Page 9: Status Screens
Menus 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 10 Menus 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: Manual Boost
Menus 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. - Page 13 Menus Activating Smart Boost until SMART BOOST is shown. When charging in ECO or ECO+ mode, press The SMART BOOST icon will show including the target time and the pre-set energy amount. zappi will then test the EV for a few seconds, to determine the maximum charge rate.

Page 21: Configuration Settings
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 you have a hub and have set the zappi to “update from cloud”, the zappi will update the time and date automatically. -

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 23: Supply Grid - Network Settings
Installation Supply Grid – Network Settings Grid Limit/Load Curtailment Sets 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 65A. Several appliances are on so the property is consuming 12kW (52A). -
Page 24: Ct Config
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 25 Monitor Monitors any load, for example a washing machine or a lighting circuit. This setting can also be used to limit current drawn by myenergi devices on a particular circuit which includes other loads. See Load Balancing / Current Limiting (page 40) for more details.
-
Page 26: Esense
Only the first 4 groups can be used for current limiting, see Group Limits below. 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. -
Page 27: Linking Devices
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 28 The screen will show DEVICES UPDATING when this is happening. Device Priorities Each myenergi device that controls a load can be given a priority. The highest priority device will be allocated surplus generation power first. Devices can also be set up to share surplus power equally.

Page 29: 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. -

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. Carefully remove fascia from the zappi by If installing a tethered zappi, you must ensure the pressing the 2 clips located at the bottom of unit... - Page 31 Installation 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. fixing to brick, use the top and 2 bottom holes (left/right).

Installation Wiring Insert mains cable through the installed cable gland (if not already done so). Strip back outer sheath ensuring all cables reach the terminal blocks (leaving a little excess). Strip back all coloured cables approx 10mm. If using hard wired CT clamps now is the time to insert these too (we recommend a specialist cable gland that can accommodate multiple cables whilst still maintaining IP integrity). -

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 37 The positioning of the Grid CT sensor is crucial, please take note of the following when deciding where best to install the sensor: The sensor can be connected to any myenergi device with a CT input e.g. the eddi, zappi (wired sensor) or harvi (wireless sensor) ...

Take particular care that the ribbon cable is not trapped between the cover and the case Ensure O-ring (seal) is firmly placed into the channel and secure the cover to the unit using the 8 screws that were removed earlier (Torque setting = 1.2Nm). -
Page 40: Advanced Installation Options
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 41 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.

Page 42: Built-In Protection
If this happens and the fault cannot be reset by pressing the button for three seconds, then please contact myenergi technical support at support@myenergi.com. Over-current If there is a problem with the equipment on the EV which charges the vehicle’s battery, too much current may be drawn from the supply. - Page 43 Built-in Protection Thermal Limit zappi also includes protection against overheating. If zappi gets too warm it will attempt to reduce the current being drawn by reducing the EV charge rate. If this happens you will see the icon on the main display. If the problem continues and the zappi's internal temperature continues to rise, then it will trip the output to the EV, and the display will show Overheating! zappi will resume normal operation once the temperature drops.
