Install the Meter
Using the
screws provided in the meter kit, attach the
mounting plate to the inside of the main
distribution board or to another surface. Choose a
location that takes into account the voltage line
harness and CT cable lengths.
On the
voltage line harness, combine the blue and red leads
as shown below.
Plug the
voltage line harness into the meter.
Connect
the voltage line harness leads to a dedicated two
pole circuit breaker (not exceeding 20 A):
Voltage Harness Phase and Wire
Color
Breaker Terminal
A (black)
L1 (Phase A)
B (red)
L2 (Phase B)
C (blue)
Spliced with the Red B
wire
N (white)
Neutral busbar
Note
If
a dedicated circuit breaker is not available, the
voltage line harness can be spliced to existing
15-20A breakers.
Note
Ensure the breaker phases align with the supply
phases. Some models cross phases so that the
breaker is the opposite phase of the supply lug
above it.
Install the
Antenna
To install the antenna, screw it onto the meter. It is recommended to
locate the antenna outside the enclosure using the included antenna
extension:
Locate a
1/2” or 3/4" knockout and install a cable
gland.
Mount the
antenna by threading the extension cable through the
included knockout mount and securing the mount.
Screw the
antenna onto the extension cable and connect the
extension cable to the meter.

Install the CTs
Note
For each CT,
ensure the CT is installed with the label SOURCE THIS SIDE on the CT housing pointing
toward the power source (service entrance / grid for Site
CTs, solar inverter for Solar CTs). Always verify CTs are in
the correct orientation by observing power flow in Tesla One.Figure 2. CT
Orientation in Relation to Power Flow
Warning
Before installing,
disconnecting, and/or adjusting CTs, ensure the circuits
being measured are not energized and the system is
completely powered down. Failure to de-energize the system
may compromise operator and equipment safety.
Install
the Site CTs upstream of all loads and
generation:
Plug the CT measuring L1 (Phase A) into the CT1
or CT4 port on the meter.
Plug the CT measuring L2 (Phase B) into the CT2
or CT3 port on the meter.
Clamp the CTs around the L1 and L2 conductors
where Site is being measured.
Install a Solar CT around
the Solar Inverter conductor:
Plug the CT into a port on the meter.
For L1, plug the CT into the CT1 or CT4 port
For L2, plug the CT into the CT2 or CT3 port
Clamp the CT around the appropriate Solar
Inverter conductor based on the port it is plugged
into.
Note
Only one CT is required to measure Solar because
total power output is calculated by the software.
This CT is configured as 1CTx2.
