The diagnostics defined
inspections for troubleshooting Internet connectivity.

further guidance.
1. Verify Blue LED Indicator Light
•
Verify Internet LED illuminates on the inverter front
control panel when Internet CAT5 cable is con-
nected. If the blue Internet light does not illuminate,
follow the steps below.
2. Verify Separate Field-Installed CAT5 cable
•
Verify CAT5 is connected correctly at the home-
owner's router to each inverter on site (each
inverter requires its own Ethernet Cable from the
router).
NOTE: Ethernet cables cannot be installed within the
same raceways as the power conductors and should
always be installed independently from all power wiring.
3. Verify Correct Ethernet Ports
•
Verify correct Ethernet port at router.
•
Verify correct Ethernet port at inverter underneath
the REbus DC disconnects.
4. Verify "Hot" Signal on CAT5 Cable
•
Ensure other devices in the home can connect to
the Internet over Wi-Fi, etc.
•
If there is no signal to other devices, the home-
owner's modem and router may need to be reset.
Otherwise, the homeowner may need to call their
Internet service provider to verify service.
•
Once service has been verified, use a data tester
or laptop computer to verify Ethernet signal passes
on cable.
– Use a data tester to check whether the RJ45
male connectors pass from one end of the cable
to the other.
– If using a laptop, leave the CAT5 cable plugged
into the router, unplug the cable at the inverter
and plug into the laptop computer. Ensure the
computer is not using its Wi-Fi connection.
•
See 3-4. Remake the RJ45 male connec-
Figure
tors on the CAT5 cable if necessary. RJ45 male
connectors often need to be remade. Ensure
proper configuration of CAT5 pairs into both RJ45
male connectors. T-568B configuration is most
common.
5. Verify REbus Beacon Device Page
•
Verify the Beacon Device page appears on the
inverter screen using the arrow keys on the inverter
control panel. The Beacon will have its own device
page like the Inverter, PV Links, and PWRcell Bat-
tery regardless of whether there is an Internet sig-
nal. It is connected to the inverter via USB.

below, detail common
for
– If there is no device page for the Beacon see
troubleshooting step 2 below.
•
Verify on the Beacon itself whether two small lights
are lit (one green, the other amber) on either side
of where the blue Ethernet patch cable plugs in at
the top. These will illuminate when the Beacon is
receiving an Ethernet signal from the router and
USB power from the inverter.
•
The lights may be illuminated without a valid Ether-
net signal if custom firewall settings are configured,
outgoing ports are blocked, or the network is con-
figured for LAN access only.
•
If the lights are not lit, there is either an issue with
the physical port (disabled on the router, link speed
mismatch, or faulty cable) or the beacon is not
receiving power.

6. Verify Server Ports
•
See Table 3-1. Verify the homeowner's Internet
service provider has the correct outgoing data
ports open to allow PWRcell equipment to commu-
nicate with Generac servers.
