Message-ID: <[email protected]> Content-Type: text/plain; charset="iso-8859-1" Hi Eric, We've used TTi, EcoFasten, and Quick Mount. I like Quick Mount the best but they are a bit pricy so we've been using Eco Fasten for the majority of our work over the last year. If anything, I've found that TTi requires more labor and is more likely to require shingle cutting plus I'm gun-shy about their material quality. That said, the majority of our standard comp shingle mounts require no shingle cutting (although you might have to remove a nail or two) with Quick Mount or Eco Fasten. You just slide them up under the shingles as pictured in this video: http://www.quickmountpv.com/training/videos/classic-comp-install.html Maybe you have a different kind of comp in your neck of the woods? If you're really worried about it you can always take a sample out and see if you can slide it under the shingles without any cutting. It just might work. Good luck. Best, August *From:* [email protected] [mailto: [email protected]] *On Behalf Of *SunHarvest *Sent:* Wednesday, August 15, 2012 4:22 PM *To:* RE-wrenches *Subject:* [RE-wrenches] Best practices for comp shingle flashing? Thanks guys. Talked with TTi and mentioned Mr. Miller's experience with rust. They said they got a lot of feedback about this problem on their 1st generation line and have since corrected the issue. I'll remain cautious...thanks Willy. TTi, DPW, EcoFasten, and Quick-mount all seem to have the same issue of lacking versatility in height adjustment. Anyway, going to check out a sample from TTi. DPW and EcoFasten look like they still require cutting of both flash base and comp courses. I'm trying to avoid cutting anything as I want to avoid disturbing original flashing and original roofing material. Thanks for all your input!!

Have a few clients that have been asking. Is it at the service, using products like this: http://www.cooperindustries.com/content/public/en/bussmann/electrical/products/surge_protectiondevice/photovoltaic_spd.videos.html I always wonder what it protects and the fine print in the event of a lightning storm to someone hitting a pole on the street and sending the surge back into the property. ?

When the generator is started, the Heart inverter kicks on and starts to charge, after about 3 seconds it kicks off, then on, then off and repeats. The voltage and frequency of the generator output look good. 120V L-N and 60-62 Hz no load. The Heart just doesn't seem to like it after it kicks on the charger. (Sorry, no scopemeter available) What is very interesting is that on the other pole of a transfer switch connected to the AC input, is a fairly inexpensive gas generator, pull start, on wheels etc. This puts out 108VAC at 59-60Hz. When connected to this generator the Heart immediately latches in and will continue charging flawlessly at 100ADC. For whatever reason, the Heart, doesn't like the voltage waveform of the Onan generator. The Fluke 87 multimeter that I was using to test, was catching some type of transient (frequency reading would shoot up to 70-100Hz) when the Heart would latch into the Onan. Other that that with my simple tools I could see no real difference between these generators, other that the 108VAC of the gas generator. Any ideas, or known compatibility issues with this equipment?

I would look to borrow for a scope or at least use a cheaper meter that can accurately report the frequency. Try slowing the generator to 59 Hz to see if the inverter likes it better.

It might be finding the voltage or frequency to high for it?s liking. Plug it directly into the generator of somewhere before the inverter to get gen power.

It's frustrating, because usually they are looking at prices for materials that either I would not consider selling, or would not meet the mounting requirements of the Florida Building Code. Of course, they do not understand and consider all of the other costs. In addition, lots of people are looking for a breakdown of prices (down to the line item - nuts and bolts). I generally refuse to provide it because it inevitably leads to the response "I can get that module/inverter online cheaper." The "I need to make money" response leads to "yeah, but you must be getting better prices than I see online" argument. And so on, and so on... I'm sure you've heard it... I've resorted recently to just providing a percentage breakdown, stating that the price is roughly 25% each: - PV Modules - Inverters and Electrical - Mounting System - Design/Engineering, Permitting, Labor, Overhead, and Profit Any other tips out there to answer the request for line item details?
