If you have solar panels, buy this. Eco+ is the reason — free charging from the roof, no moral arithmetic required. If you don't have solar, don't: the £750 buys you a more sophisticated solar computer than anyone without solar needs. The Ohme Home Pro for smart tariffs, the Tesla Wall Connector for everything else.

Figures are estimates. Your actual saving depends on how much charging you do in the off-peak window versus during the day, and on your provider's standing charge. Read the individual tariff reviews for the full picture.

The charger you buy because you have solar panels. In Eco+ mode, the Zappi runs the car entirely on surplus solar — whatever your panels produce above household load goes to the battery, and nothing else does. Free miles while the sun's out. Eco mode softens the rule, topping up from the grid when solar dips. Fast mode ignores solar altogether and pulls full power like any other charger. No other unit here handles surplus solar with this much control.

The rest of the story is the myenergi ecosystem. Pair the Zappi with an eddi to divert spare solar into the hot-water tank, or a libbi battery to store daytime solar for overnight car charging. At £750 it's one of the pricier chargers in this selection; without solar, that premium buys nothing the Tesla Wall Connector or Ohme Home Pro don't already deliver for less.

Best for: Solar households. The bigger the array, the better the fit. No solar? The Tesla or Ohme is probably your charger.

Installation

Larger than the Ohme or Tesla at 5.4 kg, 439 × 282 × 130 mm, but straightforward on a dedicated 32A circuit. For Eco and Eco+ to work, the installer fits a myenergi CT clamp on the meter tails — it reads your home's import and export in real time. Accredited installers include it as standard; budget for it if your electrician is new to myenergi. Tethered 6.5-metre cable, or an untethered version if you'd rather bring your own. No built-in RCD or SPD; both get added at the consumer unit. IP65 — fully weatherproof. Full walkthrough in our install guide.

Tariff compatibility

Scheduling happens in the myenergi app; compatible with Octopus Intelligent Go, Octopus Go, and other two-rate tariffs. Set the window, and the charger draws only during it. It doesn't automate half-hourly pricing on Octopus Agile the way the Ohme Home Pro does — for that, you pay the Ohme premium and give up the solar logic. The right setup for most Zappi owners: Eco+ during daylight (free surplus solar), a scheduled off-peak slot overnight (cheap grid). More on combining the two in our solar + EV charging guide.

Price

Element	Cost
Unit	£750
Typical installation	£400–£600
Installed, total	£1,150–£1,350

Eligible for the £500 OZEV grant if you're a renter or flat owner. A 4kW south-facing array in England generates enough surplus for roughly 8,000–10,000 miles of Tesla charging a year. At ~24p/kWh standard rate, that's £500–£600 of electricity you don't buy. The Zappi's premium over a basic charger typically pays itself back inside the first year.

Against the field

Against the Tesla Wall Connector: wins on solar, overkill without it. Against the Hypervolt Home 3 Pro: more sophisticated solar control; less polished on everything else. Against the Ohme Home Pro: better for solar, weaker on tariff automation. Head-to-heads: vs Hypervolt, vs GivEnergy, vs EO Mini Pro 3. Full pattern in our solar chargers guide.
