4.2 Z Wave Energy Monitoring Installation (Optional)
In addition to collecting data from the system microinverters using power
line communication (PLC), the CP-GWY-100 allows for communication with
select devices over a Z Wave link. The most common application for this is
for energy monitoring with the Aeotec Gen5 Home Energy Meter
(ZW095-A). It allows for the Chilicon system to support production and
consumption monitoring as well as zero export. The Gen5 uses a series of
current transducers which are placed on the power lines to be monitored.
While these transducers must be physically placed on the lines, Chilicon power recommends first pairing the units
with the CP-GWY-100 gateway. This ensures that they are in range of each other with a strong enough wireless
signal. If a weak signal is detected, the ZW117 repeater can be deployed to extend the distance.
To pair the devices:
1)
From the home screen, press the Menu button and then the Advanced Settings.
2)
Press the “Measurement Setup” button.
3)
Enable the Z-Wave communication hardware on the Gateway if that has not been done yet by checking the
box labeled “Enable Z-Wave communication”. A dot inside the box indicates it is active.
4)
The next step is to add the HEM to the list of paired devices. Press the “Add” button and then press the button
on the back of the HEM device once.
5)
If your meter has been successfully paired to your network, its light will remain solid. If the pairing was
unsuccessful, the light will blink. If that is the case, try repeating the procedure again.
6)
Once the HEM is paired, you will be prompted to specify the number of clamps used (usually it will be 2) and
whether the HEM is used for generation metering (PV array only) or consumption (net home metering or any
home appliance).
7)
After exiting that window, the new paired device should show up in the list of paired devices. Note that each
HEM is associated with an ID number.
8)
The next step is to finish the setup of the meter. Press the “Auto-Setup Meter” button in the bottom left. This
will automatically setup the meter either as a NET METER or as a PV METER. A dialog box will prompt for that
choice at the end of the setup. Note that most users will choose the NET METER option since that enables
consumption monitoring while the PV array monitoring is accomplished by the microinverters themselves. The PV
METER option is only in the case you have an additional meter setup solely for the purpose of measuring a
generating solar array. This is redundant with the monitoring of Chilicon microinverters and would only be used
to monitor should there be a pre-existing array with another manufacturer’s equipment.
9)
Finally, install the CT clamps on the actual lines to be monitored. Please note that both the Aeotec Gen5
ZW095-A Home Energy Meter and the ZW117 repeater require 120V AC power to operate.
