myenergi Zappi GLO vs Zaptec Go 2: solar today, V2G tomorrow?

Two different bets on the future of home charging

These chargers are priced £250 apart and sold to entirely different households. The myenergi Zappi GLO at £750 is a solar optimiser with a charging cable attached. The Zaptec Go 2 at £500 is a compact, V2G-ready socket betting on where the grid is heading next. Neither is trying to be the other.

The shortest version:

• myenergi Zappi GLO — the charger for people with solar panels. Eco+ mode runs the car from surplus generation. Pointless without a PV array on the roof.
• Zaptec Go 2 — the charger for people who believe vehicle-to-grid is coming. Certified V2G-ready, MID meter, free 4G, five-year warranty.

When the Zappi GLO earns its £750

If you have solar, this is the point of the product. Eco+ won't charge the car from the grid at all — it waits for surplus generation and diverts it, topping up only from what the panels would otherwise export for pennies. Eco mode blends grid and solar. The rest of the Zappi range exists to plug into the same ecosystem: eddi for hot water, libbi for battery storage. If you already own one, the GLO slots in.

If you don't have solar, the £750 buys you a sophisticated solar computer with nothing to compute. The tariff integration is manual rather than API-driven — the Ohme Home Pro at £535 does the smart-tariff job better for £215 less. The on-unit screen from the older Zappi 2.1 is gone; everything now happens in the app. Solar buyers looking at the wider field might want the Zappi GLO vs Hypervolt Home 3 Pro comparison too, since the Hypervolt also offers solar diversion.

What the Zaptec Go 2 is actually selling

At £500, the Zaptec Go 2 is priced like a mainstream charger but specified like a bet. The headline is V2G: it's the only AC home charger certified ready for vehicle-to-grid in the UK. That matters if — and only if — you think the technology will land inside the charger's working life. UK V2G is emerging; the vehicle support, the tariffs, the regulatory plumbing are all still being assembled.

Three things earn their keep today, regardless of whether V2G ever arrives for you. The MID-approved energy meter gives you legally certified readings — useful for expensing business miles or splitting shared-driveway costs. The built-in 4G works without a subscription, so if your Wi-Fi won't reach the driveway it still phones home. And the five-year warranty is two years longer than the Zappi's three. Against its nearest rivals, the Zaptec Go 2 vs Indra Smart PRO comparison is the sharper fight — both claim V2G readiness, at similar money.

The things neither does particularly well

Both charge a premium over the Easee One at £405 for features their buyers may not use. Both leave proper half-hourly tariff automation to someone else — on Octopus Agile, where rates shift every thirty minutes, the Ohme Home Pro does that job natively and neither of these chases it as well. On a fixed window like Octopus Go (00:30–05:30) or Octopus Intelligent Go (23:30–05:30), the gap closes because the schedule is set once and left alone.

The Zaptec is untethered only, so budget for a decent Type 2 cable. The Zappi offers both, with a 6.5-metre tethered option that's long.

The verdict

Buy the myenergi Zappi GLO if:

• You have solar panels now, or will within a year
• You already run — or plan to run — eddi or libbi
• You want a tethered cable and weatherproofing to IP65

Buy the Zaptec Go 2 if:

• You believe V2G will arrive within the next 5–7 years
• You need certified energy readings (business use, shared driveway)
• You want the longer warranty and free 4G without ongoing fees

If we had to put one on a wall today, for a household with no solar and no firm V2G plan, neither of these is the right answer — the Ohme Home Pro is. But between the two: the Zaptec Go 2, because £500 for a five-year warranty and a genuine MID meter is defensible on its own terms, with or without the V2G bet paying off. The Zappi only makes sense with panels overhead. Without them, £750 is a lot to spend on a feature you can't use.
