Page 4: Introduction
Introduction zappi Thank you for choosing . Of course, we think you have made an excellent choice and are sure you will be very happy with myenergi the features, benefits and quality of this product. zappi These instructions will help you to familiarise yourself with the , by reading the instructions, you will be sure to get the maximum benefit from this 'eco-smart' device. -
Page 5: Overview
Introduction 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 SAE J1772, EN62196 and EN61851 plug-in electric vehicle standards. zappi works like any regular charging point but has special eco charging modes which will benefit homeowners with grid-tied microgeneration systems, like wind or solar generation. -

Operation Charge Complete The EV is fully charged. The charge energy used during the last charge is displayed at the bottom right (20.0kWh in this case) and the 'green contribution' is also shown (40% in this example). Restart... Zappi is doing a restart sequence. This may happen with some EVs that need to be 'woken-up' to start charging after a pausing charge. -
Page 11: Charging Modes
Operation Charging Modes zappi has three different charging modes which can be selected simply by pressing the button when the main screen is showing. The charge mode can be changed before or during a charge. zappi's Regardless of the charge mode used, all of the surplus electricity is used but 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 zappi maximum (just like FAST mode), until a set amount of energy has been stored in the EV's battery. After which, will revert back to ECO or ECO+ mode. -
Page 13: Smart Boost
Operation Smart Boost The Smart Boost function will charge the EV with a minimum kWh figure by a set time. Smart Boost is available only in ECO and ECO+ modes. The Smart Boost function does not bring the battery to a certain state of charge. The target kWh is only the energy added during the charging session. -
Page 14: Boost Timer
Operation Boost Timer zappi When using ECO or ECO+ charge modes, 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. This means that power may be drawn from the mains grid supply during boost times. -
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 or only when unplugged, it can also be set to be always active. -

Unscrew the 12 M4 screws now exposed and lift off the enclosure cover. Offer the unit up to the wall and mark the holes for drilling. If fixing to a timber stud wall, you can use the two central vertically aligned fixing points to screw the enclosure directly into the timber.

Installation Advanced Installation Options Load Balancing / Current Limiting myenergi CTs can be also used to the limit current drawn by 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 30 This is possible by installing an extra CT to monitor the diverter. The CT should be clipped around the Live cable of the supply feeding the diverter. The arrow on the CT should be pointing away myenergi from the diverter. Wire the CT to the nearest device Configure the CT Type as Storage Only.

Page 31: Esense Input (Economy Tariff)
Installation eSense Input (economy tariff) zappi has an input which can be used to sense the availability of economy tariff electricity, this can be used to automatically boost the charge when in ECO or ECO+ charging modes. The eSENSE input is electrically isolated and effectively draws no current so the cable size is not important. An AC voltage between 100V and 260V across the L and N terminals of the eSENSE input cause the economy tariff symbol to be shown on the main screen. -
