Page 10: Status Screens
Operation 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. - Page 11 Operation 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.
-
Page 12: Charging Modes
Operation Charging Modes FAST ECO+ STOP zappi has three different charging modes and a “STOP” mode 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, all the surplus electricity is used. -
Page 13: Manual Boost
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. 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. - Page 14 Operation 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. Activating Smart Boost When charging in ECO or ECO+ mode, press until SMART BOOST is shown.
-
Page 15: Boost Timer
Operation Boost Timer When 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. -
Page 16: Lock Function
Operation Boost Time Conflicts If one or more boost times conflict, the boost will follow the latest time or longest duration. Lock Function zappi can be locked from unauthorised operation. The Lock Function requires a PIN number to be entered before the unit can be operated and/or a charge is allowed. - Page 17 Operation If the ‘Lock Function’ (PIN lock) feature is enabled in the zappi, the cable will not be 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.

Configuration Configuration Settings All settings are described in the Main Menu section; however, the more commonly altered settings are described in more detail below. Time & Date The 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 the zappi has a connection to the internet the zappi will update the time and date automatically once the power is restored. -

Configuration Advanced Settings The 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 – Device Settings Phase/Phase Rotation Single Phase zappi The Phase setting is only used when installing a single phase zappi onto a 3-phase supply. -
Page 26: Supply Grid - Network Settings
Net Phases When enabled, all readings from 3-phase myenergi devices configured as 3-phase, will be netted. This means that surplus generation on ANY phase will be considered available for consumption on ANY other phase. -
Page 27: Ct Config
Configuration Export Margin This sets a minimum level of export power which is maintained when zappi is charging in ECO or ECO+ modes. Export Margin would normally be set to 0W (zero Watts) so that all available surplus will be used to charge the vehicle. - Page 28 Monitors any load, for example a washing machine or a lighting circuit. This setting can also be Monitor used to limit current drawn by myenergi devices on a particular circuit which includes other loads. See Load Balancing / Current Limiting (page 51) for more details.
-
Page 29: Preconditioning
Configuration Group Limits Current limits can be set for certain CT Groups. When a Group Limit is set the myenergi devices in the group will limit the power they draw to keep within the set limit. Group limits should be set only on the master device. See Linking Devices (page 3531) for details about master devices. - Page 30 Configuration Setting Preconditioning The preconditioning mode can set to “On” or “Off”: CT Type Function Description Once zappi detects “Charge Complete”, the next time the EV tries to draw power zappi will revert to the mode set (ie ECO, ECO+ or FAST). If zappi is in ECO+ and there is not enough surplus generation then the charge will pause and zappi will display "Waiting for surplus When preconditioning is turned ON, the amount of energy (kWh) zappi should supply to warm up the battery / precondition the EV can also be set.

Page 31: Esense
If the eSense input is live, zappi will not charge, regardless of set charge mode or a boost Linking Devices Up to six myenergi devices can be wirelessly linked together. By linking devices, you can use more of your own energy or have more control and visibility. Devices available now are:... - Page 32 Master & Slave Devices When two or more myenergi devices are wirelessly linked, one device will act as the master device. This device will control the other slave devices. Some settings can only be changed on the master device, e.g. Grid Limit and Net Phases.
- Page 33 Configuration All linked devices are listed in the DEVICES screen, the device shown in CAPITAL letters is the device currently being viewed. The serial number of each device is shown on the right The priority is shown on the left of each load controlling device with 1 being the highest priority. If two or more devices have equal priority, the available surplus (for that priority level) is shared between them.

Page 34: Wireless Connection
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. -
Page 35: Ethernet Connection
This Ethernet connection can be used as an alternative to connecting the myenergi devices using the wireless link. This version of the zappi can also act as the “gateway” or “hub” between all your myenergi devices and the myenergi server Note: harvi can only be connected using a wireless link to the Master device When pairing devices, they will automatically use the Ethernet link if available. -
Page 36: Installation
Installation Installation When installing and wiring the zappi, care should be taken to maintain the IP rating of the unit. Ensure that the grommets and bungs provided are fitted, the O-ring behind the cover is seated correctly and that the incoming power and CT cables are fitted using an appropriate size and type of gland. ... - Page 37 Installation Carefully drill a hole into the unit to match the size of your cable gland. Attach cable gland ensuring IP rating is met. Using zappi template mark mounting holes. For To maintain the IP rating of the unit you will need to add bungs (provided) to the unused holes.

Page 40: Esense Input
Installation eSense Input zappi has an “external Sense” or “eSense” input which can be used with an external input (such as a relay contact or voltage) to sense the availability of economy tariff electricity, this can be used to automatically boost the charge when in ECO or ECO+ charging modes. -

Page 42: Ct Sensor Installation
CTs can be wired to any myenergi device with CT inputs (e.g. eddi, zappi or harvi). This allows for flexible installation as a CT can be wired to the nearest device. Ideally the grid CTs should be wired to the master device. - Page 43 CTs can also be used to limit the power drawn from the supply. See Load Balancing / Current Limiting (page 5146). Additional CTs can be connected to any myenergi device with a CT input that is linked to the network (see Linking Devices on page 3331).

Load Balancing / Current Limiting / Load Curtailment CTs can also be used to limit the current drawn by myenergi devices to avoid overloading circuits; this is referred to as load balancing or load curtailment. There are four different ways to limit current and they can be used alone or combined for more complex situations. - Page 47 CT should be clipped around the Live cable of the supply feeding the diverter. The arrow on the CT should be pointing away from the diverter (towards the consumer unit). Wire the CT to the nearest myenergi device or use a harvi if a wireless connection is needed.
