myenergi Brand Guidelines: The Lincolnshire Maker of the Solar-Matching zappi Charger

Two founders and one question.

myenergi writes its name in lower case, as one word, and it names its products the same way: zappi, eddi, harvi and libbi. The company was founded in 2016 by Lee Sutton and Jordan Brompton, as CleanTechnica reported in April 2023 and eeNews Europe in October 2023. Companies House lists myenergi Ltd as incorporated on 4 July 2016, with its business described as the manufacture of electronic components.

The company tells its own origin story plainly. It says the idea came from a conversation in Sutton’s living room and a simple question: why was there no product that let him charge his electric car from the solar panels on his house? It describes Sutton as an electrical engineer who had run renewable-energy technology companies before, and Brompton as the partner with the sustainability network and the marketing experience to build the brand.

The first products followed quickly. In a company news post dated January 2018, myenergi said it had launched the zappi charger and the eddi power diverter in September 2016, that the team then numbered seven people, and that it had secured investment from the businessmen Sir Terry Leahy, the former Tesco chief executive, and Bill Currie, founder of the William Currie Group, to increase production capacity. In that post Sutton said the aim was to develop affordable, easy-to-install products that help owners make the most of solar panels and wind turbines.

The business is a Humber company. Its registered office is at a business park in Stallingborough, near Grimsby in North East Lincolnshire, and the company says it moved there from a small countryside workshop into a purpose-built facility, where it is adding a production building of about 66,000 square feet so that its UK operations can sit on one site.

zappi, eddi, harvi and libbi.

The zappi is the product the company is built around. CleanTechnica reported in 2023 that myenergi presents it as the first smart charge point built to run on solar power, a claim that belongs to the company. As the magazine described it, the zappi works as an ordinary home charger from the grid and also offers modes named Eco, Eco+ and Fast, in which the charging power follows the surplus from a home solar or wind system and the use of power elsewhere in the house.

The other products extend the same idea around the home. The eddi diverts surplus self-generated electricity to heating, such as an immersion heater; the harvi is a wireless sensor that lets the devices be installed without running a cable to a current clamp; and the libbi is a modular home battery. An app links them, and the company’s website now also lists a zappi GLO and a three-phase eddi+.

Growth was quick. Startups placed myenergi at number 59 in its Startups 100 list in October 2021, when it had recently sold its 100,000th device and had subsidiaries in Germany, Ireland and the Netherlands. By April 2023, CleanTechnica reported, product sales had passed 500,000, the company employed more than 450 people at its Stallingborough headquarters, and it had subsidiaries in Germany, Australia, Ireland and the Benelux countries. The company’s own story today speaks of more than 3,000 approved zappi installers.

The company says it designs and manufactures its products, and its own story describes Stallingborough as where its production is based and growing. It names the Humber Freeport as the area where it started out.

Design and documentation.

Makers of electric-vehicle chargers sell a box that most people only notice when they need it. Their pictures therefore tend to put the hardware where it lives: a wallbox on a garage wall beside a parked car, a row of rapid chargers under a canopy at a motorway service area, a cable plugged into a car at dusk with the screen lit. The setting tells the buyer which kind of charging the company means, from overnight at home to a short stop on a long trip.

The second set of images is about the system rather than the plug. App screens show a charging session, a schedule or a fleet of chargers on a map, and diagrams show how power cabinets, posts and software connect. For makers that sell mainly to charging operators, depots and retailers, these pictures often matter more than the car, because the customer is buying a network that has to be installed, monitored and serviced.

Factories are the third theme. Many charger makers show their own production lines, with cabinets moving between stations, technicians testing power electronics and finished units waiting to be shipped, as a way of making engineering visible. Trade fairs play a similar part: events such as Power2Drive in Munich and the international EVS electric-vehicle symposium are where new chargers are unveiled, photographed and compared.

Many of these chargers spend their working lives in someone else’s colours. A rapid charger may carry the livery of the operator, the supermarket or the fuel company whose forecourt it stands on, so a maker’s identity often rests on form: the shape of the cabinet, the placement of screen and cable holders, and a name that may appear only in small type. Reading these brands means looking at the hardware as closely as at the logo.

Outside investors and a new chief executive.

The ownership has widened as the company grew. In 2023 myenergi took debt finance from HSBC and then, in October, an equity investment from Energy Impact Partners, the venture investor focused on the energy transition, as ESG Today and eeNews Europe reported. EIP’s Nazo Moosa joined the board alongside Sir Terry Leahy and Peter Richardson, a former chief operating officer of Dyson. Companies House lists a holding company, myenergi Group Ltd, incorporated in December 2022, at the same Stallingborough address.

The leadership changed at the start of 2025. BusinessCloud reported on 29 January 2025 that the company had appointed Andrew Clint, formerly of OpSec Security and De La Rue, as group chief executive, and that Lee Sutton had moved from chief executive to chief innovation officer. Fleet World reported the next day that Peter Richardson was executive chairman and that Jordan Brompton was stepping down from her executive role as chief marketing officer while staying on the board as a director and shareholder. The company’s own team page now lists Clint as chief executive and Sutton as co-founder and chief innovation officer.

The brand itself is consistent: one lower-case word for the company, short lower-case names ending in “i” for the products, and a vocabulary of “eco-smart” homes that the company uses across its website. It now runs country sites for the UK, Ireland, the Netherlands, Belgium, Luxembourg, Germany, Australia, New Zealand, Poland and France.

For a design guide, myenergi shows how a family of short, playful product names can make a technical range easy to remember. Compare Pod Point, another British home-charging brand, and Ohme, the London maker of smart home chargers. For this guide we use marsh green, estuary mist and rapeseed yellow with a rounded sans, an unofficial interpretation; no product or logo is reproduced.
