A dual socket with advanced smart functionality designed to withstand an on-street environment

The Twin is designed for a high volume streetscape environment and suitable for any semi-public or public space with a 3-phase supply. It offers two back-to back sockets in a vandal-proof steel pillar with curved top surface so waste cannot be left on the charger. The pillar can be brand wrapped if required. The charger incorporates an RFID reader and MID-meter for financial settlement. Its user interface is language-agnostic, with user instructions in icon form and LED charging status lights. Internet connection is via GPRS/Ethernet, with data available via the chosen third party management system provider.

Advanced smart functionality

Market-leading smart functionality. Supports multiple user profiles, pricing hierarchies and financial transaction settlement. It can also communicate with, and respond to, other smart technologies and solutions that share common standards and open protocols.


Engineered to last

All products are designed to be robust, safe, secure and reliable. Built in Alfen’s Dutch factory using A-grade components, all models are rigorously tested and independently certified. Each comes with a standard warranty and optional service package with service level agreement.


Language-agnostic interface

For ultimate simplicity of use, the Twin uses icon instructions and a charging status light to guide the user through the charging process.


Choose and change management system

Can be used with Alfen’s own management system or integrated with any OCPP-compliant back office for registration of energy consumption, historic transactions and remote access for diagnostics and upgrades.


Designed to integrate

All Alfen charging stations are designed to maximise charging speeds while safeguarding the grid connection and optimising energy use. This makes them capable of integration and interoperation with self-generated renewables, energy storage and flexible energy tariffs.


Alfen Smart Charging Network

Network up to 100 Alfen single socket, or 50 double socket, charging stations on a single site. Load balance across all vehicles charging at any one time to maximise charging speeds within the available local grid capacity. Also includes the option to set bespoke charging priorities.
