Reliable communication technology for PV Solar plants. It converges all ports, converts protocols, and collects and stores data from connected devices. It centrally monitors and manages PV and energy storage systems, providing real-time information to O&M teams via the Huawei FusionSolar Management System, where batch software updates can be done with a single click. Each SmartLogger can manage up to 150 inverters using embedded MBUS communication over three-phase AC power cables. It also collects information from EMIs, power meters, substations, PID modules, MBUS CCO modules, and other RS485 devices via COM ports, and allows configuration of SCADA and third-party management systems.
