Wrenches,

Please note that Enphase has completed testing and received listing for the ac connectors and the DC connectors for use as the disconnect as required by the NEC. No other disconnect device is required. This information is contained in the latest Installation and Operations manual, available for download from http://www.enphaseenergy.com/support/downloads.cfm

See ya!

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.

cheers,

benn
