Where are photovoltaic combiner boxes generally used?

Photovoltaic (PV) combiner boxes are typically used in solar photovoltaic power systems. Their main function is to aggregate the current produced by multiple PV modules (also known as solar panels) and then transmit it to the inverter. This is done to improve the efficiency of the system and to facilitate management. Specifically, PV combiner boxes are applied in the following scenarios:

Rooftop Solar Systems: In rooftop solar installations on residential or commercial buildings, combiner boxes are used to consolidate the current from multiple solar panels on the roof.

Ground-Mounted Solar Systems: In large-scale, ground-mounted solar power plants, combiner boxes play a key role in centralizing the electrical output from PV panels spread over a large area.

Floating Solar Systems: In solar installations on water bodies, such as floating solar panels on lakes and reservoirs, combiner boxes are also necessary to integrate the current.

PV combiner boxes are crucial for enhancing the safety of solar systems, reducing line losses, and simplifying electrical wiring. They are typically equipped with safety features such as lightning protection and overload protection to ensure the safe and stable operation of the entire system.
