OverviewMicrogeneration 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. this sensor is used to monitor excess
power and when using the special ECO charge modes, zappi will automatically adjust the charge rate in response to
available surplus.

OperationStatus ScreensEV DisconnectedThe EV is not connected to zappiIn 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).
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 DelayedThe 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.
operation and installation manual zappi9

OperationChargingThe 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 CompleteThe 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).
Restart...zappi is doing a restart sequence.
This may happen with some EVs that need to be 'woken-up' to start
charging after a pause in the charge. Charge should start
immediately afterwards, otherwise the “Charge Delayed” message
will appear.
…StoppingZappi is about to stop the EV charging
Checking...zappi is carrying out a check to make sure that the built in RCD and
“PEN Fault” protection is working before starting to charge the car.
zappi carries out this before every charge so there is no need to
manually test the RCD protection.
10 zappioperation and installation manual

OperationCharging Modeszappi has three different charging modes which can be selected simply by pressing the buttons 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.
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 although some
vehicles can charge at 11kW or 22kW on a 3-Phase zappi, many EV's have lower charge rates, the maximum
charge rate for the single phase zappi is 7kW.
The actual power can vary if the grid supply voltage is not exactly 230V.
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.
Adjusts the charge rate to limit the use of grid electricity and will pause the
charge if there is too much or any grid electricity being used (setup dependant)
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 using Min Green Level in the ECO+ Settings of the
Charge Settings menu.
The actual green contribution percentage is shown when the charge is complete or when the zappi has been
disconnected from the EV.
It is possible to charge the EV using only surplus renewable power, providing there is sufficient surplus power
available and a boost option has not been set. (Please note: The EV charging standard does not support
charging below 1.4kW)
example: when
zappi is set to a Min Green Level of 100% you will need in excess of 1.4kw (approx) of surplus
energy available to start the charge, if the surplus falls below the 1.4kw threshold the charge will pause until the
threshold is once again met, after a short delay
zappi will resume charge.
You can if preferable set the
zappi to share power from the grid and generation source to ensure a charge is
always maintained, e.g. Min Green Level could be set to 75% (using mostly surplus but will use a little grid if
needed).
operation and installation manual zappi11

OperationManual BoostThe Manual Boost function can only be used when charging in ECO or ECO+ mode. When boosting, the charge rate is
set to maximum (just like FAST mode), until a set amount of energy has been stored in the EV's battery. After which,
zappi will revert back to ECO or ECO+ mode.
This function is useful if you arrive home with an almost flat battery and would like to charge the vehicle
immediately to ensure there is enough charge for a short trip if needed.
The amount of energy boost uses can be changed in the Charge Settings/Boost menu.
button will cycle through the boost options as illustrated below:
Activating Boost1. When charging in ECO or ECO+ mode, press until BOOST is shown.
2. The boost will start after a couple of seconds and the display will show the remaining boost energy.
The boost duration can be altered in the Charge Settings/Manual Boost menu option.
Cancelling BoostThe boost can be cancelled by pressing until Cancel Boost is shown.
Smart BoostThe Smart Boost function will charge the EV with a minimum kWh figure by a set time. Smart Boost is available only
in ECO and ECO+ modes.
The Smart Boost function does not bring the battery to a certain state of charge. The target kWh is only the energy
added during the charging session.
button will cycle through the boost options as illustrated below:
Example: It's a sunny Sunday and you wish to ensure there is enough charge in the EV to get to work in the morning
(e.g. 15kWh), but in the meantime, you want to use the surplus energy from the PV system to charge the car, so you
choose to use ECO+ mode. At sunset there was only 10kWh of charge accumulated. However, because you activated
Smart Boost, and set the time you needed to leave for work, zappi automatically boosted the charge in the night to
top up the battery to the required 15kWh by 7am.
12 zappioperation and installation manual

OperationActivating Smart Boost1. When charging in ECO or ECO+ mode, press until SMART BOOST is shown.
2. The SMART BOOST icon will show including the target
time and the pre-set energy amount (7.00am and
17kWh respectively, in this example screen shot).
3. zappi will then test the EV for a few seconds, to
determine the maximum charge rate.
4. The boost will start at the latest possible time to achieve the set energy amount, if the current
charge session has already accumulated enough energy, the boost will not be required and so will not
operate.
The required energy and target time can be altered only when Smart Boost is not active. These settings are in
the Charge Settings/Smart Boost menu option.
Cancelling BoostThe boost can be cancelled by pressing until Cancel Boost is shown.
Programming the Smart Boost Values1. to enter Main Menu
2. Select Smart Boost from within the Charge Settings menu. The SMART BOOST screen is then shown.
3. The boost can now be edited: Use or buttons to edit the target time and amount of charge (kWh)
that is required
4. to move to the next value, and the to return to the main screen once the required Smart
Boost parameters have been set.
operation and installation manual zappi13

