myenergi Zappi GLO vs Zaptec Go 2: A Feature You Use Now vs One You Might Use Later
These are two of the pricier home chargers on the UK market, and neither apologises for it. The myenergi Zappi GLO at £599 is built around solar diversion — a feature that saves real money right now if you have panels on your roof. The Zaptec Go 2 at £707 bets on V2G, a technology that could be transformative but isn't widely available yet.
In a nutshell:
- myenergi Zappi GLO: The best solar EV charger you can buy, with a proven ecosystem behind it
- Zaptec Go 2: A compact, future-proofed charger with built-in 4G and V2G readiness
The core question here isn't really about specs. It's about whether you want to save money today or hedge for tomorrow.
Is the Zappi GLO Worth £599 Without Solar Panels?
Honestly? No. Strip away the solar diversion and the myenergi ecosystem integration, and you're left with a £599 charger that does roughly what a £400 charger does. The app has improved but still trails behind competitors, there's no 4G fallback, and the 3-year warranty is merely average.
But with solar panels, the calculus flips entirely. Eco+ mode charges your car exclusively from surplus solar — that's genuinely free fuel. Eco mode blends solar and grid power so you're never waiting around on a cloudy day. No other charger handles this as well. And if you later add a myenergi eddi or libbi, you've got whole-home energy management that actually works as a system rather than a collection of separate apps.

Does V2G Make the Zaptec Go 2 Worth £707?
Not yet — and that's the uncomfortable truth. The Zaptec Go 2 is the UK's first V2G-ready AC home charger, which sounds impressive until you realise that V2G infrastructure, tariff structures, and compatible vehicles are all still in their infancy. You're paying a premium for a capability that might not deliver real-world value for another two to three years, possibly longer.
What does justify some of that price is the rest of the package. The subscription-free 4G is excellent — no reliance on your home Wi-Fi, no ongoing costs. The MID-approved energy meter means precise billing data, which matters if you're claiming business mileage or splitting costs with a partner. And the 5-year warranty gives you two extra years of cover versus the Zappi GLO. At just 3.2 kg and 240mm × 180mm × 106mm, it's also remarkably compact — almost half the weight of the Zappi GLO.
The weakness is that it's untethered only. You'll need your own Type 2 cable, which adds £50–150 to the real cost. The Zappi GLO includes a 6.5-metre tethered cable and also offers an untethered option, giving you more flexibility at a lower starting price.
Connectivity and Smart Tariffs: A Split Decision
Both chargers support scheduled charging and smart tariff integration, but they approach connectivity differently. The Zaptec Go 2's built-in 4G means it works reliably even if your garage is in a Wi-Fi dead zone — a real advantage for detached garages or outbuildings. The Zappi GLO relies on Wi-Fi and Bluetooth only, which can be frustrating if your router doesn't reach your driveway.
For smart tariff optimisation specifically, the Zappi GLO is compatible with Intelligent Octopus Go, which is one of the cheapest overnight rates available. The Zaptec Go 2's OCPP 1.6J compliance means it plays nicely with third-party energy management systems, but its own app is fairly basic. Neither charger matches the Ohme Home Pro for pure smart tariff smarts, but they both get the job done.
It's also worth flagging the IP ratings: the Zappi GLO's IP65 is a step above the Zaptec Go 2's IP54. If your charger will be fully exposed to the elements with no shelter, the Zappi GLO offers better weather protection.
Which Should You Buy?
Buy the myenergi Zappi GLO if:
- You have solar panels or plan to install them — nothing else comes close for solar diversion
- You want a tethered charger with cable included
- You're already in or planning to build a myenergi ecosystem
- Full outdoor exposure demands IP65 protection
Buy the Zaptec Go 2 if:
- V2G is part of your long-term energy strategy and you want to be ready early
- Your charger location has poor Wi-Fi and you need built-in 4G
- A 5-year warranty matters to you on a premium purchase
- You prefer an untethered setup and already own a Type 2 cable
For most Tesla owners reading this today, the Zappi GLO is the smarter purchase — but only if you have solar panels. Its core feature works right now and saves real money every sunny day. If you don't have solar and V2G doesn't excite you, both of these chargers are overpriced for your needs. Look at the Ohme Home Pro or check our best smart EV charger guide instead.
