myenergi Zappi GLO vs GivEnergy EV Charger: solar roof or home battery?

Two specialists, not two all-rounders

This is a pairing most buyers will get wrong if they treat it as a general charger comparison. The myenergi Zappi GLO at £750 and the GivEnergy EV Charger at £478 are both tools built for a specific home energy setup. Strip away the setup and what you're left with, in both cases, is a charger that's either overpriced or undersmart against the broader market.

The £272 gap isn't about features. It's about which rooftop — or which cupboard — you already own.

• Zappi GLO — the solar charger. Three diversion modes, 22kW three-phase option, myenergi ecosystem. £750, and worth it only if panels feed it.
• GivEnergy EV Charger — the battery charger. Pulls stored energy from a home battery into the car. £478, and worth it only if a battery feeds it.

When the Zappi GLO earns its £750

Eco+ is the argument. The Zappi GLO throttles charging to match live solar surplus — when a cloud passes, it pauses; when the sun returns, it resumes. The car runs on electricity you'd otherwise export for pennies. Over a year, for a household with a decent array, that's where the premium goes back into your pocket.

The wider myenergi ecosystem is the other reason. If you already have an eddi diverting surplus to the immersion heater, or a libbi storing it in a home battery, the Zappi talks to them natively. Priorities can be set across devices. That's a genuine integration story, not a marketing one.

Without panels, though, the picture collapses. The app does not do live tariff chasing — tariff integration is schedule-based, which the Ohme Home Pro does better for £535. The old on-unit screen is gone. You'd be paying £750 for a solar computer with nothing to compute. Buyers on that path should read the Ohme vs Zappi GLO comparison or skip straight to the best EV charger for solar guide.

When the GivEnergy EV Charger earns its £478

Battery-to-EV is rarer than it sounds. Most "solar" chargers can only use live generation — if the sun isn't shining, the diversion is off. The GivEnergy EV Charger pulls from a home battery, which means you can store electricity at Octopus Go's 8.5p/kWh off-peak rate or Octopus Intelligent Go's 7p/kWh, then feed the car at your convenience from those stored kWh.

It isn't locked to GivEnergy's own battery. Compatible third-party units work too. For a household already running a battery, that's a combination no other charger in this selection offers cleanly.

Without a battery, the picture again collapses. The GivEnergy is 7kW single-phase only, the app is basic next to Hypervolt or Ohme, and at £478 the Easee One undercuts it at £405 while the Tesla Wall Connector matches its price with a 7.3-metre cable and Tesla-native scheduling. It becomes an ordinary charger with a feature you aren't using.

What neither of these does well

Both are weak on live tariff chasing. Schedule-based charging is fine on Octopus Go or E.ON Next Drive, where the off-peak window is fixed. On Octopus Agile, where rates move every half hour, neither charger has the API integration to follow them. If your setup is "smart tariff, no solar, no battery", you're in the wrong comparison — the Ohme Home Pro is the charger that does that job.

Neither has 4G backup. Both rely on Wi-Fi, which in a detached garage at the end of the driveway can mean reliability issues the Cord Zero handles better.

The verdict

Buy the myenergi Zappi GLO if:

• You have solar panels and want the car to charge from surplus generation
• You already own or plan to own myenergi eddi or libbi devices
• You have a three-phase supply and want the 22kW option

Buy the GivEnergy EV Charger if:

• You have a home battery (GivEnergy or compatible third-party)
• You want to shift stored overnight-cheap electricity into the car
• Single-phase 7kW is enough for your driveway

If a gun were to our heads and we had to pick one for a wall without knowing the house, the GivEnergy's £478 is harder to waste than the Zappi's £750 — the penalty for buying the wrong specialist is smaller. But the right answer is: audit your roof and your cupboard first. If there's nothing solar and nothing stored, close both tabs and open the Ohme Home Pro or the Tesla Wall Connector instead.
