Tesla Wall Connector (Gen 3) vs Rolec EVO

The Tesla Wall Connector (Gen 3) is £24 cheaper at £425 compared to the Rolec EVO at £449.

When you factor in professional installation (typically £400–£600), the total installed cost for the Tesla Wall Connector (Gen 3) is approximately £825–£1025, while the Rolec EVO comes in at around £849–£1049. Fully installed, the Tesla Wall Connector (Gen 3) remains the more affordable option.

The Tesla Wall Connector (Gen 3) (7.4kW / 22kW) supports three-phase charging at up to 22kW, while the Rolec EVO 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 Tesla Wall Connector (Gen 3) offers: Tesla app integration, Scheduled charging, Power sharing (up to 6 units), Wi-Fi connected, OTA updates. The Rolec EVO offers: Rolec EVO app, Charge scheduling, Solar integration (Eco + Eco+ modes), Dynamic load balancing (CT clamp included), RFID (2 cards included), Wi-Fi 6 + Bluetooth 5.0 + Ethernet, OCPP 1.6J, Energy monitoring, PME/PEN fault detection, Built-in Type A RCD + 6mA DC protection.

Breaking these down by category: for connectivity, the Tesla Wall Connector (Gen 3) uses Wi-Fi connected, while the Rolec EVO uses Wi-Fi 6 + Bluetooth 5.0 + Ethernet. For energy management, the Tesla Wall Connector (Gen 3) provides Power sharing (up to 6 units), compared to the Rolec EVO's Dynamic load balancing (CT clamp included), Energy monitoring. Solar and scheduling features are covered in the dedicated sections below.

The Rolec EVO supports solar integration, allowing you to divert surplus solar energy to charge your Tesla. The Tesla Wall Connector (Gen 3) does not have built-in solar diverting. If you have solar panels (or plan to install them), this is a significant advantage for the Rolec EVO.

The Rolec EVO 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 Tesla Wall Connector (Gen 3) comes with a 4 years warranty, while the Rolec EVO offers 5 years. The Rolec EVO offers 1 year more coverage, giving you added peace of mind. The Rolec EVO is OZEV-approved; the Tesla Wall Connector (Gen 3) is not. Both are 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 Tesla Wall Connector (Gen 3) is rated IP44 (indoor/outdoor) (protected against solid objects over 1mm and water splashes from all directions), while the Rolec EVO is rated IP54 + IK10 (weatherproof + highest impact resistance) (splash-proof — protected against splashing water 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.
