Page 9: 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 10 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 11: Charging Modes
Operation Charging Modes zappi has three different charging modes 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 used, all of the surplus electricity is used but zappi's special eco charge modes limit the amount of grid electric used. -
Page 12: Manual Boost
Operation 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 back to ECO or ECO+ mode. - Page 13 Operation Activating Smart Boost When charging in ECO or ECO+ mode, press until SMART BOOST is shown. The SMART BOOST icon will show including the target time and the pre-set energy amount (7.00am and 17kWh respectively, in this example screen shot). zappi will then test the EV for a few seconds, to determine the maximum charge rate.
-
Page 14: 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 15: Lock Function
Operation 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. The lock can be set to be active Only when the EV is plugged in. –... -

This means that surplus generation on ANY phase will be considered available for consumption on ANY other phase. See Three-Phase Systems (page 37) for more details about myenergi devices on 3-phase supplies.
- Page 22 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: Installation
Installation Installation When installing and wiring the care should be taken to maintain the IP rating of the unit. Ensure that the zappi grommets and bungs provided are fitted, the O-ring behind the cover is seated correctly and that the electricity cable is fitted using an appropriate size and type of gland. - Page 28 Installation Using zappi template mark mounting holes. To maintain the IP rating of the unit you will need to add bungs (provided) to the holes not used. Use top and 2 bottom holes left/right for brick use 2 vertical holes if mounting to a stud wall or joist. Ensure O-ring is present and sits neatly into its channel.

An electric shock can be fatal; electrical connection work may only be carried out by a competent person The earth conductor must be correctly installed and reliably connected This device must be equipped with an over-current protection device of maximum 32 Amps (B32) Supply The single phase zappi should be connected to a 230V/240V nominal AC supply. -

- Page 33 CTs can be wired to any myenergi device with CT inputs (e.g. eddi, zappi or harvi). This enables very flexible installation as the CT can be wired to the nearest device. Note: The harvi device can be used (wirelessly) if it is not practical to connect any CT to the eddi or zappi.
- Page 34 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 or zappi (wired sensor) or harvi (wireless sensor).

Load Balancing / Current Limiting CTs can be also used to limit the current drawn by myenergi devices to avoid overloading circuits; this is sometimes referred to as load balancing. There are four different ways to limit current and they can be used alone or combined for more complex situations. - Page 38 The 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. Wire the CT to the nearest myenergi device or use a harvi unit if a wireless connection is needed.
