Product Description

The combiner box is a wiring device in the photovoltaic power generation system that ensures the orderly connection and confluence function of photovoltaic modules. This device can ensure that the photovoltaic system is easy to cut off the circuit during maintenance and inspection, and reduce the range of power outage in case of photovoltaic system failure. The combiner box means that the user can connect a certain number of photovoltaic cells with the same specification in series to form a photovoltaic tandem, and then connect several photovoltaic tandem to the photovoltaic combiner box in parallel. After converging in the photovoltaic combiner box, through the controller, DC distribution cabinet, Solar inverter, and AC distribution cabinet, a complete photovoltaic power generation system can be formed to achieve grid connection with the mains.

Frequently Asked Questions

What is the purpose of a PV combiner box in a solar system?

A PV combiner box functions as a central wiring device that facilitates the orderly connection and confluence of multiple photovoltaic modules. It simplifies system wiring, makes it easy to isolate circuits during maintenance, and limits the range of power outages in the event of a system failure.

What safety and protection features are integrated into the box?

The combiner box offers high reliability by including a DC fuse, a DC Surge Protective Device (SPD), and a DC circuit breaker or DC load isolation switch to protect the system against overcurrent and voltage surges.

Can this combiner box be used outdoors?

Yes, it features an IP65 protection grade design which makes it waterproof, dustproof, and anti-ultraviolet. It has been strictly tested for performance in both high and low temperature environments (-25 °C to +55 °C).

What types of solar modules is it compatible with?

This combiner box is highly versatile and is compatible with single crystal silicon solar modules, polycrystalline silicon solar modules, and thin-film solar modules.

What are the default and optional materials for the box?

The box material is listed as PVC/ABS shell options, and it is also customizable with box bodies made of cold-rolled steel or other metal materials depending on application requirements.
