The Smart Way to Charge Your Electric Vehicle

Owning an electric vehicle is one of the most significant steps you can take to reduce your carbon footprint and cut your transport costs. But to get the most from your EV, you need a dedicated home charging point that is fast, reliable, and intelligent enough to work with your energy system. That is where the Zappi charger from myenergi comes in, and why D&R Energy recommends it as the best EV charging solution for homes with solar panels across Bristol and Somerset.

The average UK household spends over £1,200 per year on petrol or diesel. Switching to an electric vehicle can reduce that cost to £300-£500 per year when charging from the grid, but when you combine an EV with solar panels and a Zappi charger, your driving fuel costs can drop to virtually nothing. The Zappi is the only widely available EV charger in the UK that is specifically designed to integrate with domestic solar PV systems and battery storage, allowing you to charge your car using surplus energy that would otherwise be exported to the grid.

Why the Zappi is the Best Solar EV Charger

myenergi is a British company that has revolutionised home energy management. Their Zappi charger is the UK's most popular solar-compatible EV charger, and for good reason. It is the charger that D&R Energy installs and trusts across every property in our service area, from modern family homes in Portishead to Victorian terraces in Bristol and bungalows in Weston-super-Mare.

ECO Mode: Solar-Only Charging

The Zappi's ECO mode only draws power when your solar panels are generating surplus electricity. This means your EV charges entirely from free solar energy. On a sunny spring or summer day, a 4.5kW solar system can deliver 20-30 miles of free driving range while you are at work or at home.

ECO+ Mode: Maximum Solar Priority

ECO+ is the Zappi's most intelligent mode. It waits until there is a minimum surplus of 1.4kW from your solar panels before starting to charge, ensuring your home appliances are powered first. Once the threshold is met, it dynamically adjusts the charging rate to match available solar output.

FAST Mode: Full Speed Charging

When you need your EV charged quickly regardless of solar availability, FAST mode draws the maximum power from the grid. This is ideal for unexpected journeys or when you need a rapid top-up. The Zappi delivers up to 7kW of charging power, adding approximately 30 miles of range per hour.

Smart Tariff Integration

The Zappi integrates with smart energy tariffs such as Octopus Go and Intelligent Octopus, allowing you to schedule charging during the cheapest overnight rate periods. Combined with solar charging during the day and cheap grid charging at night, you can eliminate expensive peak-rate electricity entirely.

How Solar Divert Works (ECO+ Mode)

A CT clamp reads your real-time solar generation and home consumption. ECO+ mode diverts only surplus solar to your EV — completely free charging at whatever rate your panels are producing (1.4kW minimum). There is no grid draw, no electricity cost.

OZEV Grant (April 2026): The government EV chargepoint grant is no longer available for standard homeowners. It remains available for renters, flat owners with private parking, and some communal parking situations (up to £500 or 75%). D&R Energy can advise on current eligibility.

The Complete Home Energy System

The most powerful combination for energy independence is a solar PV system, battery storage, and a Zappi EV charger working together. During the day, your solar panels generate electricity that powers your home, charges your battery, and tops up your EV. In the evening, your battery provides stored solar energy for your home. If you have an overnight smart tariff, your Zappi can schedule grid charging at the cheapest possible rate while your battery recharges simultaneously.

D&R Energy installs complete integrated systems using premium Jinko Solar or Exiom panels, GivEnergy or Tesla Powerwall battery storage, and the myenergi Zappi EV charger. Our team designs every system to work as a unified whole, with all components communicating intelligently to maximise your self-consumption and minimise your bills. The GivEnergy app, Tesla app, and myenergi app give you full visibility and control over every kilowatt-hour from your smartphone.

For a typical family in Bristol or North Somerset with a 4.5kW solar system, a 5.12kWh battery, and a Zappi charger, the combined savings on household electricity and transport fuel can exceed £2,000 per year. Over the 25+ year lifespan of your solar system, that represents savings of more than £50,000 at current energy prices.

What to Expect from Your Zappi Installation

A Zappi EV charger installation from D&R Energy typically takes half a day and includes everything you need to start charging. Our NAPIT-registered electricians will survey the best location for your charger, typically near your driveway or garage, and install it with a dedicated circuit from your consumer unit. If you already have solar panels, we configure the Zappi's CT clamp to monitor your solar generation in real-time, enabling the ECO and ECO+ charging modes.

If you are adding a Zappi alongside a new solar PV and battery installation, we integrate all components in a single visit, saving time and cost. Our team sets up the myenergi app on your phone, walks you through every charging mode, and ensures you are confident operating the system before we leave. The Zappi comes with a three-year manufacturer warranty, and D&R Energy provides aftercare support for the life of the product.

A Zappi EV charger typically costs £800-£1,500 fully installed, depending on the electrical work required at your property. When installed alongside a solar PV and battery package from D&R Energy, we offer competitive combined pricing that makes the whole system even more cost-effective.

EV Charger FAQs

Yes — and this is one of the smartest energy combinations available. A Zappi EV charger from myenergi can be set to charge only when surplus solar electricity is available, meaning you charge your car for free. Combined with battery storage, you can store solar during the day and charge overnight from stored energy.

We install the Zappi charger from myenergi — the UK's leading smart EV charger designed specifically for solar integration. The Zappi can automatically detect and use surplus solar electricity to charge your EV, maximising your free energy usage.

A Zappi EV charger typically costs £800-£1,500 fully installed, depending on the electrical work required. If you are adding it alongside a solar PV and battery installation, D&R Energy can offer competitive package pricing.

No — you can install a Zappi EV charger without solar panels and still benefit from its smart features, including scheduled off-peak charging using cheap overnight tariff electricity. However, pairing the Zappi with solar panels and a battery gives you the maximum benefit: free solar-powered car charging during the day and cheap grid charging overnight.

The Zappi is a 7.4kW single-phase Type 2 charger, which can add approximately 30 miles of range per hour of charging. In pure solar mode, charging speed depends on how much surplus solar electricity is available — typically 1.4kW to 7kW depending on sunlight. In fast charge mode, it draws the full 7.4kW from the grid for maximum speed.

The OZEV EV chargepoint grant for domestic properties ended in April 2022 for most homeowners. However, grants are still available for people living in flats and for those installing chargers at rental properties. D&R Energy can advise you on current eligibility during your initial consultation.

Yes — the Zappi charger uses a standard Type 2 connector and is compatible with all modern electric vehicles sold in the UK, including Tesla, BMW, Volkswagen, Nissan, Kia, Hyundai, Ford, and every other EV brand. Tesla vehicles require the Type 2 adapter supplied with the car.
