The important role of surge protectors in combiner boxes

Surge protectors play an important protective role in PV combiner boxes. PV combiner boxes are a key component in PV power generation systems. They collect the DC power from multiple PV strings and then transmit it to the inverter. The following are the main functions of surge protectors for PV combiner boxes:

1. Lightning protection: When a surge current occurs, the surge protector can quickly conduct and release the excess current through the ground wire, thereby protecting the equipment in the circuit from the impact of large currents.

2. Improve system reliability: With the protection of surge protectors, the operation of PV systems is more stable, the equipment failure rate caused by surges is reduced, and the overall reliability and efficiency of the system are improved.

3. Extend equipment life: Surge protectors reduce the impact on equipment caused by voltage and current transients, thereby helping to extend the service life of PV combiner boxes and other equipment in the system.

4. Safety protection: Surge protectors usually also have thermal protection and arc extinguishing functions, which can quickly disconnect the circuit when a component fails to prevent fire and further equipment damage.
