Solar Combiner Box Monitoring Device with LCD Display and Fault Alarm

PV Combiner Box Intelligent Monitoring Device is designed to monitor and manage the operating status of photovoltaic DC systems in real time. It provides reliable data acquisition and alarm functions to ensure safe and efficient operation of solar power plants.

The device supports multi-circuit monitoring and can collect key parameters such as string current, DC voltage, power status, and fault signals. With a clear LCD display and LED indicators, system status and alarms can be checked easily on site. When abnormal conditions occur, the device triggers visual and remote alarm signals, allowing quick response and preventive maintenance.

Integrated with RS485 communication, it enables seamless connection to upper-level monitoring systems or SCADA platforms for centralized management. This helps reduce operation and maintenance costs while improving system reliability.
