Zaptec Go 2 vs Rolec EVO: future-proof or British-built?

The £51 question: pay for the future, or save on the install?

At £449, the Rolec EVO is a British-built unit with a five-year warranty and enough built-in protection to shave real money off the installer's bill. At £500, the Zaptec Go 2 is the only AC home charger in the UK certified V2G-ready, with a MID-approved meter and free 4G baked in. The £51 gap is almost beside the point. These chargers aren't competing on price — they're competing on which side of the EV transition you're shopping for.

The shortest version:

• Rolec EVO — the pragmatic pick. Cheaper unit, cheaper install, solar surplus included, made in Boston.
• Zaptec Go 2 — the forward bet. V2G-ready, three-phase-capable, MID-metered, subscription-free 4G.

What the Rolec EVO gives you that the Zaptec doesn't

Two things, really, and both matter today. First, built-in PME/PEN fault detection, plus a Type A RCD and surge protection on board. That removes the need for a separate O-PEN device or earth-rod installation on most jobs — £100–£250 off the install, reliably. On a like-for-like fit, the Rolec EVO is effectively £150–£300 cheaper than the Zaptec Go 2 once the electrician has finished.

Second, solar. The EVO ships with a CT clamp in the box and runs Eco and Eco+ surplus modes out of the app. The Zaptec can do solar diversion too, but only through third-party OCPP integrations — more fiddly, and not what the average homeowner wants to commission. If you have panels and no ambitions beyond charging from them, the Rolec handles it without an extra purchase. If solar is the main event, the dedicated myenergi Zappi GLO is a better target — the Zappi GLO vs Rolec EVO comparison covers that choice properly.

What £500 on a Zaptec actually buys

Three things the Rolec can't offer. Three-phase capability up to 22kW, which matters to perhaps one in twenty UK homes but matters a lot to that one. A MID-approved energy meter — legally certified readings, which is useful if you're billing an employer or landlord for mileage. And subscription-free 4G built in, so it works when your home Wi-Fi drops.

The headline, though, is V2G. The Zaptec Go 2 is currently the only AC unit certified to feed energy back to the grid when bidirectional standards land for home users. This is a genuine differentiator — but it's also a bet. V2G at AC level for domestic customers isn't commercially live in the UK in April 2026. It may arrive in two years. It may arrive in five. The Zaptec is buying you the option. If you don't care about that option, the Easee One at £405 does the everyday job for £95 less, and the Ohme Home Pro actually automates tariff optimisation on something like Octopus Agile, which neither of these do out of the box.

Tariff behaviour — neither is the star pupil

Both chargers will run a schedule on a fixed-window tariff like Octopus Go or E.ON Next Drive without drama. Set 00:30–05:30, walk away. On half-hourly variable tariffs, both lean on OCPP 1.6J integrations rather than native supplier APIs. If you're on Octopus Intelligent Go, which optimises via a direct API to your car or charger, the Ohme ePod at £409 is the cleaner answer. It's worth knowing where the ceiling is on both of these before you buy.

The verdict

Buy the Rolec EVO if:

• You want the lowest total installed cost from a UK manufacturer
• You have solar and want surplus charging without extra kit
• You're on a fixed-window tariff and don't need V2G or three-phase

Buy the Zaptec Go 2 if:

• You have three-phase supply and want the full 22kW
• You need an MID-approved meter for billing or reimbursement
• You plan to use V2G when it arrives

For the overwhelming majority of UK Tesla owners reading this, the Rolec EVO is the unit to put on the wall. It's £51 cheaper on the price tag and £150+ cheaper once the electrician has gone, it handles solar without an add-on, and the five-year warranty from a decade-old British manufacturer is hard to argue with. The Zaptec Go 2 is the right answer for three-phase homes and committed V2G believers — a smaller audience than the marketing suggests, but a real one.