OperationBoost TimerWhen using ECO or ECO+ charge modes, zappi can be programmed to 'boost' the current charge at certain times.
When boosting, the charge rate is set to maximum (just like FAST mode), regardless of the amount of available
surplus power. This means that power may be drawn from the mains grid supply during boost times.
•There are four editable time slots which can be set to operate for certain days of the week.
•Setting the duration to 0h00 will make the boost inactive.
Programming Boost Times1. to enter Main Menu
2. Select Boost Timer from within the Charge Settings menu.
The BOOST TIMER screen is then shown.
3. The boost can now be edited: Use or buttons to highlight
the time slot you wish to change. The screen below shows the
start hour being edited:
4. buttons and then press
to move to minutes.
5. again to
day (Sunday) will confirm the boost time slot and whole line will
be highlighted again.
6. to exit the BOOST TIMER screen.
Economy Tariff BoostingBoosting only when economy rate electricity is available can be achieved in one of three ways:
1. By setting the boost timer to coincide with the economy tariff times. This option should be used only if
the electricity meter is a dual-rate meter (modern meters usually are).
2. Boost only at set times AND if economy rate electric is available.
3. Automatically boost whenever the economy tariff rate electricity is available, regardless of boost times*
*Options 2 and 3 are available only when using the eSense input.
For option 1, the eSense Input in the Advanced menu should be set to
Boost Timer Enable.
With the Boost Timer Enable function set, the BOOST TIMER screen
will include an extra column (see screenshot). The e can be toggled
on/off, if e is present, the boost will activate only when the boost times
are valid and the economy rate tariff is available.
Alternatively the eSense input can be used to activate the boost
whenever the economy tariff rate electricity is available, regardless of boost times (option 2). To do this, the eSense
Input option in the Advanced menu should be set to Boost. When using this option, the Boost Timer is not needed.
Boost Time ConflictsIf one or more boost times conflict, the boost will follow the latest time or longest duration.

OperationLock Functionzappi can be locked from unauthorised operation. The Lock Function requires a PIN number to be entered before
the unit can be operated.
The lock can be set to be active
–Only when the EV is plugged in.
–Only when the EV is unplugged.
–All the time.
The settings for the Lock Function can be found in the Other Settings/Lock Function menu option.

Auto Hide If set, this will hide the main display of the zappi to keep the power readings private
Note: To set the lock so that it is always active make sure that both the ‘EV plugged’ and ‘EV unplugged’ options are
both set to ON.
Socket LockFor untethered units only, the EV cable will be locked automatically when it is inserted into the zappi, even if it is not
plugged into the EV. A small ‘lock’ icon will be seen on the right side of the zappi, in the centre of the screen. When
the EV is disconnected, a press of the button, will unlock the cable for a duration of 5 seconds, allowing the
cable to be removed from zappi. After this time, the lock will be re-activated.
If the ‘Lock Function’ (PIN lock) feature is enabled in the zappi, the cable will be not locked into the socket until the
PIN is entered and EV charging starts. This means that if anyone plugs their cable into the zappi but they do not
know the PIN they are able to remove their cable.
In all cases the cable is unlocked if zappi detects a fault or the power supply to the zappi is switched off.

Compatibility
Mode…
Active: When set to “on” the zappi will adapt to EV's with poor power factor
Min PWM: Controls the Pilot PWM minimum limit.
Power Factor: When Acve is “on” the measured power factor must be beer than this set
value to enable lower charging current set by Min PWM
End Charge Delay: Charge Complete status is delayed by this me to allow access to the vehicle
without starng a new charge session
Infinite PWM: Keeps zappi ready to restart charge aer charge is complete – this is needed on
some EV's when the user wants to preheat the vehicle in morning
Earthing: Enable or disable the PE conductor checks. To be set according to the earthing
arrangement in the installaon (TN/TT or IT)
Ireact: Reacve current drawn by the vehicle (reading only)

Configuration SettingsAll settings are described in the Main Menu section, however, the more commonly altered settings are described in
more detail below.
Time & DateThe date and time are used for the Boost Timer and the savings calculations and therefore should be set correctly.
In the event of a power-cut, and providing you have a hub and have set the zappi to “set from cloud” the zappi will
update the time and date automatically so when power is restored the clock will not need to be reset, if no hub is
connected the zappi will keep track of the date / time for approx 48 hours.
Time is always in 24-hour format but the date format can be changed.
zappi will automatically adjust the clock for Daylight Savings Time (DST) as long as Auto DST is enabled and the
correct time zone is selected.
Advanced SettingsThe Advanced Settings menu is passcode protected.
The default passcode is 0 0 0 0 although it can be changed with the Passcode menu option.
Supply Grid - PhaseThe Phase setting is only used when installing a single phase zappi onto a 3-phase supply.
It should be set to match the phase number that the zappi is wired to so that the power measurements are correct
and that the zappi responds to the correct phase when using the harvi wireless sensor.
See Three-Phase Systems (page 37) and Supply Grid – Net Phases (page 21) for more information.
–Supply Grid Device LimitSets the maximum current that the zappi will draw (including when boosting and FAST mode). This is useful if the
supply current is limited, for instance, if zappi is connected on a 16A circuit instead of a 32A.
–Supply Grid Grid LimitSets the limit that can be drawn from the grid connection (i.e. the maximum import current or the main fuse rating).
Example: A property may have a grid supply limit of only 65A, several appliances are on, the property is consuming
12kW (52A) to supply these appliances and the user wants to charge in FAST mode. Without the Grid Limit set, the
total consumption would exceed the allowed import current and trip the supply or blow a fuse. However, with a Grid
Limit setting of 60A, zappi would temporarily limit the charging current to 8A (about 1.8kW) and the maximum
allowed import current would not be exceeded.
–Supply Grid BatteryIf the property has a static AC battery system installed, it's possible to get the zappi to work in harmony with the
system, provided a CT has been installed to monitor the battery inverter. See Baery Storage Systems (page 37) for
more information about battery storage systems.
The table below details the different settings for working with an AC coupled battery storage system:
