Re: [RE-wrenches] Has anyone had Magnum Energy PT-100 controller failures

[Starlight Solar Power Systems]

Perhaps I should rephrase my question: Has anyone else been selling the PT-100? 
If so, how many? Any failures?
Early on a tech told me that I’m the only one experiencing the failures.

Hello Battery Wrenches,

I have installed about 35 of the Magnum PT-100 charge controllers since 
November 2015. I have had about 10 fail, another one just today. The problem we 
have is the same every time: network communications fail which causes other 
problems until you remove the network cable from the controller. The controller 
functions fine otherwise.

Some failed upon installation, some after a few weeks, others have lasted 
several months. Magnum has been making changes to the controller to try and fix 
it.  Has anyone else had a PT-100 failure? 

Thank you,

Larry

Re: [RE-wrenches] Protecting Asphalt Shingled Roofs

Our crew wear CougarPaws boots when working on asphalt shingles.  Very
gentle on the roof and added traction is a great safety improvement on
steeper pitches.  They seem to run 1/2 to 1 size larger than the normal
boot for most of the crew.

Re: [RE-wrenches] Protecting Asphalt Shingled Roofs

[Chris Worcester]

We get enough garden hose up to the roof to be able to spray down our work area 
quickly, about every 15 minutes during the heat waves. It can almost be a full 
time job for one person. I hadn’t thought about a mister/drip system….hmmm…

What kind of hose set up do you use?  We do too, during the hot months, but now 
you have me thinking about a rooftop drip irrigation system!

Hi James,

 

Great topic! Minimizing roof wear and tear during installation is a big deal. 
We have Yellow Spaghetti mat 
(http://www.bestmaterials.com/PDF_Files/yellow-spaghetti-datasheet.pdf) and 
carpet scraps. Each has pros and cons. Spaghetti mat is durable and we use it 
over and over. It does get slippery when wet and doesn’t have good enough grip 
over ~ 26-30 degree pitched roofs. Carpet actually performs better when wet but 
it gets heavy and messy. We can also use carpet on steeper roofs where we 
actually tie it off to our anchors by making a hole in the top of the carpet 
piece and tying a rope to it. 

 

It takes a lot of perseverance to get crews to consistently protect the roof to 
the level that is required to minimize damage. It has to be part of every 
installation plan just like fall protection.

 

On hot days we try to get on the roof as early as possible and off the roof by 
the time the roof gets warm and soft. One of my colleagues mentioned that they 
would spray a roof down with a garden hose to cool it off on hot days, I  
haven’t personally tried that.

Aloha Team Wrenches,

 

How are we best protecting asphalt shingled roofs during the install?

 

Does anybody use "yellow spaghetti mats" up on pitched roofs with any success?
