Re: [RE-wrenches] Solar Edge Experience?

2014-05-05 Thread Erika Weliczko
No trunk cable is bonus. Working with regular PV cable is easier on stocking 
materials. 
Safe working voltage is real bonus and makes testing during installation 
reasonable. 

Strings over 12 is bonus. Sometimes, 16, 18+ makes sense physically. Now it can 
make sense electrically. With different solar exposures. 

Still needing to use metal conduit inside is sometimes a hassle, but MC cable 
makes it doable. 

No way to test communication with optimizer until DC voltage is applied. This 
means if you have a DOA optimizer that reads correct voltage, you are removing 
modules to get to an optimizer. That is a drag. Support is pretty good. 

The new 7kw inverter matched to 40a OCP to max out residential 200A panel 
backfed breaker sounds good.

Re: [RE-wrenches] Electric fence, metal buildings, lightning protection systems

2013-12-06 Thread Erika Weliczko
SB3000TL-US inverters.

The concern is possible voltage that may lead the inverter to believe there is 
a ground fault because of fence connections.

I wonder what the tolerable window of voltage of + or – to ground is for this 
unit before it cries GF.

 

During a drizzle I had a little tingle while assembling EMT. I did not get a 
meter out, but it sorta felt like a 9V battery across your tongue. 

In the end even a little tingle is not really supposed to be there…

[RE-wrenches] Utility inverter rating

2012-10-18 Thread Erika Weliczko
Greetings all.

I recently received this back regarding an interconnection application
proposing a Sunny Island 6048 and a SB7000:

"we have to rate the system at the max output of the inverters, and since
that battery backup has an inverter that can export 11kW, (albeit for 3
seconds) I have to review the system for a total of 18kW."

 

This is a new one on me. I might argue that the SB7000 is upstream of the
SI6048 and really the SI6048 is the point of interconnection, so the SB7000
is irrelevant. And 3 seconds is not really continuous operation.

 

It seems that batteryless inverters show continuous output ratings, though I
know there are some that specify a larger than expected OCP for various
reasons, but that is not what the utility cares about.

Any insights here? 

 

Thanks,

Erika

Re: [RE-wrenches] Combating requests for itemized PV pricing

2012-08-18 Thread Erika Weliczko
I find the rough percent breakdown as you suggest is useful in getting them to 
understand that they don't need those numbers or an itemized BOM before they 
agree to do a project. There are many customers that think if total cost is X 
and modules are Y that the cost to install is REALLY expensive at X-Y. 
If we were selling itemized lists, I'd be running buysolarcraponline.com, so I 
refrain from providing lists. My contract is for a total sum. 
If the prospect does not want a turnkey solution, then they are not a good fit 
for those of us that provide these products and services. And that is OK. 
Some days are easier going down this road than others.

Re: [RE-wrenches] Expansion joints

2011-03-31 Thread Erika Weliczko
http://www.steelconduit.org/pdf/ConGuide.pdf

page 16

 

The NEC does not directly dictate when expansion coupling are required for
EMT.

300.7 merely says to accommodate for expansion. 

If PVC requires it for ¼ in of movement and you extrapolate, then 100ft of
steel conduit exposed to a 35 degree temperature difference would require an
expansion coupling.

 

I’m counting on about 100-120 degrees of temperature difference for steel
conduit on a rooftop. That’s 32 or 26.6 ft of pipe, respectively.

Does anyone have information (manu and part number) for expansion joints for
1-1/2 EMT? I have also heard that many EJs are designed for rigid conduit
(RMC) and may not be directly applicable to EMT.

Re: [RE-wrenches] Expansion joints

2011-03-30 Thread Erika Weliczko
I recently used a Hubbell Killark product for rigid/IMC and was not happy with 
how the threads of the coupling engaged in factory conduit threads.

 

Crousehinds XJG-EMT series is intended for EMT. And is described as being used 
indoors or outdoors. The EMT couplings mostly seem to be compression.

Peter,

 

Cooper makes one for 1.5" emt, not sure if it is rated for wet locations or not.

 

part #XJG54 EMT, it allows for up to 4" max of conduit movement.

Re: [RE-wrenches] NABCEP Stamp

2011-03-30 Thread Erika Weliczko
I hate to mention the evil insurance industry. However, a stamp implies some
professional liability insurance to me.

There are other professional membership organizations (RESNET) that have
developed a tailored professional liability insurance package for its
credentialed members with a preferred vendor.
Is NABCEP looking toward this? I do not know if there is a need, but may be
an advantage under certain circumstances.

Peace,
Erika

I'm with Andrew here. If a NABCEP stamp of some kind makes the city happy
and greases your permit approval, that's OK. If it is a city requirement,
then we'd sure like to know about that. IF you do have one made, please
remember to follow the NABCEP guidelines as to the use of our "Mark". IE,
your name -not the company name and not nothing- has to appear next to the
Mark.
