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 Information
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
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.

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.

•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.

7. Connectivity
7.1 Wireless Connection
myenergi devices use an 868MHz / 915Mhz wireless link to communicate with each other. Although this is
usually more effective at passing through walls than a standard WiFi signal, radio communication can be
affected by many factors such as:
•the distance between the devices
•the thickness of any walls that the signal has to pass through
•wall construction and insulation materials
•large metal objects such as washing machines, fridges, sinks and baths
•mirrors
•electronic products such as televisions
•other wireless devices operating on the same radio frequency
Please consider the position of your myenergi devices carefully to ensure that they operate as planned.
Although the devices work in the majority of installations and our technical support team are available to
provide help in setting up your system, we cannot guarantee the performance where circumstances beyond
our control affect the performance of the wireless link.
If you have any concerns about the wireless performance then we would be pleased to answer your questions,
but please consider that if a WiFi signal works OK then there is a very high probability that the myenergi
devices will also work without any issues.
7.2 Ethernet or WiFi Connections
zappis with the built-in vHub (identified by product code zappi-2Hxxxx and 22xxxx) are supplied with a built-
in Ethernet port (RJ45) and WiFi to connect zappi to the local network (LAN).
All myenergi internet capable devices should be connected to the internet either, via WiFi or a hardwired
Ethernet connection. This version of the zappi can also act as the “hub” between all your myenergi devices
and the myenergi server. The “hub” device MUST be connected to the internet.
harvi can only be connected using a wireless link to the Master device
NOTICE
It is not currently G100 compliant to use a
harvi
with
zappi
or
libbi
to measure Grid CT, in UK installations.
•
EV chargers and battery storage must have a hardwired Grid CT (in the UK).
When pairing devices, they will use the Ethernet link over wireless, if available.
