13.2 CT config
The CT1 and CT2 inputs are configured depending on the connected CT sensors. The internal CT which
measures the output current also has some settings.
CT
Description
CTINT
This is the internal CT which measures the output current of the
eddi
.
CT1
CT1 input.
CT2
CT2 input.
CT Type
Description
None
No CT connected.
Grid
Grid CT monitors the import and export power of the property, this is main
control CT and there must only be one Grid CT set for each phase.
Generation Only
Monitors Solar PV or Wind generation.
Storage Only
Monitors a device that can 'store' energy (e.g. a third-party energy diverter)
and enables the
eddi
to take priority over it. The power used by the third-
party device is considered as surplus power unless the device is
intentionally using grid power (i.e. it is boosting).
The CT should be installed on the Live supply cable feeding the diverter, with
the arrow pointing away from it.
Generation & Battery
Monitors Solar PV or Wind generation that is combined with a DC-coupled
battery.
Monitor
Monitors any load, for example a washing machine or the lighting circuit.
This setting can also be used to limit current drawn by
myenergi
devices on
a particular circuit which includes other loads. See
Load Balancing / Current
Limiting
for more details.
AC Battery
Used to monitor an AC-coupled battery.
With this setting it's possible to manage the distribution of surplus energy
between the battery and the
eddi
(including
myenergi
devices).
The Battery setting in the Supply Grid menu is used to configure how the
eddi
will operate alongside the battery system. See
Battery Storage Systems
for more information.
The CT should be installed on the Live supply cable of the battery
inverter/charger, with the arrow pointing away from it.
Note:
These are the same when using CTs with the harvi device, however, they are set via the Linked Devices
menu rather than the CT Config menu.
IMPORTANT
There must be only one Grid CT set (per phase) for the whole installation.
