Importance of Combiner Box

Many people who have not paid much attention to the combiner box may think that the combiner box, which only occupies one or two cents in the cost of the power station, accounts for a small proportion of the investment in the power station, and it is just a switch and lightning protection fuse assembly, which has no technical content or so important. But in fact, it may be this little thing that, if treated badly, will cause a big headache for the power station, cause a lot of shortages, affect power generation, and even affect the personal safety of operation and maintenance personnel. Today, the Combiner Box Manufacturer will talk to you about the importance of the combiner box

Combiner Box

First of all, although the combiner box is small, 100% of the power generation capacity of the power station must go from the combiner box.

The investment of the combiner box in the entire power station accounts for less than 1%, but 100% of the power generation capacity of the power station comes from the combiner box. Any failure of a combiner box will directly affect the power generation.

We know that the efficiency of inverters and components has been developed to the extreme, and it is difficult to increase the power generation by 1%. But as long as a combiner box fails, the power generation of a square array will be lost. This shows the high importance of the combiner box in influencing the power generation.

Second, there are a large number of combiner boxes, and any small problem may be enlarged hundreds or thousands of times.

Taking a 100MW power station as an example, the number of standard DC1000V16 combiner boxes is about 1200, and the number of standard DC1500V24 combiner boxes is about 460.

Such a large number of equipment, if there is a little defect in the design or process technology, such as poor selection of components, such as rust or water leakage in the chassis, such as insufficient safety distance, too many connection points, and unfastened screws, etc. These problems will expand hundreds to thousands of times and are difficult to deal with.

Third, the equipment is scattered and maintenance is not easy

The Combiner Box are distributed in every corner of the photovoltaic area, which may be on a steep mountain slope, or in a depth of one or two meters. Especially for fish ponds or water surface projects that use pipe piles, two people need to peg the boat to stabilize the hull during maintenance, and then one person can climb a ladder to operate, which is very difficult to operate.

Fourth, the manufacturers are uneven and the quality varies

When the combiner box market is growing on a large scale, many manufacturers have begun to make combiner boxes. Maybe switch factories are doing it, maybe lightning arrester factories are doing it, maybe even sheet metal factories are doing it, and the quality is uneven. Nowadays, although only a few manufacturers have settled down and continue to produce after being eliminated and screened by the industry, professional combiner box manufacturers with major brands should still be selected. The pain they have experienced can help users of the combiner box avoid many detours and buy safer and more reliable combiner box products.

Therefore, although the combiner box is only a product of one or two cents in the power station, its importance cannot be ignored. Choosing a good product plays a very important role in subsequent maintenance and increasing power generation.
