most regions, you do not need
to select a grid profile when
installing the C250 because it
is preset with the appropriate
profile.
However, when inter-
connecting to grids managed
by Hawaii Electric Industries
(HEI), including HECO, you
must refer to the
Commercial Design

Electric Industries
Requirements for C250

Step 2: Place the Envoy
The Envoy's power line communication signal must be "coupled" between the three phases to allow the
Envoy to communicate with all of the microinverters in the system.
a. Install a phase coupler, or wire a capacitor into the system. With either solution, install the device on
the load side of the over-current protection device.
