13.2.1
CT Groups
CTs can be put in groups so that their readings are netted. For example, you might want to monitor two solar
PV systems and see the total generation on the display. Use Group in the CT Config menu to set which group
the CT should be in.
Only the first 4 groups can be used for current limiting, see Group Limits below.
13.2.2
Group Limits
Current limits can be set for certain CT Groups. When a Group Limit is set, the
myenergi
devices in the group
will limit the power they draw to keep within the set limit. Before Group Limits can be set, devices need to first
be ‘linked’ (See section 14. Linked Devices).
Group limits should be set only on the
master
device. See
Linking Devices
for details about
master
devices.
It is possible to use more than one group limit type (e.g. IL1 with MN1, so that there are two conditions for
limiting).
Group Limit Example
Additional CT Installed
CT Config (all devices)
Limit current drawn by two
eddi
devices that are on the same 20A
supply.
None; the internal CTs are used.
CTIL
Type: Internal
Group: IL1
Group Limit: 20A
Limit current drawn by an
eddi
device that is fed from a 25A supply
which is also feeding another
appliance (e.g. a tumble dryer).
One CT is clipped around Live of the 25A
supply and wired to CT2 of the
eddi
.
CT2
Type: Monitor
Group: MN1
Group Limit: 25A
Limit current drawn by two devices
that are in a garage which is fed from
a 40A supply. A washing machine
and dryer are also in the garage.
One CT is clipped around Live of the 40A
supply to the garage and wired to CT2 of
one of the
eddi
units.
Note:
The other
eddi
does not need to
have a CT connected, but it will still need
to have a CT input configured to be in the
same Monitor group.
CT2
Type: Monitor
Group: MN1
Group Limit: 40A
Note:
Different CT Types cannot be in the same group, the group names make this clear.
