zappi operation and installation manual 23
Configuration
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 (page 32) 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
zappi
(including
myenergi
devices).
The Battery setting in the Supply Grid menu is used to configure how the
zappi
will operate
alongside the battery system. See Battery Storage Systems (page 32) 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.
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.
Note: Different CT Types cannot be in the same group, the group names make this clear.
Only the first 4 groups can be used for current limiting, see Group Limits below.
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.
Group limits should be set only on the master device. See Linking Devices (p24) 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).

eSense Input
The eSense input can be configured to automatically activate a Boost during ECO or ECO+ charging, whenever economy tariff
electricity is available. The eSense input must be wired to a circuit which is live during the economy tariff times for this to
function. See
eSense Input (economy tariff) page 34 for wiring details.
eSense Setting Description
Disabled
eSense input is ignored
Boost
If the eSense input is live,
zappi
will boost the charge

zappi
will boost the charge if eSense is live AND the boost timer is set to operate at that time.
