myenergi Zappi GLO vs Hypervolt Home 3 Pro

The £26 between a solar specialist and a charger that does everything

The myenergi Zappi GLO costs £599. The Hypervolt Home 3 Pro costs £625. A £26 gap — barely a rounding error once installation is factored in. Yet these are fundamentally different propositions.

• Zappi GLO — a solar-diverting charger first, a smart charger second. If you have panels on the roof, this is the one.
• Hypervolt Home 3 Pro — competent at everything, best at nothing. The charger you buy when you don't want to think about it again.

Why the Zappi GLO only makes sense with solar

The Zappi GLO's entire personality is its Eco+ mode: it charges the car exclusively from surplus solar generation, drawing nothing from the grid. Eco mode blends grid and solar. Fast mode ignores the panels entirely. These three modes, toggled in the myenergi app, are the reason the charger exists — and the reason it costs £599 instead of £450.

Strip the solar away and the Zappi GLO becomes an expensive 7kW charger with Wi-Fi and an RFID reader. It handles smart tariff scheduling, but not as nimbly as the Ohme Home Pro, which at £539 is £60 cheaper and negotiates half-hourly slots on Octopus Intelligent Go that the Zappi cannot access. If your home has no panels — and no plans for them — the Zappi GLO is the wrong charger. Full stop.

With panels, the arithmetic reverses. The Hypervolt Home 3 Pro includes a CT clamp for solar integration, but its diversion logic is basic: it can see what the panels are generating and adjust charge rate accordingly. The Zappi GLO's Eco+ is a different animal — purpose-built, three-mode, integrated with the wider myenergi ecosystem including the eddi hot-water diverter and libbi battery. (That ecosystem link matters: if you already own a myenergi product, the Zappi GLO slots in without a second app or a second account.)

What the Hypervolt buys you for £26 more

Three things, concretely.

Build quality. IP66 plus IK10 — the Hypervolt is rated against powerful water jets and significant impact. The Zappi GLO's IP65 is fine for rain; the Hypervolt's rating is fine for a football. If the charger sits on an exposed wall beside a shared driveway, this is not a trivial distinction.

Cable reach. The Zappi GLO comes with a 6.5-metre tethered cable. The Hypervolt starts at 5 metres but offers 7.5-metre and 10-metre options — the 10-metre version reaches further than any other tethered charger on the market. Useful if the consumer unit sits at the opposite end of the house from the parking spot.

Extendable warranty. Both ship with 3 years. Hypervolt offers a 5-year extension for £100. Myenergi does not. Over a decade on the wall, that extra cover is worth considering — charger electronics do age.

The Hypervolt also edges ahead on weight (4.5 kg vs 5.4 kg) and physical footprint (270 × 170 × 110 mm vs 439 × 282 × 130 mm). Neither is a buying reason on its own, but if wall space is tight, the Hypervolt is noticeably more compact.

What neither charger does as well as cheaper alternatives

Neither is the cheapest smart charger. The Tesla Wall Connector at £475 undercuts both by over £100 and handles manual off-peak scheduling on fixed tariffs like Octopus Go without complaint. For a single-car household on a fixed off-peak window and no solar panels, neither the Zappi GLO nor the Hypervolt Home 3 Pro justifies the premium over the Tesla.

Neither is the strongest on variable tariffs either. The Ohme Home Pro at £539 remains the benchmark for half-hourly price chasing on Octopus Agile — a job neither the Zappi nor the Hypervolt handles with the same granularity.

Both chargers are OZEV-approved, so eligible renters and flat owners can claim the £500 grant — reducing the Zappi GLO to £99 and the Hypervolt Home 3 Pro to £125 before installation. At those post-grant prices, the decision becomes almost entirely about whether you have solar panels.

The verdict

Buy the myenergi Zappi GLO if:

• You have solar panels — Eco+ is the best surplus-solar charging mode available on any UK home charger
• You already own myenergi hardware (eddi, libbi) and want a single ecosystem
• You value the 22kW three-phase option for a future upgrade

Buy the Hypervolt Home 3 Pro if:

• You have no solar panels and want a charger that handles tariff scheduling, load management, and daily use without fuss
• You need a cable longer than 6.5 metres — the 10-metre option is unmatched
• You want the option of a 5-year warranty for £100

For most buyers without solar, the Hypervolt Home 3 Pro is the safer pick — it does nothing badly, it is built to survive a decade on an exposed wall, and its UK phone support is a genuine comfort when something eventually needs attention. For solar homes, the decision is already made. The Zappi GLO does the one thing that matters most, and it does it better than anything else on the market.
