Let MyBox manage your electrical grid and you will never have your circuit breakers trip due to charging again.



For efficient energy distribution, it is crucial to adjust charging power according to the current load and grid capacity.
MyBox Arm Unit monitors total consumption and passes measured values to charging station control units, maximizing the utilization of charging points and eliminating the need for manual power limitation.

MyBox Arm Unit is ideal for managing up to 200 charging points simultaneously and can control them according to their current load. This is a perfect solution for large-scale fleet management, which thanks to our unit and cloud services will be simpler than ever.
When operating with high-power appliances or industrial machines, the module prevents grid overload thanks to its ability to flexibly respond to changes in consumption. It also offers advanced features such as charging station prioritization.

Charging from PV surplus is handled by the MyBox AC Sensor module, designed for smaller installations. The Arm Unit manages power in large installations and makes sure charging never overloads the main circuit breaker.
In the era of growing numbers of electric vehicles, this module is a key technology for managing charging processes in industrial areas and public spaces.

MyBox Arm Unit
MyBox Arm Unit can simultaneously manage and dynamically control up to 200 charging points. This makes it an ideal solution for large corporate campuses, logistics centers, public parking facilities, and residential complexes with extensive charging infrastructure.
Arm Unit is permanently connected to the MyBox cloud platform via secure Ethernet. You can remotely monitor the status of all charging stations, change configurations, update firmware, track consumption, and generate reports. The cloud platform also enables charging priority settings.
When managing tens to hundreds of charging points, communication reliability and stability are crucial. Ethernet provides deterministic latency, is not susceptible to interference, and guarantees a stable connection even in demanding industrial environments. For critical infrastructure, wired connectivity is the industry standard.
Arm Unit monitors grid load in real time and can respond flexibly within seconds. When consumption in the building suddenly increases, it immediately reduces charging station power; when consumption drops, it automatically increases power. This dynamic regulation protects the grid from overload without manual intervention.
Arm Unit allows setting priorities for individual charging points. When available power is insufficient, the system automatically allocates energy to higher-priority stations and reduces power at less important points. Priorities can be set statically or dynamically changed via the MyBox cloud platform according to current operational needs.
Arm Unit is installed in the distribution panel and requires 24 V DC power supply with a maximum consumption of 12 W. The module has compact dimensions of 70 × 90 × 60 mm, metal construction with IP20 protection rating, and operates in a temperature range of -25 to 85 °C. An Ethernet connection to the local network is required for communication.
