myenergi Zappi GLO vs Zaptec Go 2: Solar Pioneer vs V2G Trailblazer

Today's Best vs Tomorrow's Promise: Two Chargers With Very Different Bets

The myenergi Zappi GLO and the Zaptec Go 2 are both premium home EV chargers, but they're placing their chips on fundamentally different technologies. The Zappi GLO is built around solar diversion — a technology that's mature, proven, and saving UK homeowners real money right now. The Zaptec Go 2, meanwhile, is the UK's first V2G-ready AC home charger, betting that vehicle-to-grid technology will transform how we use our EVs in the years ahead.

If you're weighing these two up, you're likely someone who thinks beyond simply plugging in and charging. You want your charger to be part of a bigger energy picture — whether that's harvesting free solar electricity today or selling power back to the grid tomorrow. Both chargers sit in a similar price bracket and both support smart tariffs, but the way they earn their keep couldn't be more different.

In a nutshell:

• myenergi Zappi GLO (£779): The undisputed king of solar diversion, with three charging modes that let you charge your EV entirely from surplus solar power for free.
• Zaptec Go 2 (£707): A future-proofed charger with V2G readiness, built-in 4G, and a MID-approved energy meter — ready for a grid that doesn't quite exist yet.

Spec Comparison

Solar Diversion: The Zappi GLO's Killer Feature

If you have solar panels on your roof, this comparison is essentially over before it begins. The Zappi GLO's three charging modes — Fast, Eco, and Eco+ — give you unmatched control over how your EV uses solar energy. In Eco+ mode, the charger draws power exclusively from surplus solar generation, meaning you're charging your car for absolutely nothing. Eco mode blends solar surplus with grid power to maintain a minimum charge rate, which is ideal for days when the sun keeps ducking behind clouds.

The Zaptec Go 2 does offer some solar integration through its ability to auto-switch between single and three-phase charging for optimal solar use, but it doesn't have dedicated solar diversion modes. It's a useful feature, but it's not in the same league as the Zappi's purpose-built system. If you're generating 3kW of surplus solar, the Zappi will use exactly that to charge your car. The Zaptec simply doesn't offer that level of granularity.

For context, a typical UK solar PV system (4kWp) might generate around 3,400 kWh per year. If you divert even a third of that surplus into your EV via the Zappi GLO's Eco+ mode, you could save roughly £150–£200 annually compared to charging at standard grid rates — and considerably more if energy prices rise again. The Zappi also integrates with myenergi's wider ecosystem, including the eddi hot water diverter and libbi battery storage, letting you build a comprehensive home energy management system over time, as noted by electriccarguide.co.uk.

Connectivity and Future-Proofing

Here's where the Zaptec Go 2 fights back convincingly. It comes with subscription-free 4G connectivity built in, meaning it doesn't rely on your home Wi-Fi reaching the driveway. Anyone who's struggled with a weak Wi-Fi signal at their charging point will appreciate this enormously. The Zappi GLO, by contrast, depends entirely on Wi-Fi and Bluetooth — if your router is at the front of the house and your charger is at the back, you may need a Wi-Fi extender.

The Zaptec Go 2 is also the UK's first V2G-ready AC home charger. Vehicle-to-grid technology allows your EV to feed stored energy back to the grid during peak demand, potentially earning you money. It's a genuinely exciting prospect, though it's worth being honest: V2G is still in its infancy in the UK, with limited vehicle compatibility and few active tariff schemes supporting it. You're paying for a feature that may take several years to become mainstream.

The Go 2 also includes a MID-approved energy meter and OCPP 1.6J compliance, making it compatible with third-party energy management systems. These are features that matter more in commercial or shared-use settings, but they add flexibility that the Zappi GLO doesn't match. As autochain.co.uk highlights, both chargers support smart tariff integration with providers like Octopus Energy, though the Zappi GLO's direct Intelligent Octopus Go compatibility is well documented.

Build Quality and Design

These two chargers couldn't look more different. The Zaptec Go 2 is remarkably compact at just 240 × 180 × 106mm and weighing only 3.2 kg — it's roughly the size of a hardback book. Its Scandinavian design is minimal and unobtrusive. The Zappi GLO is noticeably larger at 439 × 282 × 130mm and 5.4 kg, though myenergi has slimmed it down and removed the on-unit screen from the older Zappi 2.1, going for a cleaner look managed entirely through the app.

The Zappi GLO wins on weather protection with an IP65 rating (fully dust-tight and protected against water jets), compared to the Zaptec's IP54 (protected against splashing water). Both are perfectly adequate for UK weather, but if your charger is fully exposed to driving rain with no shelter, the Zappi's higher rating offers extra peace of mind. The Zappi GLO also supports RFID access for up to 126 users, as confirmed by myenergi.com, which is handy for shared driveways or small workplaces.

One practical difference: the Zappi GLO is available as both tethered (with a 6.5m cable) and untethered, while the Zaptec Go 2 is untethered only. If you prefer the convenience of a permanently attached cable — no fumbling in the boot — the Zappi has the edge. The Zaptec's untethered design does mean a tidier wall-mounted unit and the flexibility to use different cables, but you'll need to supply your own Type 2 cable (typically £80–£150 extra).

Price and Value

The Zaptec Go 2 is £72 cheaper at the unit level, and that gap holds through to the total installed price. However, the Zaptec is untethered only, so factor in £80–£150 for a decent Type 2 cable, which narrows or eliminates the price difference. The Zaptec does offer a significantly longer 5-year warranty versus the Zappi's 3 years, which adds genuine long-term value.

The real value question comes down to what you'll actually use. If you have solar panels, the Zappi GLO could pay back its premium many times over through free solar charging. If you don't have solar, you're paying £779 for features you won't use — and the Zaptec's V2G readiness, 4G connectivity, and longer warranty become more compelling at the lower price.

Who Should Buy Which?

Buy the myenergi Zappi GLO if:

• You have solar panels and want to charge your EV from surplus solar for free
• You want a tethered charger with a 6.5m cable ready to go
• You're building a myenergi ecosystem with eddi or libbi
• You need RFID access for multiple users on a shared driveway
• You want the highest weatherproofing rating (IP65) for an exposed installation

Buy the Zaptec Go 2 if:

• You want a V2G-ready charger that's future-proofed for vehicle-to-grid technology
• Your Wi-Fi doesn't reach your charging point — the built-in 4G solves this instantly
• You prefer a compact, unobtrusive wall unit with a clean untethered design
• A 5-year warranty matters to you
• You need OCPP compliance or a MID-approved meter for energy tracking

Our recommendation: For most UK buyers today, the myenergi Zappi GLO is the smarter purchase — but only if you have solar panels. Its solar diversion technology is proven, mature, and delivers real savings right now. If you don't have solar, the Zaptec Go 2's combination of built-in 4G, longer warranty, and V2G readiness makes it the more interesting proposition at a lower price point. The V2G feature is a genuine gamble on the future, but if it pays off, early adopters will look very clever indeed.
