Jeff:
Would a class 320, solar-ready, meter/main combo be approved for this commercial application? Here is a link <https://www.downloads.siemens.com/download-center/download?BTLV_44465> to a product we have used in residential applications. It offers through-the-jaws metering at 400 amps peak, 320 amps continuous.

Hey Jay, Yes so you were on to it - but with the addition of having that downstream of a separate 200 AMP meter box and 200 A Main that works :) Otherwise PG&E would call it a 400 Amp service which for commercial accounts means having to have CTs for the metering. Thanks!, Jeff Jay wrote on 10/17/19 3:38 PM: 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?

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.

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!
