Overview
Microgeneration systems such as Solar PV and small wind turbines are at their most efficient when the generated
energy is consumed on-site rather than exporting it to the grid. This is what we call 'self-consumption'.
zappi is a Mode 3 charging station, compatible with all electric vehicles that comply with EN 62196 and EN 61851-1
plug-in electric vehicle standards.
zappi works like any regular charging point but has special ECO charging modes that will benefit homeowners with
grid-tied microgeneration systems e.g. wind or solar generation. Two special ECO charging modes automatically
adjust charging current in response to on-site generation and household power consumption. In FAST charge mode,
zappi operates like an ordinary EV charger.
A grid current sensor (supplied) simply clips around the incoming supply cable and is used to monitor excess power.
When using the special ECO charge modes, zappi will automatically adjust the charge rate in response to available
surplus.

Display
1. Import / Export Power The power being either imported or exported from or to the grid (kW). The
direction of the arrows indicates if the property is currently importing
power (left) or exporting power (right).
The size of the arrows is proportionate to the level of power being imported
/ exported, When the property is neither importing or exporting power the
figure will be 0.0kW and there will no animated arrows. The property is then
said to be 'in balance'.
2. House Load Power The power that the property is currently using in kW. (Note: This is displayed
only when the Generation Sensor is installed directly to a CT input or a harvi
or other myenergi device)
3. Status Text The current status is displayed here (see Status Screens Page 12).
4. Generation Power The power being generated at this time in kW. (Note: This is displayed only
when the CTs are installed either hard wired to the CT inputs of the zappi or
wirelessly to a harvi or other myenergi device)
5. Lock Icon Operation lock is active.
6. Date & Time The current date and time.
7. Mode Icons These icons indicate that the import limiting is active (house), Demand Side
Response (~) or the eSense input is live (e) see page 44.
8. zappi Icon If you see wavy lines above the zappi icon, the unit is thermally limiting!
The output power is temporarily reduced.
9. Charge Mode Shows the selected Charging Mode; FAST, ECO or ECO+ (see Charging
Modes page 14).
10. Charge Delivered to EV The accumulated charge energy that has been sent to EV in this charge
session.
11. Current Charging Power When the EV is charging, arrows will show here along with the charging
power in kW.
12. Green Level of Last Charge This is the percentage of 'Green' energy for the last charge session, this is
shown at the end of a charge or when the EV is unplugged.

EV Disconnected
The EV is not connected to
zappi
.
In this example the last charging session delivered 20.8kWh of energy
to the EV and 80% of that energy came from the solar panels.
Waiting for Surplus
zappi
is waiting for sufficient surplus power from the microgeneration
system. This screen will be shown in ECO+ mode as it is only in this
mode that charging will stop if there is not enough surplus power.
The house in the centre is straight-faced as grid electricity is being
used by the house (0.9kW in the example shown).
Surplus
Enough surplus is available and
zappi
is about to charge the EV. A
timer is decremented and can be set in the charge settings (ECO+
mode only).
Waiting for EV…
zappi
is waiting for the EV to respond; the EV is not ready to accept
charge.
Charge Delayed
The charging session has
been delayed by the EV because a scheduled
charge has been set in the vehicle.
Paused…
zappi
is paused for a few seconds in order to limit the start/stop
frequency during ECO+ mode charging.
