myenergi Zappi GLO vs EVEC VEC03: The £381 solar question

£369 or £750 — what the gap actually buys

These two chargers sit at opposite ends of the UK home-charging price range, and the distance between them is almost entirely explained by one word: solar.

The EVEC VEC03 costs £369 — the cheapest OZEV-approved smart charger you can buy. The myenergi Zappi GLO costs £750, making it £381 more expensive. That £381 buys a sophisticated solar diversion system. If you don't have panels on your roof, it buys you nothing useful.

• EVEC VEC03 — the minimum viable smart charger. £369, built-in RCD, OCPP 1.6J, gets the job done.
• myenergi Zappi GLO — a solar computer that happens to charge cars. £750, three diversion modes, ecosystem hooks into eddi and libbi.

When the Zappi GLO earns its premium

The Zappi GLO's Eco+ mode runs your car entirely from surplus solar generation. On a sunny afternoon with a 4kW array producing more than the house needs, the excess goes into the car instead of being exported at 4–5p/kWh. Charge from the roof instead of the grid at 24p/kWh and the arithmetic is plain — every kWh diverted saves roughly 20p. At 2,500 kWh per year of EV charging (a reasonable UK average), even partial solar coverage starts clawing back the £381 gap within a year or two.

The Zappi GLO also plugs into myenergi's broader ecosystem. Pair it with an eddi for hot-water diversion or a libbi battery, and the whole house becomes a single energy-management system. For homes already invested in myenergi hardware, or planning to be, the Zappi GLO is the obvious charger. If you're weighing it against other solar-capable options, the GivEnergy EV Charger at £478 offers a different route — particularly if you're already in GivEnergy's battery ecosystem.

Without panels, none of this applies. The Zappi GLO becomes a £750 7kW charger with no meaningful advantage over units costing half as much.

The EVEC VEC03's real selling point — and its real weakness

The VEC03's strongest card is not the £369 price tag itself but what sits inside the box: a Type A RCD with 6 mA DC leakage detection and PEN fault protection. Most chargers need these fitted in the consumer unit at install, adding roughly £100 to the electrician's bill. The VEC03 arrives with them built in, so the total outlay — unit plus install — undercuts almost everything else on the market.

For grant-eligible buyers (renters and flat owners), the £500 OZEV grant covers the £369 unit outright and contributes to install costs too. That makes the VEC03 the cheapest possible route to a compliant home charger.

The weakness is software. The EVEC app has a recurring reputation for flaky scheduled charging over Wi-Fi. There is no direct API integration with any UK smart tariff — no Octopus Intelligent Go compatibility, no OVO Charge Anytime hook. OCPP 1.6J support means you can connect to Monta or another back-end for more control, but that is an extra layer of setup most buyers would rather not think about. The 5-metre cable is also the shortest tethered option in the catalogue — fine if the charger sits right beside the parking spot, a nuisance if it doesn't.

For buyers who want a cheap charger *and* reliable smart-tariff integration, the Ohme Home Pro at £535 is the more complete product. It costs £166 more than the VEC03, but its direct tariff API — particularly on Octopus Agile — pays that back over a year or two of variable-rate charging. The Easee One at £405 is another step up from the VEC03: £36 more, with a lifetime 4G SIM and a more settled software platform.

Neither charger is a smart-tariff specialist

This matters because most buyers end up on an EV tariff. On a simple two-rate plan like Octopus Go — 8.5p/kWh between 00:30 and 05:30 — both chargers can be manually scheduled to charge in that window. The VEC03's app should handle it, Wi-Fi reliability permitting. The Zappi GLO's app will do the same, though myenergi's tariff integration is manual rather than API-driven.

On anything more dynamic — Agile's half-hourly pricing, Intelligent Go's slot optimisation — neither charger keeps up. If smart-tariff hunting is a priority, the Ohme Home Pro vs Zappi GLO comparison is a more useful pairing to read.

The verdict

Buy the myenergi Zappi GLO if:

• You have solar panels and want to charge from surplus generation
• You're already in, or planning to join, the myenergi ecosystem (eddi, libbi)
• You need RFID access for a shared driveway — up to 126 users

Buy the EVEC VEC03 if:

• You have no solar panels and want the lowest total cost to a working smart charger
• You're a renter or flat owner eligible for the £500 OZEV grant
• You're on a flat-rate or simple off-peak tariff and don't need tariff API integration

The decision is binary. Panels on the roof — the Zappi GLO. No panels — the VEC03, or one of the stronger mid-range options if you can stretch the budget. Spending £750 on a solar diverter when there's nothing to divert is a poor use of £381.
