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 function of a PV combiner box?
A PV combiner box connects multiple photovoltaic modules in series to form a tandem, and then interfaces these tandems in parallel to centralize the power output. It facilitates easy circuit cut-off during inspection, minimizes power outages, and safeguards the downstream solar power generation system components.
Is this PV combiner box waterproof and suitable for outdoor use?
Yes, it features an IP65 protection grade design, which is waterproof, dustproof, and anti-ultraviolet. It has undergone strict testing for both high and low temperatures, making it highly reliable for outdoor environments.
What safety and protection components are integrated into the box?
The combiner box features integrated safety configurations including a DC fuse, a DC Surge Protective Device (SPD) for lightning protection, and either a DC circuit breaker or a DC load isolation switch to prevent electrical faults.
What types of solar panels are compatible with this product?
This combiner box is highly versatile and is suitable for single crystal silicon solar modules, polycrystalline silicon solar modules, as well as thin film solar modules.
What is the maximum DC voltage and input configurations supported?
It supports a maximum system DC voltage of 1000V DC and accommodates up to 15A input current per string. Depending on the model (PV1/1 to PV6/1), it supports anywhere from 1 to 6 input strings.
How is the combiner box installed and mounted?
It is designed for standard wall mounting. Installation is highly simplified to reduce system wiring and ensure convenient field connections.
