Zaptec Go 2 vs Sync Energy Wall Charger 2

The Sync Energy Wall Charger 2 is £345 cheaper at £362 compared to the Zaptec Go 2 at £707. Note: the Sync Energy Wall Charger 2 price is socketed Wi-Fi/LAN; tethered from £302.

When you factor in professional installation (typically £400–£600), the total installed cost for the Zaptec Go 2 is approximately £1107–£1307, while the Sync Energy Wall Charger 2 comes in at around £762–£962. Fully installed, the Sync Energy Wall Charger 2 remains the more affordable option.

The Zaptec Go 2 (7.4kW / 22kW) supports three-phase charging at up to 22kW, while the Sync Energy Wall Charger 2 is single-phase only at 7.4kW. On the standard UK single-phase supply (95% of homes), both charge at roughly the same speed. Three-phase is only relevant if your property has a three-phase electrical supply.

On a standard UK single-phase supply, both will charge a Tesla Model 3 Long Range (75kWh battery) from 20% to 80% in approximately 5–6 hours overnight. Even a Tesla Model Y with its larger battery completes a typical daily top-up well within an overnight window. For the vast majority of UK Tesla owners, single-phase 7kW charging is more than sufficient — you'll wake up to a full battery every morning.

The Zaptec Go 2 offers: Zaptec app, Scheduled charging, V2G-ready, MID-approved energy meter, 4G connectivity (subscription-free), OCPP 1.6J compliant. The Sync Energy Wall Charger 2 offers: Sync Energy app, TariffSense scheduling, SolarCharge (solar diversion), Dynamic load balancing, OCPP 1.6J, Energy monitoring, OTA updates, Wi-Fi + Ethernet + Bluetooth, Interchangeable fascia plates (9 colours), RFID (on select models), Built-in PEN fault protection.

Breaking these down by category: for connectivity, the Zaptec Go 2 uses 4G connectivity (subscription-free), while the Sync Energy Wall Charger 2 uses Wi-Fi + Ethernet + Bluetooth. For energy management, the Zaptec Go 2 provides MID-approved energy meter, compared to the Sync Energy Wall Charger 2's Sync Energy app, Dynamic load balancing, Energy monitoring. Solar and scheduling features are covered in the dedicated sections below.

The Sync Energy Wall Charger 2 supports solar integration, allowing you to divert surplus solar energy to charge your Tesla. The Zaptec Go 2 does not have built-in solar diverting. If you have solar panels (or plan to install them), this is a significant advantage for the Sync Energy Wall Charger 2.

The Sync Energy Wall Charger 2 supports solar diversion through its energy management system. This means it can dynamically adjust the charge rate to match your available solar surplus, minimising grid import. Without built-in solar support, the other charger would need a separate solar diverter or manual scheduling to take advantage of solar generation.

The Sync Energy Wall Charger 2 integrates with smart energy tariffs, automatically charging at the cheapest off-peak rates. The Zaptec Go 2 doesn't have built-in smart tariff integration — you'd need to set manual charging schedules or rely on your car's built-in timer. If you're on (or considering) a smart tariff, this gives the Sync Energy Wall Charger 2 a meaningful advantage in running costs.

The Sync Energy Wall Charger 2 supports smart tariff scheduling with popular EV tariffs including Octopus Go (~8.5p/kWh) and similar time-of-use plans. The most popular UK EV tariffs include Octopus Intelligent Go (~7p/kWh), Octopus Go (~8.5p/kWh), OVO Charge Anytime (~14p/kWh), and British Gas EV Power+ (~7.9p/kWh). Check compatibility with your specific energy provider before making a decision.

The Zaptec Go 2 comes with a 5 years warranty, while the Sync Energy Wall Charger 2 offers 3 years. The Zaptec Go 2 offers 2 years more coverage, giving you added peace of mind. Both are OZEV-approved and suitable for outdoor installation — a longer warranty provides more peace of mind for a product that lives outside year-round and is exposed to British weather.

For weatherproofing, the Zaptec Go 2 is rated IP54 (weatherproof) (splash-proof — protected against splashing water from any direction), while the Sync Energy Wall Charger 2 is rated IP65 + IK10 (fully weatherproof, impact-resistant) (jet-proof — protected against water jets from any direction). A higher IP rating means better protection against rain, hose water, and dust. In practical terms, any rating of IP54 or above is suitable for a UK outdoor installation, but a higher rating provides extra confidence in extreme weather — particularly relevant if your charger is exposed rather than sheltered under a car port.
