GHL-100 series smart PV combiner box is used to connect PV modules and inverters (or connect inverter through DC distribution cabinet) and provide lightning and overcurrent protection, as well as measure and monitor the status of PV array’s current, voltage, surge arrester and circuit breaker through intelligent measurement and control module.
The combiner box is internally equipped with PV-dedicated DC lightning protection module, DC fuse, anti-reverse diode (equipped selectively according to the user) and circuit breaker. The intelligent monitoring unit possesses working status indication, alarming and telecommunications, etc., which enables the user to timely master the working status of PV modules, making full use of PV power generation system and facilitating fault location.
The professional electrical design and production technology, outstanding electrical components and the cabinet structure with high protection class ensure a reliable, long-term and stable operation and meet the requirements in outdoor environment, such as waterproof, dustproof, rustproof, sun block, and salt-mist proof. Moreover, the reasonable lay-out of internal structure and safe, simple, and beautiful wiring is convenient for field connection and daily maintenance. .
The combiner box adopts the monitoring module specially developed for PV combiner box by XJ and employs current measurement component with reliable performance, suitable measuring range and high sensitivity and accuracy to monitor the current of each PV string. Meanwhile, the combiner box also possesses the functions of telecommunications and alarm. And the communication protocol can select RS485, CAN and wireless.
