The Solar Specialist vs the Do-Everything Charger
These two sit at a similar price point — £599 for the Zappi GLO, £690 for the Hypervolt Home 3 Pro — but they're built around fundamentally different philosophies. The Zappi GLO exists to maximise your solar investment. The Hypervolt exists to be the charger you can't go wrong with. That distinction matters more than any spec on a data sheet.
In a nutshell:
- myenergi Zappi GLO: The undisputed solar champion, £91 cheaper, and part of a broader home energy ecosystem
- Hypervolt Home 3 Pro: Tougher build, more cable options, extendable warranty, and competent at everything without excelling at one thing
Is the Zappi GLO Worth It Without Solar Panels?
Bluntly, no. At £599, the Zappi GLO is one of the pricier chargers on the market, and its headline features — Eco mode, Eco+ mode, integration with myenergi's eddi and libbi products — all revolve around managing self-generated energy. Strip those away and you're paying a premium for a charger whose app still lags behind competitors and which has dropped the on-unit display that made the older Zappi 2.1 easy to glance at.
If you're on grid power only and want smart tariff scheduling, there are better options. Our smart charger guide covers those in detail.
But if you do have solar — or you're planning an installation — the Zappi GLO is in a league of its own. Eco+ mode will charge your car using nothing but surplus solar generation. Zero grid draw. Free miles. The Hypervolt's CT clamp solar integration is functional, but it's a bolt-on feature rather than the entire design ethos.

How Does the Hypervolt Home 3 Pro Justify Costing £91 More?
It's a fair question, and the answer comes down to build quality, flexibility, and peace of mind.
The Hypervolt carries an IP66 plus IK10 rating — that IK10 means it's impact-resistant, not just weatherproof. If your charger sits on an exposed driveway where it might catch a stray football or a reversing bumper, that's a meaningful advantage over the Zappi GLO's IP65. It's also the more compact unit at 270mm × 170mm × 110mm compared to the Zappi's 439mm × 282mm × 130mm. On a tight wall mounting spot, that difference is noticeable.
Then there's cable length. The Hypervolt offers 5m, 7.5m, or 10m options at purchase. The Zappi GLO gives you 6.5m. If your parking spot is further from your consumer unit, or you've got two cars in different positions, the Hypervolt's 10m cable could save you from needing a more complex installation.
And the warranty: both start at 3 years, but the Hypervolt can be extended to 5 years for £100. Over the life of a charger you'll likely own for a decade, that's cheap insurance. The Zappi GLO has no equivalent option.
The Ecosystem Question: Does myenergi's Wider Range Matter?
This is where the Zappi GLO pulls away for a specific type of buyer. myenergi makes the eddi (a hot water diverter) and libbi (a home battery). All three products talk to each other through a single app, creating a unified home energy management system. Surplus solar goes to your car first, then your hot water tank, then your battery — or whatever priority order you set.
The Hypervolt doesn't have anything like this. It's a standalone charger. A very good standalone charger, but if you're building out a solar-plus-battery home, the myenergi ecosystem is a compelling reason to start with the Zappi GLO.
That said, the Zappi GLO's reliance on Wi-Fi (no 4G fallback) means your home broadband needs to reach wherever you mount the unit. The Hypervolt has the same limitation, so neither wins here — but it's worth factoring into your installation planning.
Which Should You Buy?
Buy the myenergi Zappi GLO if:
- You have solar panels or are installing them soon
- You want to build a whole-home energy system with eddi and libbi
- You prefer spending less upfront (£599 vs £690)
- RFID access for up to 126 users matters — useful for shared driveways
Buy the Hypervolt Home 3 Pro if:
- You don't have solar and want a capable all-rounder
- Build quality and impact resistance are priorities (IP66 + IK10)
- You need a longer cable — up to 10m vs the Zappi's 6.5m
- You want the option to extend your warranty to 5 years
For most Tesla owners with solar panels, the Zappi GLO is the right call — it's cheaper and its solar features are unmatched. For everyone else, the Hypervolt Home 3 Pro earns its price through sheer reliability and versatility. Neither is a bad choice, but buying the Zappi without solar is like buying a 4×4 and never leaving the motorway.
