myenergi Zappi GLO vs Andersen Quartz

£599 for solar brains vs £672 for a seven-year promise

These two chargers occupy similar shelf space — both above £500, both IP65, both available tethered with Type 2 — but they solve different problems. The myenergi Zappi GLO at £599 is a solar-diversion computer that happens to charge cars. The Andersen Quartz at £672 is a handsome, long-warranty charger that happens to have a CT clamp for solar.

• Zappi GLO — three solar modes (Fast, Eco, Eco+), myenergi ecosystem, 3-year warranty, £599.
• Andersen Quartz — eleven finishes, 7-year warranty, Intelligent Go and OVO integration, £672.

The £73 gap between them is small. What it buys you depends entirely on whether you have panels on the roof.

The Zappi GLO earns its price on solar — and only on solar

Eco+ mode is the Zappi's reason for existing. It charges your car exclusively from surplus solar generation, drawing nothing from the grid. Eco mode blends grid and solar. Fast mode ignores the sun entirely. No other charger in this price range offers that three-way split with the same granularity, and the Zappi slots into the wider myenergi ecosystem — the eddi for hot-water diversion, the libbi for battery storage — so surplus energy gets routed where it is most useful, not just dumped into the car.

Without solar panels, none of this matters. At £599, the Zappi GLO becomes an expensive 7kW charger with Wi-Fi scheduling and no particular tariff advantage. On Octopus Intelligent Go, the Zappi does not negotiate extra off-peak slots the way an Ohme Home Pro does. On Octopus Agile, it cannot chase half-hourly pricing. If your roof is bare, the Zappi is the wrong charger — and the solar buyers' guide explains who it is right for.

What the Andersen Quartz's £73 premium buys

Four extra years of warranty. That is the headline. Seven years is matched in the catalogue only by the Andersen A3 and the Simpson & Partners Home 7 — and the A3 costs £900. For a charger bolted to an outside wall, exposed to British weather year after year, a 7-year guarantee is a material advantage over the Zappi's 3-year cover.

The Quartz is also smaller — 286 × 172 × 110 mm against the Zappi's 439 × 282 × 130 mm — and comes in eleven standard finishes with optional Accoya and carbon inserts. If your charger faces the street or sits beside the front door, the Quartz looks deliberate rather than industrial. PEN fault detection is built in, which means no earth rod and a cleaner install.

It does have a CT clamp for solar diversion, branded Adaptive Fuse. But this is load management with a solar-aware component, not the three-mode surplus-routing the Zappi provides. If solar optimisation is the priority, the Zappi is the more capable tool. If solar is a nice-to-have alongside grid charging, the Quartz handles it adequately.

The OZEV question

The Zappi GLO is OZEV-approved. The Andersen Quartz is not confirmed on the current eligible-chargepoint list. For grant-eligible buyers — renters and flat owners — this matters: the £500 OZEV grant would bring the Zappi GLO's unit cost down to £99, while the Quartz may not qualify at all. Check the list before committing. If the grant applies to you and the Quartz is not on it, the decision is made for you.

Smart-tariff fit

Neither charger is the tariff specialist. The Quartz integrates with Intelligent Octopus Go and OVO Charge Anytime, which is useful — 8p/kWh across six off-peak hours, or OVO's 14p/kWh managed rate. The Zappi supports smart-tariff scheduling through the myenergi app but cannot match the Ohme Home Pro's half-hourly Agile optimisation. If tariff intelligence is your primary concern, neither of these is the right charger; the Ohme Home Pro at £539 costs less than both and does more with variable rates. Our Ohme vs Zappi GLO comparison covers that angle in detail.

Which to buy

Buy the myenergi Zappi GLO if:

• You have solar panels and want surplus energy routed to the car automatically
• You already own — or plan to buy — other myenergi kit (eddi, libbi)
• You are eligible for the £500 OZEV grant and want confirmed approval

Buy the Andersen Quartz if:

• You have no solar panels and value a 7-year warranty over solar modes you will never use
• Aesthetics matter — you want a charger that comes in eleven finishes and fits a visible wall
• You are on Intelligent Go or OVO Charge Anytime and need integration with those tariffs

For most buyers with solar, the Zappi GLO is the right charger at the right price. For most buyers without solar, the Quartz's longer warranty and smaller footprint justify the £73 — though a Tesla Wall Connector at £475 or an Ohme Home Pro at £539 would do the same electrical job for less money. The Quartz is the charger you buy when you care how the thing looks on the wall and want seven years of cover behind it. The Zappi is the charger you buy when the sun is doing the work.
