If you’re an EV owner, you’ve almost certainly heard the name “Zappi.” As one of the UK’s best-selling home chargers, the MyEnergi Zappi has a reputation for being one of the smartest and most eco-friendly options on the market.

But what makes it so special? How does it work, and is it the right choice for your home? This simple guide will explain everything you need to know about the Zappi EV charger.

Who is MyEnergi?

Founded in 2016 by two friends, Lee Sutton and Jordan Brompton, MyEnergi was built on a simple question: “Can we make it easier to charge an electric vehicle using renewable energy?”

Based in Grimsby, the company has grown rapidly and is now a leading name in eco-smart technology, designing and manufacturing products that help you control how your home uses energy. Their mission is to help customers drive a sustainable future while saving money on their energy bills.

What is the Zappi EV Charger?

The Zappi is MyEnergi’s flagship product and one of the most popular EV chargers in the UK. While it works perfectly as a standard smart charger that takes power from the grid, its real magic lies in its ability to integrate with your home’s renewable energy sources. The MyEnergi Zappi has a reputation for being one of the smartest and most eco-friendly options on the market.

Put simply, the Zappi can detect when you’re generating more solar power than your house is using. It then intelligently diverts that surplus electricity directly into your car, meaning you can charge your EV for free.

The Zappi comes in a few different versions (tethered with a cable, or untethered), but they all share the same smart charging modes.

  • Eco: This is a mix of green energy and power from the national grid. The Zappi will always use your solar power first and will only top up from the grid if needed.
  • Eco+: This is the greenest mode. It will only charge your car when you have surplus green energy available, pausing the charge if you need to use that power elsewhere in your home.
  • Fast: This charges at full power, taking what it needs from your home’s green energy and the grid to charge your car as quickly as possible.

Does the Zappi Have Other Smart Features?

Yes, the Zappi is packed with features that give you more control and can save you money, even if you don’t have solar panels.

  • Smart Scheduling: You can schedule the Zappi to charge during specific off-peak hours when electricity is cheapest, such as on an Octopus Go tariff.
  • App Control: The MyEnergi app allows you to monitor your charging, set timers, and see exactly where your home’s energy is coming from in real-time.
  • PIN Code Protection: A simple PIN code lock prevents anyone from using your charger without your permission.

      What Are the Other MyEnergi Products? (The Zappi Ecosystem)

      The Zappi works perfectly on its own, but it’s also designed to be part of a wider “ecosystem” of smart energy devices.

      • Eddi Power Diverter: The Eddi does the same job as the Zappi, but for your hot water tank. It diverts surplus solar energy to your immersion heater, giving you free hot water.
      • Harvi Wireless Sensor: This clever little device monitors your home’s energy usage and communicates wirelessly with your Zappi and Eddi, making installation quicker and neater.
      • Libbi Home Battery: This is a modular home battery system that stores the surplus solar energy you generate during the day, allowing you to use it to charge your Zappi in the evening or as a backup during a power cut.

      An Engineer’s View

      “The Zappi is one of the most popular chargers we install, especially for customers with solar panels. Its Eco+ mode is a genuine game-changer for reducing running costs. While the unit itself is one of the larger ones on the market, its build quality is excellent, and the ability to wrap the cable around the unit is a practical touch. It’s without a doubt the best choice for anyone serious about charging their car with green energy.”

      Is the Zappi EV Charger Right for You?

      The MyEnergi Zappi has rightfully earned its reputation as a market-leading EV charger. It is incredibly well-made, packed with smart features, and designed and manufactured right here in the UK.

      For any homeowner with solar panels, the Zappi is almost certainly the best choice, offering a level of control and potential for free charging that is unmatched. Even without solar, its excellent smart scheduling and robust build quality make it a top contender.
