NOTICE
The UK Government’s Electric Vehicle (Smart Charge Points) Regulations 2021 have been introduced. Please
ensure you read this manual fully before installing. Processes and features have
changed.
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.
From 30th December 2022, further regulations come into force.
To ensure all our zappis are compliant by the date the regulations come into force we will be
taking a phased approach with the implementation of certain features.
For information on how these new regulations may affect you and your myenergi zappi please
read the appended information at the back of this manual.
Appendix A – (Electric Vehicle Smart Charge Points) Regulations 2021 – Regulations as of 30th
June 2022
This Appendix is relevant to all zappis INSTALLED on or after the 30th June 2022
Appendix B - (Electric Vehicle Smart Charge Points) Regulations 2021 – Regulations as of 30th
December 2022.
This appendix is relevant to zappis INSTALLED on or after 30th December 2022.

1. Introduction
Thank you for choosing zappi. Of course, we think you have made an excellent choice and are sure you will be
incredibly happy with the features, benefits, and quality of your myenergi product.
These instructions will help you to familiarise yourself with the zappi. By reading the instructions, you will be sure
to get the maximum benefit from your 'eco-smart' device.
2. Safety
zappi is an AC EV charger, intended to be installed in a fixed location and permanently connected to the AC supply
network. It is a Class 1 item of electrical equipment in accordance with IEC 61140.
The unit is designed for indoor or outdoor use at a location with restricted access and should be mounted vertically
either surface (wall) mounted or on the dedicated pole mount supplied separately by myenergi.
The device has been manufactured in accordance with the state of the art and the recognised safety standards,
however, incorrect operation or misuse may result in:
 Injury or death to the operator or third parties
 Damage to the device and other property of the operator
 Inefficient operation of the device
All persons involved in commissioning, maintaining, and servicing the device must:
 Be suitably qualified
 Have knowledge of and experience in dealing with electrical installations
 Read and follow these operating instructions carefully
 Always disconnect the device from the supply before removing the cover
The device is not to be used by persons (including children) with reduced physical, sensory, or mental capabilities,
or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the
device by a person responsible for their safety.
zappi comes in either tethered or untethered variants. The untethered version should only be used with a dedicated
cable fitted with a Type 2 plug which is compliant with EN 62196-1 and EN 62196-2. Adaptors or conversion adapters
and cord extension sets are not allowed to be used.
Failure to install and operate the zappi in accordance with these instructions may damage the unit and invalidate
the manufacturer’s warranty.
3. Disposal
1
In accordance with European Directive 2002/96/EC on waste electrical and electronic equipment and its
implementation in national law, used electrical devices must be collected separately and recycled in an
environmentally responsible manner. Ensure that you return your used device to your dealer or obtain information
regarding a local, authorised collection and disposal system. Failure to comply with this EU Directive may result in
a negative impact on the environment.
4. Copyright
Copyright of these operating instructions remains with the manufacturer. Text and images correspond to the
technical level at the time of going to press. We reserve the right to make changes. The content of the operating
instructions shall not give rise to any claims on the part of the purchaser. We are grateful for any suggestions for
improvement and notices of errors in the operating instructions.

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.
Feature Set
 3 charging modes: ECO, ECO+ & FAST
 Optimises microgeneration self-consumption
 Works with solar PV, wind turbine or micro-hydro systems
 Economy tariff sense input

 Pin-code lock function
 Tap operated display backlight
 Built-in protection against the loss of the protective neutral and earth (PEN) conductor as required by BS
7671:2018 Amendment 1:2020(The “Wiring Regulations”)
 Ethernet connector (for local communications between myenergi devices)
 Integral cable holster (tethered units)
 Supplied with 1 x clip-on grid current sensor (x3 if purchasing a 3-phase unit)
 Illuminated display – for convenience, the display can be illuminated by simply tapping the zappi front cover.
 Integrated WiFi for connecting to internet.
 Front Lid Tamper Detection
5.1 Overview Diagram
The diagram on the next page shows the zappi as part of a complete energy management system. Other myenergi
products are shown with details of how they integrate with the grid connection and the microgeneration system.

7. WiFi Set-up
If WiFi was not available during your installation, your installer may have skipped this step. As soon as you have
WiFi availability you can connect by following the steps below.
It is important to connect your zappi to the internet to install the latest firmware and receive any future firmware
updates.
Step
1
:
Firstly, turn on the Access Point by navigating to Menu > Other Settings > Internet > WiFi > WiFi
Information
on your
zappi
device display. If Access Point is showing as “Off”, turn to “On”.
Step 2:
Once the Access Point is set to “On”, go back to the “WiFi” page by pressing the (≡) button.
Step
3
:
Connect your smartphone or computer to the myenergi access point by entering your phone or
computer WiFi Settings and searching for the network displayed with the same name as the SSID you noted down
above. Once displayed, select the network to connect.
Step
4
:
You will be prompted for a
password.
Enter the password displayed on the
zappi screen that you noted down at
step 2.

Step
5
:
You will now be prompted to create a new
password to protect the WiFi settings from being
changed by anyone else. The new password must be
at least 8 characters long and consist of a
combination of lowercase and uppercase letters and
digits.
Step
6
:
Wait 5 seconds for your password to change and the webpage to reload.
Step
7:
Once connected, you will be directed to the webpage below where you will need to select your home
WiFi network from the list in the “Detected Networks” box and type in your home WiFi’s password to connect to
your router.
Step 8:
Once complete, check WiFi is connected. Do this by navigating back to the WiFi Config Menu as you
did at Step 1. Check Status is showing as “Connected”.
NOTICE
If page doesn’t load, type
192.168.4.1 into your web browser of mobile phone browser to enter WiFi setup
screen.
NOTICE
In most cases you should leave the “Show IP Settings” option unticked.
However, if you want to give your zappi a fixed IP address then tick the
“Show IP Settings” box and fill in the extra information required.
NOTICE
Please be patient. It could take up to 15 seconds for the
connection to
take place.
