Collecting current: Collecting the DC output current of multiple photovoltaic module strings together and transmitting it to the inverter through a cable.
Protection system: By using protective devices such as fuses and circuit breakers, it prevents faults such as overcurrent and short circuit, and protects photovoltaic systems and equipment.
Monitoring and management: Real time monitoring of the operation status of the photovoltaic system through the built-in monitoring module, providing data support.
Reduce the number of cables: By collecting the output current of multiple photovoltaic module strings, reduce the number of cables and simplify wiring.
Improve installation efficiency: Simplifying wiring can improve installation efficiency and reduce installation costs.
Weather resistance: Made of weather resistant materials, it can operate stably for a long time in various harsh environments.
Protection level: It usually has a high protection level (such as IP65) to prevent dust and moisture from entering, ensuring the normal operation of internal components.
Multiple protection: Ensure the safe and stable operation of the system through protective devices such as fuses, circuit breakers, and lightning protection modules.
Fault isolation: When a photovoltaic module string fails, the fault can be quickly isolated to avoid affecting the operation of the entire system.
The photovoltaic DC combiner box is an important component of the photovoltaic power generation system, which collects the output current of multiple photovoltaic module strings, simplifies wiring, and improves the reliability and safety of the system. It has the characteristics of multiple protections, real-time monitoring, strong environmental adaptability, and easy maintenance, and is widely used in scenarios such as home roofs, commercial buildings, and large-scale ground mounted photovoltaic power stations. When selecting and installing a combiner box, factors such as system capacity, protective devices, and monitoring functions should be fully considered to ensure the safe and stable operation of the system.
