myenergi Zappi GLO vs Enphase IQ EV Charger 2

£451 and an ecosystem divide

Both chargers want the same buyer — someone with solar panels who would rather charge a car from the roof than from the grid. The myenergi Zappi GLO costs £599, diverts surplus from any brand of panel, and slots into the broader myenergi ecosystem of hot-water diverters and home batteries. The Enphase IQ EV Charger 2 costs £1,050, diverts surplus with fine 1A granularity — but only speaks fluently to Enphase microinverters and the IQ Battery. That £451 gap is the price of loyalty to a single vendor.

• Zappi GLO — £599, works with any solar system, OZEV-approved, 22kW three-phase option, 3-year warranty.
• Enphase IQ EV Charger 2 — £1,050, best inside an all-Enphase home, 7.5-metre cable, 5-year warranty, OZEV approval not confirmed.

The Zappi GLO doesn't care who made your panels

This is the practical difference that matters most. The Zappi GLO's Eco+ mode diverts surplus solar regardless of inverter brand. Pair it with a CT clamp on the supply, and the charger adjusts draw to match what the panels are producing. Add an eddi — actually, no external links — add a myenergi eddi for hot-water diversion and a libbi battery, and the whole house runs on one app.

The Enphase, by contrast, reaches its best behaviour only when it can talk to an Enphase IQ Gateway, Enphase microinverters, and ideally an IQ Battery. Its AI-led source selection — choosing between solar, battery, and grid — is a genuine technical achievement, reacting to solar changes roughly every 30 seconds in 1A increments from as little as 1.38 kW of surplus. But that intelligence is locked behind the Enphase ecosystem. Without the gateway, you have a £1,050 dumb charger with a long cable.

Total cost tells the real story

Hardware alone: £599 against £1,050. But the gap widens further.

Install costs for the Zappi GLO sit in the standard £400–£600 range. The Enphase's typical install runs £900–£1,300 — partly because the unit weighs 11 kg (the Zappi is 5.4 kg), partly because integrating it with the Enphase gateway and existing wiring takes longer.

Then there is the grant. The Zappi GLO is OZEV-approved, so eligible renters and flat owners can claim the £500 grant against it. The Enphase's OZEV approval is not confirmed on the current list. That means a grant-eligible buyer could pay £599 for the Zappi and have the £500 cover the unit almost entirely, contributing to install costs too. The Enphase buyer, at £1,050 with no grant certainty, faces a total outlay that could be double.

Where the Enphase earns its keep — and where it doesn't

The Enphase has the longer cable: 7.5 metres against the Zappi's 6.5 metres. It has a 5-year warranty against 3. Its MID-certified metering (±1% accuracy) and built-in PEN fault protection are properly specified. OCPP 2.0.1 and ISO 15118 hardware readiness suggest the unit is built for a decade of firmware updates.

None of that addresses its weakness on tariffs. The Enphase has no direct API integration with Octopus Intelligent Go, Octopus Agile, or any other half-hourly UK tariff. The Zappi GLO supports smart tariffs through the myenergi app — not as elegantly as the Ohme Home Pro, which remains the benchmark for tariff optimisation, but enough to schedule around off-peak windows on Octopus Go or EDF GoElectric. The Enphase, left to its own devices, charges when you tell it to or when the sun is out. That is a meaningful limitation for anyone without enough solar to cover most of their driving.

The verdict

Buy the myenergi Zappi GLO if:

• You have solar panels from any manufacturer and want surplus diversion without ecosystem lock-in
• You want the OZEV grant — the £500 covers most of the £599 unit price for eligible buyers
• You might add a myenergi eddi or libbi later and want one app for the lot

Buy the Enphase IQ EV Charger 2 if:

• You already run Enphase microinverters and an IQ Battery and value single-app control over every energy device in the house
• The 7.5-metre cable and 5-year warranty matter enough to justify the premium
• You are comfortable with the OZEV uncertainty and the higher install cost

For the large majority of UK solar homes, the Zappi GLO is the right charger. It costs £451 less, works with whatever is already on the roof, and qualifies for the grant. The Enphase is a fine piece of hardware trapped inside a narrow use case — if you are not already an Enphase household, you are paying a premium for integration you cannot use. Buyers who want tariff smarts more than solar diversion should look at the Ohme Home Pro vs Zappi GLO comparison instead; those exploring broader solar-charger options will find our best EV charger for solar guide covers the full field.
