1. Choose a Location for the Envoy-S
a.
Install the Envoy-S near the switchboard. This ensures that the Envoy-S receives the strongest
possible communications signal from each microinverter.
b.
If you are installing the Envoy-S in a three-phase application, the 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. Install a phase coupler on the load side of the over-current
protection device. See the Enphase Technical Brief on Phase Coupling for your region at
enphase.com/support
.
c.
Install the Envoy-S in a protected dry space (such as a garage, attic, basement, or other cool,
dry location) and, if the Envoy-S is hard-wired outdoors, you must also install it inside an IP54-
rated, or better enclosure with conduit attachment. Use an appropriately rated enclosure if hard-
wiring indoors.
NOTE
: Metallic enclosures may impair Wi-Fi signal strength.
d.
Mount the Envoy horizontally using the included DIN rail.
WARNING:
Risk of equipment damage. When installing the Envoy-S in an enclosure,
choose area for installation where ambient temperature does not exceed 46º C.
e.
To
wall-mount
use two appropriately sized screws and a screwdriver. Mount the DIN rail first,
and then clip the Envoy-S to the DIN rail.
2. Provide a Power Connection
The Envoy-S is available in two configurations.
The
Envoy-S Standard (ENV-S-WB-230-F, -G, and -I)
includes an AC power cord.
The
Envoy-S Metered (ENV-S-WM1-230)
does not include an AC power cord, and you
must
hard-wire it.
The following sections provide separate instructions for the two configurations.
Provide Power for the Envoy-S Standard (ENV-S-WB-230-F, -G, and -I)
Use one of the following methods to provide power to the Envoy-S Standard.
Method A: Plug the Envoy into a 230 VAC Socket
The Envoy-S Standard (ENV-S-WB-230-F, -G, and -I) includes an AC power cord.
WARNING:
If the included power cord is missing or lost, you must use an equivalent power
cord. See
“
Wire / Power Requirements / Specifications
” on page 48.
a.
Locate an AC socket that is near the switchboard. If
outdoors, the socket must be appropriately rated.
b.
Plug the AC power cord into the AC inlet on the
Envoy-S.
c.
Plug the other end of the power cord into a dedicated
230 VAC socket (not a power board).
WARNING!
Do
not
plug the Envoy-S into a
power board, surge protector, or uninterruptable
power supply (UPS). The surge suppression or
filtering within these devices impedes power line communication performance. Also, if
possible, do not plug a power board into the same AC socket that the Envoy-S is using. The
surge suppression or filtering components of a power board may still interfere with
communications if they are near the Envoy-S.
