Introduction
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 SAE J1772, EN62196 and EN61851
plug-in electric vehicle standards.
zappi works like any regular charging point but has special eco charging modes which will benefit homeowners with grid-tied
microgeneration systems, like 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
charging.
A grid current sensor (supplied) simply clips around the incoming supply cable. This sensor is used to monitor excess power and
when using the special ECO charge modes, zappi automatically adjusts the charge rate in response to available surplus.

Import / Export Power The power being either imported or exported from or to the grid (kW). The
direction of the arrows indicate if the property is currently importing power (left)

The size of arrows is proportion to the level of power. 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'

Status Screens
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's 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 is this example).
Waiting for EV...
zappi is waiting for the EV to respond; the EV is not ready to accept
charge.
Paused...
zappi is paused for a few seconds in order to limit the start/stop
frequency during ECO+ mode charging.
The Start/Stop Delay can be changed in the Charge
Settings/ECO+ Settings menu option.
Charging
The EV is charging.
In this example the car is charging in ECO+ mode at 1.6kW, there is no
import or export from the grid (0.0kW) and the EV battery has charged
by 8.9kWh since the car started.
Charge Complete
The EV is fully charged.
The charge energy used during the last charge is displayed at the bottom
right (20.0kWh in this case) and the 'green contribution' is also shown
(40% in this example).

Operation
Charging Modes
zappi has three different charging modes which can be selected simply by pressing the button when the main screen is
showing. The charge mode can be changed before or during a charge.
Regardless of the charge mode used, all of the surplus electricity is used but zappi's special eco charge modes, limit the
amount of grid electric used. Below is explanation of each of the three charging modes.
FAST
Charges at the fastest rate.
Fast Mode will charge the EV at the fastest rate and will import grid electricity if there is
insufficient surplus generated power.
The actual charge rate is dependant on the EV's onboard charger and the grid supply voltage.
Typically, vehicles have either a 3.3kW or 6.6kW charger. The actual power can be a little
different if the grid supply voltage is not exactly 230V.
zappi will deliver up to 7kW provided the supply connection is suitably rated.
ECO
Adjusts the charge rate to limit the use of grid electricity.
The charge rate is continuously adjusted, in response to changes in generation or power
consumption elsewhere in the home, thereby minimising the use of grid power.
Charging will continue until the vehicle is fully charged, using available surplus power.
However, if at any time, the available surplus power falls below 1.4kW, the shortfall will be
drawn from the grid.
Note: The EV charging standard does not support charging below 1.4kW.
ECO+
Adjusts the charge rate to limit the use of grid electricity and will pause the
charge if there is too much grid electricity being used.
The charge rate is continuously adjusted, in response to changes in generation or power
consumption elsewhere in the home, thereby minimising the use of grid power.
Charging will pause if there is too much imported power, continuing only when there is enough
surplus power available.
The surplus power threshold at which the charge will start or stop can be set in the ECO+
Settings option, which is found in the Charge Settings menu.
It is possible to charge the EV using only surplus renewable power, providing there is sufficient
surplus power to do so. To do this, set the Min Green Level to 100%.
The Min Green Level is the minimum level for the contribution of green energy at the end
of the charge. The actual green contribution for the charge, is displayed when the charge is
complete or the EV is disconnected. For example: With Min Green Level set to 50%,
charging will be paused if 700W of power is being imported from the grid and will resume
charging when there is 700W of power being exported.
Note: The EV charging standard does not support charging below 1.4kW.
