Product Introduction

The combiner box monitoring unit is a key device used in photovoltaic systems to monitor and manage the operation status of the combiner box, and is widely used in photovoltaic power stations and distributed photovoltaic power generation systems.

Application

: Large scale photovoltaic power station
High voltage and high current design to meet long-distance transmission requirements. Intelligent monitoring integration enhances the efficiency of power station operation and management.

: Distributed photovoltaic system
Compact design, suitable for limited spaces such as roofs and walls. High protection level, adaptable to changing climate environments.

: Intelligent operation and maintenance system
Real time data transmission and remote control functions, supporting preventive maintenance.

: Current and voltage monitoring
Real time monitoring of the current of each branch and the total voltage after convergence, with a measurement accuracy of ± 1%. Supports multiple measurement ranges, such as current measurement from 0 to 20A and DC voltage measurement from 50V to 1200V.

: Equipment status monitoring
Monitor the status of lightning arresters and DC circuit breakers, including on/off status and fault tripping status. Provide temperature monitoring function, which can measure the internal temperature or external environmental temperature of the combiner box.

: Alarm and protection functions
Support upper and lower limit alarms for parameters such as current, voltage, and temperature. Equipped with arc detection function, it can effectively identify potential arc faults.

: Communication and Data Transmission
Equipped with RS485 interface and supporting Modbus RTU protocol, the collected data can be uploaded to the monitoring system. Some monitoring units support wireless communication for remote monitoring.
