The combiner box is an important part of the solar photovoltaic system. It is usually installed between the solar panel and the inverter. It is used to collect the current from multiple solar panels onto a cable and then deliver it to the inverter to make the transformation. Therefore, the combiner box can be regarded as an important node for power transmission in the solar power generation system.

The functions of combiner box

1. Collect current

The main function of the combiner box is to concentrate the output current of multiple solar panels into one cable, making it more convenient to collect current and save a lot of cable materials, manpower and material costs.

2. Protect electrical components

In the process of organizing current in solar panels, the size and shape of the current may be affected, leading to damage or short circuits, so a combiner box is needed to protect the electrical components and avoid this situation.

3. Enhance system reliability

Through the combiner box, the solar panels can work better and the reliability of the system is also enhanced, avoiding system failure or damage due to cable joints and other reasons.

The structure of the combiner box

Combiner boxes are usually made of high-strength protective materials and are waterproof, anti-corrosion and weather-resistant. It usually includes components such as fuses, arresters, DC power switches and monitoring devices to meet various requirements in solar power systems.

Regarding combiner box, which I have to mention is DCBess combiner box. It funnels electricity from the solar panels to an inverter and then to DC Bess’s battery system. The combiner box is suitable for DCBess Thermostatic household energy storage lithium battery system of all sizes and has the advantages of convenience and reliability. It is widely used in industrial and commercial buildings, residential communities, traffic lights, rural and remote areas, etc., making important 

contributions to people's lives and social development. This system comes with an automatic cooling system that extends battery life to more than 10 years and more than 6,000 cycles.
