KEBA KeContact M20 Charging Management Controller - medium - 4G

Managing multiple EV charging points without a central controller leads to overloaded circuits, unnecessary peak demand charges, and inefficient energy use. The KEBA KeContact M20 Charging Management Controller solves this by intelligently coordinating up to 20 charging stations, ensuring balanced loads and lower operating costs. This medium-tier controller with integrated 4G LTE and Ethernet connectivity is ideal for commercial properties, fleet depots, and residential complexes where reliable, remote-managed charging is essential.

Who is it for

Facility managers, installers, and operators of medium-sized EV charging infrastructure who need robust load management, remote monitoring, and future-proof connectivity. It suits parking garages, office buildings, apartment blocks, and fleet hubs with up to 20 charging points.

Main features

• Manages up to 20 charging points with dynamic and static load management, plus peak shaving to avoid costly demand spikes.
• Dual connectivity: 4G LTE for remote access and dual Ethernet ports for local network integration.
• Supports OCPP 1.6J and Modbus RTU/TCP for seamless integration with common backends and building management systems.

Tips

For best results, mount the controller in a protected enclosure near the distribution board. Use the USB port for initial configuration, then switch to remote management via OCPP for ongoing updates and monitoring. Ensure a stable 24 V DC supply and consider a UPS for critical sites to maintain load management during power fluctuations.
