Written by Adrian Dorney | May 11, 2023 11:13:07 PM

In the ever-developing world of electric vehicle chargers, the Zappi car charger has established itself as one of the most reliable choices available to consumers in Ireland.

Manufactured by Myenergy, a UK-based designer and producer of renewable products, the Zappi charger is both unique and revolutionary. Furthermore, the Zappi possesses certain idiosyncrasies that make it an ideal option for individuals who wish to power their electric cars exclusively through renewable sources, such as solar power or wind turbines.

As always, the experts at Wattcharger are here to provide you, whether you are an existing or prospective EV owner, with a comprehensive and unbiased review of this state-of-the-art product, along with some lesser-known features that will enhance your overall experience.

 

Introducing the Zappi by MyEnergi

 

The Zappi charger made its debut in the UK market in 2017, followed by the release of the Zappi 2 for homeowners in the UK and Ireland in 2019. Today, thanks to Myenergi's proactive approach and utilization of powerful yet underutilized microchips, they are able to ship approximately 1,500 Zappi units every week from their manufacturing center in Grimsby, Lincolnshire.

Zappi users can choose between a white and black color scheme. These models have dimensions of 439 x 282 x 122mm and are constructed using Acrylonite Styrene Acrylate (ASA), a synthetic material known for its waterproof properties. Despite weighing 7.305kg, this compact charging point can easily fit into various setups, no matter how modest or exposed they may be.

One notable feature of Zappi chargers is the availability of two distinct power settings for consumers. The lower-powered option offers 7 kWh single-phase charging power, while the higher-powered option boasts an impressive 22 kWh triple-phase clip.

A useful way to estimate average charging times is to divide the battery storage capacity of a vehicle by the strength of the charger. For instance, an average EV with a battery capacity of 54 kWh would take approximately 8 hours to charge using the Zappi charger. However, with the 22 kWh Zappi unit, the same model can be fully charged in less than three hours.

Additionally, Zappi charge points are offered in two variations: with or without an attached charging cable. Tethered chargers come with a 6.5-meter cable, which typically incurs an additional cost. Homeowners seeking a more organized setup may choose the untethered model, which does not include the charging cable. For further insights into the differences between tethered and untethered models, we recommend referring to Wattcharger's comprehensive guide on the subject.

However, the true value of Zappi lies in its ability to utilize and monitor renewable energy usage. As the world's first solar-compatible electric car charger, Zappi is the ideal charging option for homeowners in Ireland who already have solar PV panels or other renewable energy sources installed.

Zappi offers an unprecedented level of discretion in energy usage through its three charging modes:

  • ECO mode: In this mode, the charge point sets a minimum charge rate of 1.4 kW. While energy derived from solar panels can surpass this threshold, grid energy ensures that the charge rate never falls below 1.4 kW.
  • ECO+ mode: This mode allows users to define their own "Min Green Level" to maximize renewable energy utilization. Homeowners can configure their Zappi to halt energy flow if solar power or wind generation drops below a specific point. This feature enables efficient tracking and optimization of renewable power within the Zappi infrastructure.
  • FAST mode: Utilizing two Triple-Phase plugs, FAST mode enables rapid vehicle charging in the traditional manner, ensuring that your vehicle receives the necessary power quickly and efficiently.

Zappi's charging modes are conveniently accessible and controllable through Myenergi's groundbreaking app. Apart from switching between modes and regulating energy load balancing, the user-friendly app includes timers for off-peak charging and provides real-time information on both historical and anticipated energy usage.

To measure and transmit energy flow information, the app relies on internal Current Transformers (CT Clamps). In addition to these features, Myenergi offers a 3-year warranty on all Zappi purchases, providing consumers with a future-proof framework and peace of mind.

 

Purchasing the Zappi

 

As we have observed, the Zappi charger offers different charge rates, which are reflected in their respective prices.

Tethered vs. Untethered Cable: An additional factor influencing the price of Zappi chargers is whether the model includes a charging cable. Zappi charge points are available in two variations: with or without an attached charging cable. Tethered chargers come equipped with a 6.5-meter cable, typically incurring higher costs. Homeowners seeking a tidier setup may opt for an untethered model, which does not include the cable.

Currently, Wattcharger offers untethered 7 kW Zappi chargers priced at €975, while tethered models are listed at €1,115 for the 22 kWh charge rate units. In contrast, tethered models are priced at €999 for the 7 kWh option or €1,180 for the 22 kWh option. Both models are available in stock and can be purchased directly from Wattcharger's website.

 

SEAI Electric Home Charger Grant

 

While the initial costs may appear prohibitive, it is important for Irish consumers to be aware of the Sustainable Energy Authority of Ireland's (SEAI) grant program designed to support homeowners in acquiring an EV charger.

Through the Electric Vehicle Home Charger Grant Scheme, the SEAI is committed to providing a grant of €300 to homeowners in Ireland for the purpose of purchasing and installing home charge points, including Zappi. To take advantage of this generous program, homeowners must engage an electrical contractor who is registered with Safe Electric Ireland.

Once you have selected a registered contractor, you are ready to proceed with the installation of your Zappi home charge point.

 

Zappi Charger Installation

 

Once you have purchased your Zappi, it is time to proceed with the installation of this innovative home charge point.

One notable advantage of the Zappi is that it can be installed without the need for earth rods. Earth rods are underground conductors used to redirect excess electricity by channeling currents into the ground. However, with the incorporation of built-in Residual Current Devices (RCDs), the Zappi can automatically interrupt the electricity flow in the event of an electrical fault.

To harness renewable energy from sources like solar PV panels or wind generation, it is necessary to place a CT clamp around the output cable originating from the green energy source. If the distance between the solar PV output cable and the Zappi charger exceeds 4 meters, it is recommended to consider using a Harvi device to ensure that your Zappi charger can efficiently access solar-generated electricity.

Harvi, a wireless energy-monitoring sensor also manufactured by Myenergi, utilizes a built-in sensor placed between the electricity meter and the unit to transmit information related to energy import and export. By connecting to the CT, Harvi can directly relay measurements and load-balancing data to the Zappi charger. It is an excellent choice for those who prefer a wire-free setup and do not require battery replacements. The Harvi device is currently available for approximately €55.

 

 Zappi Advantages

 

Using a Zappi charger is not only revolutionary but also incredibly convenient. Its sleek and compact dimensions ensure easy installation and compatibility with almost any property.

Furthermore, Zappi is designed to be compatible with a wide range of modern EV models available in the Irish market, including Tesla's entire fleet, up to their latest model, the Model X.

At a reasonable price, Zappi offers users unparalleled control and oversight through its brilliantly designed app. This app complements the future-proof nature of the Zappi EV charger, allowing homeowners to precisely manage their energy usage and its sources. Additional accessories like CT Clamps further enhance this process.

Zappi from Myenergi is the logical choice for Irish homeowners who already have renewable energy infrastructure and wish to utilize it to power their vehicles.

Even for those without access to renewable energy generation, the Zappi functions perfectly as a traditional EV charging unit by drawing electricity from the national grid. With remote access capabilities, users can monitor and control their unit from anywhere in the world, providing constant peace of mind.

Overall, Zappi is an exceptional unit that is built to withstand the test of time. Whether you are looking to connect your solar PV infrastructure, explore EV solutions, or purchase your own Zappi, feel free to contact Wattcharger using the tool below.
