Maximizing charging density and reducing operational costs through advanced dual-port technology and intelligent energy management.
The Growing Challenge of Scalable EV Charging
As the global transition to electric mobility accelerates, commercial property owners, fleet managers, and retail operators face a significant dilemma: how to provide sufficient charging capacity without skyrocketing infrastructure costs or depleting limited grid resources. Traditional single-port chargers often lead to inefficient space utilization and higher installation expenses per charging point.
The central question for modern enterprises is no longer whether to provide charging, but how to do so profitably and sustainably. This article serves as a strategic roadmap for implementing the Dual AC Wallbox, a solution designed to double charging availability while maintaining a compact footprint and optimizing energy distribution.
What you will learn in this guide:
- The technical architecture and advantages of dual-port charging systems.
- How smart load balancing within a Dual AC Wallbox prevents grid overload.
- Step-by-step considerations for commercial deployment and ROI optimization.
- Compliance and safety standards essential for global operations.
Understanding the Dual AC Wallbox
A Dual AC Wallbox is a specialized EV charging station equipped with two independent charging outlets (typically Type 2) housed within a single enclosure. Unlike standard chargers, these units are engineered to manage two simultaneous charging sessions from a single power feed, effectively doubling the service capacity of a parking spot.
Utilizing advanced AC charger technology, these devices support various power outputs, most commonly 7kW, 11kW, or 22kW per port. By integrating two controllers into one chassis, businesses can significantly reduce the "cost-per-plug" in terms of hardware, cabling, and civil works.
Technical Strategic Deployment of Dual-Port Systems
1. Intelligent Load Management
The primary concern with a Dual AC Wallbox is power distribution. Gresgying utilizes Dynamic Load Balancing (DLB) to monitor total building consumption and adjust the charging speed of each port in real-time. This ensures that even when two vehicles are charging at full capacity, the local transformer is never overloaded.
2. Communication and Connectivity
For commercial applications, support for OCPP 1.6J or 2.0.1 is non-negotiable. This protocol allows the Turbo Wallbox series to communicate with backend management platforms for billing, remote diagnostics, and user authentication via RFID or mobile apps.
3. Robust Environmental Design
Outdoor reliability is critical. Professional-grade units feature IP54 or IP55 ratings and IK10 impact resistance. Whether deployed in the harsh winters of Iceland or the humid climates of Southeast Asia, the internal components remain protected against dust, water, and mechanical stress.
4. Scalability for the Future
Investing in a Dual AC Wallbox is a future-proofing strategy. As fleet sizes grow, having the infrastructure to charge two vehicles per station allows for a modular expansion of workplace charging networks without requiring extensive new electrical permits.

Frequently Asked Questions
Can a Dual AC Wallbox charge two different car models at the same time?
Yes. Each port operates independently. The intelligent controller communicates with each vehicle's BMS to deliver the specific current required, regardless of make or model, provided they use compatible Type 2 connectors.
What are the installation requirements for a 22kW Dual AC Wallbox?
A 22kW dual-port system typically requires a 400V three-phase electrical supply. If the total capacity (44kW for two 22kW ports) exceeds the site limit, our dynamic load management software will automatically balance the load between the two vehicles.
Is the Dual AC Wallbox suitable for public billing?
Absolutely. By connecting the unit to an OCPP-compliant cloud platform, operators can set tariffs, track energy usage, and accept payments via RFID or mobile applications, making it ideal for retail destination charging.
