Huawei has introduced a new generation of controllers for commercial and industrial energy systems — SmartLogger 5000B and SmartMGC 5000B. The new solutions replace the SmartLogger 3000B series and are based on an upgraded hardware platform which, according to the company, delivers 3.5 times higher performance than the previous generation.
Controllers are a central element in the management of modern energy systems. They enable interaction between solar inverters, battery energy storage systems, electric vehicle charging stations and Huawei’s FusionSolar cloud platform. Through these devices, energy systems can implement self-consumption maximisation, export limitation, battery charge and discharge control, as well as integration with digital monitoring and management systems.
Huawei continues to develop the AC-coupling architecture, where inverters and energy storage systems are connected to a common AC grid. This approach provides greater scalability, improves system reliability and simplifies the modernisation of existing energy facilities.
SmartLogger 5000B is designed for grid-connected on-grid systems. The controller supports direct measurement of grid parameters, enabling zero export, power limitation and peak shaving without the need for additional meters.
A key new product is the SmartMGC 5000B microgrid controller, designed for microgrids operating in island mode. The solution can automatically switch the system from grid-connected mode to autonomous operation and back, ensuring uninterrupted power supply for critical loads.
According to Huawei, the system can detect a grid fault within 4 ms and send a command to the circuit breaker within another 1 ms. The total switching time depends on the type of switching equipment and may reach 15–20 ms when fast semiconductor breakers are used.
SmartMGC 5000B also supports automatic control of battery energy storage operation modes, reconnection to the grid after power restoration and Black Start functionality — enabling the microgrid to start without an external power source when solar generation is available.
The new controllers can operate both independently and under the control of external EMS systems via MBUS TCP. They also support integration with diesel generators and automatic generator start control.
Huawei’s new generation of controllers is aimed at supporting the development of commercial energy storage systems, microgrids and solutions that strengthen business energy resilience. The company has placed particular emphasis on response speed, automation and island mode support, making SmartMGC 5000B an important element of modern C&I solutions for business energy independence.
