AC Combiner Box Installation
NOTE
: With Mobile Connect, the Envoy initially reports to Enlighten every five minutes for 12
hours or until the Envoy-S detects the expected number of microinverters, which is based on the
number entered in
Total Number of PV Modules
in Enlighten. After that, the Envoy uses low
bandwidth reporting mode. Low bandwidth mode reports 15-minute interval readings and event
data to Enlighten four times a day rather than every 15 minutes as with other connection
methods.
Method C: Ethernet Cable
To use this method, you need an Ethernet cable and a broadband router. In the box with the Envoy-S is a
ferrite bead. You must attach this ferrite bead to your Ethernet cable to ensure there is no communication
interference between the Envoy-S and other devices. To install the cable and ferrite bead:
a.
Select an Ethernet cable with unshielded twisted pairs (UTP) and suitable ratings for its environment.
Do not use shielded twisted pair (STP) cable.
b.
Place the bead on the cable, near one end, and close the latch.
c.
Plug the cable end with the ferrite into the Envoy-S Ethernet port.
d.
Secure a tie wrap on the cable on each side of the ferrite bead.
e.
Tighten an additional tie wrap around the ferrite bead.
f.
Trim any tie wrap excess.
g.
Plug the other end of the Ethernet cable into a spare port on the broadband router.
Within three minutes the Network Communications LED
lights solid green, indicating a
successful connection to the Internet and to Enlighten.
When you use Ethernet cable, two small LEDs on the Ethernet port indicate Ethernet link and activity.
The link LED is solid green when the cable is connected correctly, and the activity LED flashes green
or yellow when data is sent or received.
Method D: Power Line Communication Bridges
(Order EPLC-01 separately)
If you need to locate the Envoy-S away from the router, at a distance where an Ethernet cable is not practical
or the wireless signal does not reach, use power line communication bridges with the Envoy-S. Bridges allow
the Envoy-S to communicate with the broadband router over the site’s power lines. To install power line
communication bridges:
a.
Plug one of the bridges into the same AC outlet that the Envoy-S is using.
b.
Place the bead on the Ethernet cable, near one end, and close the latch. Do not use shielded twisted
pair (STP) cable.
c.
Plug the cable end with the ferrite into the Envoy-S Ethernet port.
d.
Secure a tie wrap on the cable on each side of the ferrite bead.
e.
Tighten an additional tie wrap around the ferrite bead.
f.
Trim any tie wrap excess.
g.
Plug the other end of the Ethernet cable into the bridge.
h.
Plug the other bridge into an AC outlet near the broadband router.
i.
Connect one end of a second Ethernet cable to the second bridge, and connect the other end of the
Ethernet cable into the broadband router.
Within three minutes the Network Communications LED
lights solid green, indicating a
successful connection to the Internet and to Enlighten.
