1.What is the main function of a junction box? The main functions include summarizing multiple DC power sources, providing overcurrent protection, monitoring system performance, isolating circuits, and sometimes providing inverter functions (converting DC to AC). 2. What does the maintenance work of the combiner box include? The maintenance work mainly includes regularly checking the fastening of wires and connections, cleaning the junction box to prevent dust accumulation, checking whether the waterproof seal is intact, and regularly checking whether the electrical performance is normal. 3.How to diagnose and solve common problems with combiner boxes? Common problems may include circuit disconnection, overheating, blown fuses, or relay malfunctions. When diagnosing these issues, a voltmeter and ammeter should be used to check the input and output, check all connections for tightness, and confirm that the protective devices are working properly. | ||||||||
