Re: [RE-wrenches] SolarReady Service Panel vs adding Supply Side connection?

2019-10-17 Thread Jay 
What about installing a 200 amp breaker in the 400 amp buss box?  

We talk a lot about doing it for smaller boxes, is there a reason it won’t work 
here?

Re: [RE-wrenches] SolarReady Service Panel vs adding Supply Side connection?

2019-10-17 Thread Glenn Burt 
Hi Jeff,

 

Seems to me if allowed in your jurisdiction, you might be best served by 
installing a new 200A fused service disconnect ahead of the existing main 
service panel. Or even a 400A one to allow for additional work inside (CT’s), 
then perform a supply side connection in it. Some manufacturers of switchgear 
have an option for lugs that accept multiple conductors, so no piercing of 
conductors needs to happen.

 

Good luck,

Glenn

Esteemed Wrenches,

I am in need of changing out an existing 200 Amp service entrance in order to 
accommodate a bus capable of handling a a 200 Amp Solar backfeed (41 KW system) 
.  

PG&E is upgrading the transformer to handle the backfeed but when I proposed a 
Siemens SolarReady 400 Amp service entrance they couldn't approve it cause 
since the building is a shop - they classify it as commercial and require a 
panel that can handle CTs when there is a 400 Amp service involved.

Anyone else faced with this have solutions?  What is the cheapest equipment I 
can provide to satisfy all requirements?

We don't need to upgrade the existing 200 amp service entrance equipment for 
load purposes - only to meet the bus requirements of backfeed.

Would it be cheaper and easier to use the existing (or new) 200 Amp residential 
panel - not call it a 400 Amp upgrade but simply add a 200 Amp Supply Side 
Connection?  Suggested equipment to do that in the most economical manner?

Any help well appreciated!

Jeff

[RE-wrenches] SolarReady Service Panel vs adding Supply Side connection?

2019-10-17 Thread Jeff Clearwater 

Esteemed Wrenches,

I am in need of changing out an existing 200 Amp service entrance in 
order to accommodate a bus capable of handling a a 200 Amp Solar 
backfeed (41 KW system) .


PG&E is upgrading the transformer to handle the backfeed but when I 
proposed a Siemens SolarReady 400 Amp service entrance they couldn't 
approve it cause since the building is a shop - they classify it as 
commercial and require a panel that can handle CTs when there is a 400 
Amp service involved.


Anyone else faced with this have solutions?  What is the cheapest 
equipment I can provide to satisfy all requirements?


We don't need to upgrade the existing 200 amp service entrance equipment 
for load purposes - only to meet the bus requirements of backfeed.


Would it be cheaper and easier to use the existing (or new) 200 Amp 
residential panel - not call it a 400 Amp upgrade but simply add a 200 
Amp Supply Side Connection?  Suggested equipment to do that in the most 
economical manner?


Any help well appreciated!

Jeff

Re: [RE-wrenches] Use roof rock as Ballast for Solar Racking

2019-10-17 Thread Al Frishman 
Has anyone used Renusol CS+ ballast racking?I found them online and there 
is a picture showing the trays being filled with roof rocks like I am 
considering.  I am having trouble getting a hold of them.   I see that there is 
a post in the archives from 2011 for an older version Renusol CS60.Anyone 
know of a contact or distributor for them?


Thanks!
