Thanks for sharing that Dana,
Are you required by code or the AHJ, for micro-inverter systems, to have an
additional AC d/c aside from the branch circuit breaker? (on the roof or other
location)
For these micro-inverter systems the only labeling required here, by code
(CEC), is;84-030 (1) which states... “ A warning notice of an interconnected
system shall be installed in a conspicuous place at the supply authority
disconnecting means of Rule 84-022 and the supply authority meter location.”
84-022 is generally referring to the load center main breaker. And the utility
company puts their own "WARNING: interconnected system" label at the meter.
So we don't 'have to' provide any additional info, but i think that providing
some is a good idea. As Ray pointed out, too much info can be discouraging. For
now, I have opted for these labels on the load center as the only labeling for
the system;Code required -- "WARNING Two Power Source Parallel System"
and;Optional for info -- "Grid-Connected Solar Electric System
Array Rating: 660 WDC Module Rating (each):
220 WDC"....the optional one will of course need to be replaced and updated
if/when the owner decides to add to his system.
