1. Electric Vehicles (Smart Charge Points) Regulations 2021
From 30th June 2022, any EV charger installed in a private setting i.e. home or workplace
NOT public, in England, Scotland and Wales has to meet the Electric Vehicles (Smart Charge
Points) Regulations 2021.
1.1 Purpose of the Regulations
The new smart charging regulations are a huge, positive forward-step by the UK Government in preparing our
homes and businesses for a smart, connected and democratized energy system. Essential tools in driving down
emissions and a core reason why myenergi exists.
The regulations are focused around when you are charging an EV. The aim of the regulations is to prevent
everyone charging at the same time and putting too much demand on the grid.
1.2 What’s changed with zappi
New features have been added to zappi to ensure our products remain compliant with UK Regulations.
These include:
Set-up Wizard – There is a simple wizard for installers to follow at start-up.
See example below:
Date & Time – Allows the zappi to know if it is being installed on or after 30th June 2022. If it is then smart
regulations must apply.
First Device – If this is your first myenergi device the zappi will opt to set the device as Master and turn the
in-built vHub on. If you are adding to an existing myenergi eco-system, the device will opt to set as slave and
turn the in-built vHub off.
Geographic location of installation – If the device is being installed outside of England, Scotland and Wales
the Smart Regulations don’t apply.
Randomised Delay – At the start of a charge and end of a scheduled, Timed Boost there will be a delay
of up to 10 minutes before your vehicle starts and stops charging. This could be a few seconds or it
could be up to the full 10 minutes. This is necessary to ensure everyone does not overload the grid by
starting to charge or ending a charge at the same time. The Randomised Delay can be overridden, if
necessary (See 1.3.2 for further details).
Smart Scheduling – To comply with the smart charging regulations your zappi will be set to charge in
off-peak hours by default. This is between 00:00 – 08:00. You may change this schedule at any time if
you would prefer to charge in peak hours or your electricity tariff off-peak hours differ from those set.
Default to ECO+ mode – If Smart Regulations apply, zappi will default to ECO+ mode on first boot up.
Charging logs – You will now be able to view a record of charging logs from the past 13 months. See
Charge Logs section below for further information.

Page 4of 24
1.3 Randomised Delay: How it works
As mentioned above, Randomised Delay will put a completely random delay at the start of a charge and end of
a scheduled, Timed Boost, for up to 10 minutes. This can be overridden by the customer in situations where
they are in a hurry.
1.3.1 Delay Status
You will be able to see if your charger is in a state of delay at any time as it will be displayed on both the zappi
screen and in the myenergi app.
1.3.2 Overriding the delay
To override the delay simply press the ‘+’ button on the zappi or press the ‘charge now’ button displayed in
the pop-up message within the myenergi app. If the delay is overridden your charge will start/stop
immediately.
You cannot permanently override the delay function. If you wish to override the delay each time you charge,
you will need to follow the above instruction to override on every applicable charging session.
1.4 Smart Scheduling: How it works
As summarised under section 1.2 your zappi will be set to charge in off-peak hours by default from initial
start-up.
1.4.1 Off-peak hours
Off-peak hours are usually between 00:00 – 08:00, depending on your specific tariff, this is when your
electricity will be at it’s cheapest.
1.4.2 Reason for Smart Scheduling
Encouraging you to charge in off-peak hours prevents overloading the grid in peak times.
1.4.3 Benefits of Smart Scheduling
Smart Scheduling will can help you spend less on yourelectricity. By charging in off-peak hours your electricity
tariff may be cheaper.

