Sync Energy Wall Charger 2 Review UK: Specs & Verdict

The Sync Energy Wall Charger 2 (model EVWC2S7G) is a 7.4kW single-phase home EV charger that costs less than most big-name rivals and has built-in protection that can remove the need for an earth rod. It was sold as the BG Sync EV charger before the Sync Energy rebrand, and it is the budget-tier option many installers fit. This Sync Energy Wall Charger 2 review works through the manufacturer's datasheet and one independent UK installer review to cover specs, solar and tariff support, price, and who it suits.

Sync Energy Wall Charger 2 specs

The EVWC2S7G is the untethered 7.4kW model with Wi-Fi and LAN: a Type 2 socket with auto-lock, delivering up to 32A on a single-phase supply. These figures come from Sync Energy's own datasheet.

• Output: 7.4kW, 32A, Mode 3, 220–240V single phase; minimum charge current configurable from 6 to 32A
• Connector: Type 2 socket with auto-lock (a tethered version is also made)
• Protection: built-in PEN fault protection (earth disconnection), built-in Type A RCD (6mA DC and 30mA AC), over-current and fault protection
• Connectivity: Wi-Fi and Ethernet on this model; 4G and RFID on the EVWC2S7GG and EVWC2S7GGR versions; OCPP 1.6J with over-the-air updates
• Metering: internal meter (2% accuracy), with the option to connect an external RS485 Modbus meter; a load management kit is supplied with the single-phase variants
• Size: 305 × 201 × 115mm; UV-stabilised polycarbonate housing; operating range −25°C to +40°C
• Warranty: three years

One detail to check: the datasheet lists the enclosure as IP55 and IK10 and is marked as correct as of June 2023, while an installer review quotes IP65. Both are suitable for outdoor mounting, but confirm the rating printed on the unit you are sold.

No earth rod needed

The datasheet says no earth rod is required because the charger has integrated open PEN conductor protection. On a typical PME (TN-C-S) supply that can save groundwork, which is a large part of why budget chargers cost less to fit. It does not remove the installer's responsibility: they must still assess your supply, size the circuit protection (the datasheet suggests a 40A MCB or 30mA Type A RCD, depending on cable type and route) and sign off the work. Our EV charger installation guide and home EV charger requirements page explain what that involves.

Does it work with solar panels?

The Sync app has manual and automatic solar charging modes, according to an independent UK installer review. Sync Energy's datasheet does not describe solar behaviour, so treat this as installer-reported rather than manufacturer-documented. Ask what sensor hardware the mode needs and what the minimum charge rate is: the datasheet's 6A floor is roughly 1.4kW, so on a cloudy day with less than that spare, expect some grid import. If surplus-only charging is your main goal, compare it with chargers designed around diversion in our best EV charger for solar panels guide or the myenergi Zappi review.

Smart tariffs and the app

The datasheet says the app is powered by Monta and that 4G data is included for three years on the connected models when used with Monta's included package. The installer review describes a "Tariff Sense" feature that connects to tariffs that do not need control over the charger, naming British Gas and OVO Charge Anytime, and says the charger works with Intelligent Octopus Go but is controlled through the Octopus app. A retailer-side source disagrees and says it is not on Octopus's compatible list. Because sources conflict, check the current list with your supplier before buying, and see our best EV charging tariff guide. If direct Intelligent Octopus Go control matters most, the Ohme ePod is the safer comparison.

Smart charge point rules

Sync Energy's datasheet states the charger is compliant with the Electric Vehicles (Smart Charge Points) Regulations 2021, including Schedule 1, and lists tamper detection and over-the-air updates. Those rules are what require a smart-capable, secure home charger in Great Britain.

How much does it cost?

Prices vary widely. Retailer listings for the Wi-Fi and LAN untethered model run from about £305 to £315 ex VAT in trade shops, while one installer quotes about £500 for the unit alone and about £849 with standard installation. Our product data lists around £292. Get an itemised quote, and check current EV charger grant rules before assuming any support applies.

Pros and cons

Strengths: low price; built-in PEN protection and RCD; 7.4kW with configurable current; OCPP 1.6J and optional 4G and RFID models; swappable coloured fascias; three-year warranty.

Weaknesses: three years is shorter than some rivals' five; solar and tariff behaviour is not documented in the datasheet; the base model has no RFID or 4G; the published datasheet is dated 2023; plain styling.

Who should buy the Sync Energy Wall Charger 2?

It suits households on a standard or fixed-window off-peak tariff that want a compliant, well-priced 7.4kW charger and a straightforward install. It is a weaker fit if you need documented solar-only charging or guaranteed direct integration with smart tariffs. For alternatives, see the Project EV Apex 7S review or our best home EV charger shortlist, and always use a qualified installer.
