[RE-wrenches] large array on 200 amp service

[Jason Szumlanski]

Siemens makes a "Solar Ready" line. Whatever you plan to install, make sure
it's on the utility's list of approved devices. And...

Don't find out the hard way that your utility does not allow solar backfeed
directly to the double-lugs on the load side of the meter socket. It makes
no sense whatsoever, but we ran into one utility resisting our doing
anything in the meter can, claiming it was their domain until the
conductors leave the meter enclosure. The AHJ wasn't prepared to back us
up.

With a fusible disconnect immediately adjacent to the meter, you would
think this is the preferable interconnection method in every case from the
utility's perspective!