Page 5of 24
1.4.4 Changing the set schedule
If the default schedule does not suit your requirements, or your electricity tariff’s
off-peak hours differ from the schedule set, you can amend your schedule at any
time from the zappi menu or within the myenergi app.
To adjust your schedule in the app navigate to the ‘Set Boost Parameters’ option,
select start time and set the number of hours you want your charger to boost for.
To change the schedule on your zappi device navigate to ‘Charge Settings >
Boost Timer’ and amend the schedule as desired. For further information see the
Timed Boost section of the User Manual.
Alternatively, the schedule may be deleted altogether, if required. To do this
ensure all inputs are set to 00:00 for each day of the week.
1.5 Defaulting to ‘ECO+’ Mode
As mentioned in section 1.2 if your zappi meets the Smart Regulation parameters it will default to ECO+ mode
upon first start-up. This can be changed to ECO+ or FAST mode at any time by the customer. See Charging
Modes section of the User Manual for further information on modes.
1.5.1 Manual Boost
If you choose to remain in ECO+ mode you can still charge from the grid at any time by doing a Manual Boost.
Refer to Manual Boost section of the User Manual for further information on this existing feature.
1.6Charging Logs
Providing your zappi is internet connected and you have registered your device in myaccount you will be able
to view a record of charge logs for the last 13 month period. This function will begin from 30th June 2022 so
the earliest time you will see the whole 13 months will be from July 2023 or 13 months from when your device
was connected to the internet. The charge logs will tell you when the charge started, when the session ended
and the duration of each session.
To view your logs log into your account at https://myaccount.myenergi.com/login
Navigate to “My Energi Usage” in the left hand menu. The charge logs will be displayed like to example below.

Page 6of 24
1.7Installer Requirements
It is the responsibility of the installer to ensure they are compliant with Electric Vehicles (Smart Charge Points)
Regulations 2021. This includes, but is not limited to:
Installing only compliant charge points in private installs from and including 30th June 2022.
Answering the start-up wizard questions accurately to reflect actual install parameters.
Keeping a register of sales from and including 30th June 2022, for a minimum period of 10 years.
Having a Technical File and/or Declaration of Compliance available if requested by the customer
(myenergi’s Technical File and Declaration of Compliance is available at:
https://myenergi.com/guides/smart-charge-point-regulations-explained/

5. 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.

7.3 Status Screens
7.3.1 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.
7.3.2 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).
7.3.3 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).
7.3.4 Waiting for EV
zappi
is waiting for the EV to respond; the EV is not ready to
accept charge.
7.3.5 Charge Delayed
The charging session has been delayed by the EV because a
scheduled charge has been set in the vehicle.
7.3.6 Paused

Page 14 of 24
zappi
is paused for a few seconds in order to limit the start/stop
frequency during ECO+ mode charging.
7.3.7 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.
7.3.8 Charge Complete
The EV is fully charged.
The chargeenergy used during thelast charge isdisplayed at the
bottom right (20.0kWh in this case) and the 'green contribution'
is also shown (40% in this example).
7.3.9 Restart
zappi
is performing 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.
7.3.10 Stopping
zappi
is about to stop the EV charging

Page 15 of 24
7.3.11 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.

Page 16 of 24
8. Charging Modes
zappi has three different charging modes and a “STOP” mode which can be selected simply by pressing the
and buttons when the main screen is showing. The charge mode can be changed before or during a
charge. Regardless of the charge mode, all the surplus electricity is used zappi’s special ecocharge modes limit
the amount of grid electric used. Below is the explanation of each charging mode.
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 dependent on the EV's onboard charger and the grid supply
voltage. Some vehicles can charge at 11kW or 22kW on a 3-Phase zappi, but many EV's have lower charge
rates. The maximum charge rate for the single phase zappi is 7kW.
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. 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 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 (Set-up 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, if 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 inexcess of around 1.4kW of surplus energy available to start the charge. Ifthe 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. If preferable, you can set the zappi to share power from the grid and a
generation source to ensure a charge is always maintained. For example, the Min Green Level could be set
to 75%. A charge will then start when there is a surplus of 1.05kW, taking a further 0.35kW from the grid. It
is worth noting that this is only required to start a charge. If a higher amount of surplus becomes available it
will be consumed, resulting in less being drawn from the grid.
The output from
zappi
is turned off
In STOP mode
zappi
will not charge your EV. This includes the boost modes and timed boost.
zappi
will
continue to measure power and communicate with the other myenergi devices.
FAST
ECO
ECO+
STOP

Page 17 of 24
9. Manual Boost
The 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 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 delivered to the EV during the boost charge can be changed in the Charge
Settings/Boost menu.
When in ECO or ECO+ mode, each press of the button will cycle through the boost options as illustrated below:
