myenergi Zappi vs Hypervolt Home 3 Pro

The myenergi Zappi and the Hypervolt Home 3 Pro both offer full solar diversion, so a solar home genuinely can’t pick wrong on the core feature. The split is elsewhere. The Zappi is the deeper solar ecosystem; the Hypervolt is the better ownership package — a 5-year warranty, a lower hardware price and native Intelligent Octopus Go support.

Where the myenergi Zappi wins

The Zappi’s eco and eco+ modes remain the benchmark for charging a car from surplus generation, and the unit doubles as a hub for the wider myenergi ecosystem — add the brand’s home battery or immersion diverter later and everything coordinates through one system. That matters if your solar setup is a project rather than a one-off purchase.

It is also the more flexible unit. The Hypervolt Home 3 Pro is single-phase 7kW only; the Zappi comes in 7kW single-phase or 22kW three-phase, and offers Ethernet alongside Wi-Fi. Installed prices start lower too — from around £800 against the Hypervolt’s £1,025 — though the Zappi’s range runs wider, up to £1,500.

Where the Hypervolt Home 3 Pro wins

The ownership case. Hypervolt backs the Home 3 Pro with a 5-year warranty against the Zappi’s 3, rates the unit at IP66, and prices the hardware at £625 — £154 under the Zappi’s £779. Its installed range is tighter as well: £1,025 to £1,225, against £800 to £1,500 for the Zappi, so quotes are more predictable.

On tariffs it is the stronger unit. The Hypervolt supports Intelligent Octopus Go natively and works with OVO Charge Anytime; the Zappi’s listed integration is OVO Charge Anytime alone. And its solar matching is full diversion too, so choosing the Hypervolt doesn’t mean giving up surplus-PV charging.

The deciding factors

Price. £154 separates the hardware (£625 vs £779). Installed, the ranges overlap: the cheapest realistic install here is a Zappi at £800, but so is the most expensive at £1,500. Get quotes for both.

Warranty. Five years plays three. On a unit bolted to an outside wall for a decade, two extra years of cover is the clearest single advantage either charger holds.

Solar and tariff fit. Both are grant-eligible, both come tethered or untethered, both do full solar diversion at 7kW. Take the Zappi if you have — or plan — a myenergi battery or immersion diverter, or a three-phase supply. Take the Hypervolt if you’re on Intelligent Octopus Go, since it’s the only one of the pair with native support.

Whichever way you lean, installed prices swing by hundreds of pounds between quotes — find a home charger installer and get a fixed price for your wall.
