

Tigo 
https://www.tigoenergy.com/about-tigo/certifications/rapid-shutdown-system-modules/


IMO Fireraptor is a module level shutdown system that is tested and works with 
OutBack gear.

HI All,

Well its the new year and Module level control is here. 690.12 (B)(2)

Does anyone have any updates as to products that work with CC's that meet it?

Thx

Re: [RE-wrenches] Curved solar mounting

2019-02-08 Thread Jason Szumlanski 
I don't think I'm going to get the spans I need in this high wind area with
an off-the-shelf aluminum solar rail. I think the purlins will need to be
steel. I'm thinking either Z-purlins or I-beams. I have to mount the
modules in landscape. I guess what I'm really looking for is standard
hardware that I can bolt to the purlins/beams and bolt or clip to the
module frame.

These will likely be AC modules, so I also need to consider wire management.
