Are they generating at 120/240 or 277/480 volt? The 2 big PV systems I saw one was gen 400 amps and 480 volt 3 phase. The second one will gen 600 amp at 240/208? when it is done.
These are 277/480 volt units. I'll check the file for the design info when I get a chance. As I said above, this was a landlord install, and they are keeping the data close to their chests.
