Introduction
harvi
is a clever little device that enables
myenergi
devices
to be installed without using a
directly connected current transformer (CT) for measuring the grid and/or generation power
- instead the CT is connected to
harvi
. No power source is needed for
harvi
- the energy
harvested from the CT is used to transmit the measurement signal to your other
myenergi
device. This means batteries or separate power supply are eliminated.
Step 1:
Installation
Before you start…
harvi
can be wall mounted
harvi
can have up to 3 CT’s connected
Multiple harvi devices can be used on one site
Batteries or power supply NOT required
1.
Ensure the CT is securely clipped around the cable to be monitored - make sure the
arrow sticker on the CT is pointing in the direction of normal current flow (normally
towards the consumer unit).
2.
There is a cable grip installed on the back of the
harvi
. Simply pass the CT wire
through the top hole and then push down to lock into place.
NOTE
It is not G100 compliant to connect the grid CT to a
harvi
in conjunction with a
zappi
