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
