Re: [RE-wrenches] Voltage Degradation with Uni-Solar laminate

Some interesting results: ie. High altitude BIPV suffers reduced degradation because of minimal snow loading. (I assume because of less flexing of the substrate?) Array degradation was often listed as twice the module degradation. Offering a challenge to make the installation better? I left

[RE-wrenches] Integrating with Lightning Protection

Wrenches, Does anyone have any best practice recommendations (or books, articles, etc) for integrating a roof mounted PV system with a lightning protection system? Bare #6 copper and a split bolt to the braided copper connecting air terminals? At both ends of the array? Or should we not bo

[RE-wrenches] #2 -#8 AWG Crimpers

Greetings wrenches. we would like to vet a good quality crimper for crimping copper ring terminals to our mid range wire sizesAny of you have a good quality crimping tool you can recommend. ...wire sizes I am looking to crimp are #2-#8 AWG. Thanks in advance! Kirpal Khalsa Oregon Solarw

Re: [RE-wrenches] Integrating with Lightning Protection

I think an important point, is not to connect to their system in more than one place. You don't want to create any loops that would pick up the induced current from a lightning strike. We've bonded to the lightning rod systems at their attachment to ground. The idea being that if their syste

Re: [RE-wrenches] Integrating with Lightning Protection

DEHN has some great resources for various types of PV systems, and a chapter on it in their free lightning protection guide. Haven't looked in a while but seemed like great info. Brian > On Jun 4, 2015, at 1:03 PM, Garrison Riegel > wrote: > > Wrenches, > > Does anyone have any best pract

Re: [RE-wrenches] #2 -#8 AWG Crimpers

Hi Khirpa, We use a high quality mini hex crimper with rotatable dies for #8-1/0 AWG. It is basically a miniature version of the Hex-Crimp battery lug crimper sold by Quick Cable. The one I have is older and no longer has the manufacturer label, but I believe it was marketed as a Cub Crimper. A

Re: [RE-wrenches] Integrating with Lightning Protection

Depending on your lightning rat of incidence would determine what would work best. I have used Heary Brothers in NY for almost 20 years now check their website out. They have a device that is called an "early stream emission device" that comes with a lifetime $10 million guarantee policy that you

Re: [RE-wrenches] Integrating with Lightning Protection

Hi: I really like the very thorough lightning protection guide they have available for download. Here's the link http://www.dehn-international.com/sites/default/files/uploads/dehn/pdf/blitzplaner/bpl2015/lpg_2015_e_complete.pdf Thanks for the referral Brian. JARMO _

Jay, I haven't checked there in a while but I just took a look. The crimper I'm talking about is identical to the Junior Crimper sold by Del City. -Luke On Jun 4, 2015, at 1:13 PM, Jay wrote: > Have you checked Del City? > > Jay > Peltz power > > > Luke Christy NABCEP Certified PV Insta

Re: [RE-wrenches] Integrating with Lightning Protection

Have you looked at NFPA 780-2011, standard for the installation of lightning protection systems as mentioned in 250.106? I recently read somewhere else that any conductive material in contact with or in the vicinity of a LPS has a negative effect on the designed efficiency of the LPS, but have

[RE-wrenches] #2 -#8 AWG Crimpers

Kirpal asked about a lug crimp tool in the smaller sizes. I like my ILSCO ILC-10-N since it can be squozed with one hand especially in #6 heavy lugs or smaller. Hold things in position with one hand & squoze with the other. The handles are cushioned; tool length is about one foot long tip to tip; i

Re: [RE-wrenches] #2 -#8 AWG Crimpers

Luke, Mick Jay.Thank you for the feedback..I just ordered a set of the cub crimpers...I think it is going to be a useful addition to our tool chest. What prompted this is that we often solder our ring terminals on but it tends to stiffen the copper wire.We use alot of the Midnite panel mou

Re: [RE-wrenches] #2 -#8 AWG Crimpers

The breaker post weakness came up on the list a couple of years back, and Midnite responded by switching to the sturdier post. I haven't tried the 300 v versions though. I also haven't kept up with what Outback is using, but that post design should have never been used on anything beyond stra
