This is a 10MW photovoltaic power generation project at the Turpan Desert Photovoltaic Demonstration Station in Xinjiang. Located in the Turpan desert, 15km from the city center, it allows for local power consumption. The project has a capacity of 10MW (lower-range medium-sized), generating approximately 18 million kWh annually and providing 1,800 equivalent hours of annual utilization. It utilizes 18,200 550W solar panels, each rated at approximately 12A, and 46 225kW high-voltage inverters.

Choosing the right combiner box is a crucial step in ensuring the efficient, safe, and long-term operation of a photovoltaic system. As an intermediate link between solar panels and inverters, it can collect direct current from multiple panel strings, protect the system from electrical faults, and support monitoring functions. Faced with numerous optional products, here is a comprehensive guide to help you make an informed decision.

In photovoltaic power generation systems, apart from the "star equipment" such as solar panels and inverters, there are two "unsung heroes" quietly safeguarding the system's safety - circuit breakers and surge protectors (SPDS). They are like the "fuses" and "lightning rods" of the power system, constantly protecting the entire photovoltaic system from electrical faults and lightning strikes. This article will take you through the significant roles of these two key protective devices in photovoltaic systems.
