The Sigenergy Sigen EV AC Charger 7 kW is a single-phase smart EVSE with a 5-metre tethered Type 2 cable, built-in 4G, Wi-Fi and Ethernet and a fully integrated PEN protection device — compliant with IET-01:2024 and BS 7671:2018+A2:2022 Section 722. No separate external PEN disconnector is required on site. The integrated RDC-PD (AC 30 mA + DC 6 mA, IEC 62955) also eliminates the need for an external Type B RCD.
Controlled via the mySigen app, it supports Sigen AI Mode (dynamic tariff scheduling), PV Surplus Charging, Battery Boost Charging and Dynamic Load Management (with Sigen Power Sensor) — all standard features, not paid extras. The Click-in 15-minute install, three cable entry points (top, bottom, rear) and IP65 + IK10 enclosure rated to +55 °C with no derating make it suitable for permanent outdoor installation anywhere in the UK.

OPERATING TEMP
Qualified installer required. Must be installed by a registered electrician per BS 7671, IET-01:2024 and your DNO's requirements. The built-in PEN and RDC-PD cover those specific requirements; all other Section 722 and installation standard obligations still apply.
Sigen Power Sensor required for DLM. Dynamic Load Management requires the separately purchased Sigen Power Sensor. PV Surplus Charging and Battery Boost need a SigenStor or compatible home energy system. Sigen AI Mode requires active internet.
Typical application. Single-phase UK domestic or light-commercial installation — home garage, driveway carport or workplace. Ideal paired with a Sigenergy solar-and-storage system, or as a standalone smart EVSE with solar integration planned for later.
Key Features
Built-In PEN Protection — UK Market Specific
An integrated PEN breaker complies with IET-01:2024 and Section 722 of BS 7671:2018+A2:2022. No separate external PEN disconnector is required — it is already inside the unit, reducing installed cost and simplifying the cable management around the charger.
Integrated RDC-PD — No External RCD Needed
Built-in AC 30 mA + DC 6 mA residual DC protective device (tested to IEC 62955) meets the requirement for DC fault detection without a separate Type B RCD — both mandatory protection devices are inside the box.
Sigen AI Mode + Solar Surplus Charging
Sigen AI Mode reads live dynamic tariff data and automatically schedules charging when electricity is cheapest. PV Surplus Charging diverts spare solar generation directly to the vehicle — green power first, grid power only when needed.
Dynamic Load Management
The Sigen Power Sensor (sold separately) monitors whole-home consumption in real time. The charger automatically reduces its output current as household load rises — preventing tripped breakers and overloads without any manual intervention.
Click-In 15-Minute Install + Rear Cable Entry
Tool-free Click-in bracket means no separate mounting plate. Three cable entry points — top, bottom and rear — suit any installation layout, including a fully concealed rear-entry for a clean aesthetic. Typical install: 15 minutes hardware; 5 minutes app commissioning.
IP65 + IK10 + −30°C to +55°C
The enclosure is IP65 dust-tight and water-jet proof; the front glass is IK10 impact-rated. Operating range −30 °C to +55 °C with no power derating at 55 °C — fully suitable for UK outdoor installation.

Frequently Asked Questions
What does built-in PEN protection mean for the installer?
On a TN-C-S (PME) supply — the most common type in the UK — BS 7671 Section 722 and IET-01:2024 require a device that disconnects the EV cable if the protective earth neutral conductor fails. Previously this meant specifying and wiring a separate external PEN disconnector. The Sigenergy charger integrates this device internally, eliminating the separate component, reducing cost and simplifying the installation design.
Do I still need a separate RCD or Type B protection?
No. The integrated RDC-PD combines AC 30 mA pulsating and DC 6 mA fault detection (IEC 62955), which meets the Type B RCD requirement for EV chargers. Your installer will still connect the charger to a dedicated MCB in the consumer unit, but no additional external RCD is needed specifically for EV charging.
Does solar PV surplus charging work with non-Sigenergy inverters?
Yes for basic PV surplus charging — the charger supports surplus PV from third-party inverters when the Sigen Power Sensor is installed for whole-home metering. Priority adjustment (ranking the charger against other loads) requires a Sigenergy inverter. OCPP 1.6J ED 2 also enables integration with third-party energy management platforms.
What is needed for Dynamic Load Management?
DLM requires the separately purchased Sigen Power Sensor, which connects to the consumer unit and feeds real-time whole-home consumption data to the charger. Sigen AI Mode (dynamic tariff) needs an active internet connection. RFID and auto-charge modes work without any network connection.
