We specialize in providing accessories for photovoltaic systems, including PV combiner boxes, fiberglass plastic enclosures, DC fuses, solar connectors, and more.
Our photovoltaic accessories are mainly utilized in the solar energy sector, catering to solar power project contractors, manufacturers of photovoltaic distribution equipment, as well as traders in the field.
We have more than 20 years of experience in manufacturing photovoltaic distribution products.
Standard specifications are available for plastic enclosures, photovoltaic fuses, and solar connectors. On the other hand, AC/DC combiner boxes are customized based on distribution designs.
Currently, we ship directly from our Chinese factory to customers, saving significant intermediary costs. In the future, we will have overseas companies or agents under direct management of the Chinese headquarters.
Our products meet industry standards like IEC60947-3 and AS60947-3 for solar energy. We’re ISO9001-2015 certified and hold international certifications like TUV and CE. Our product quality adheres rigorously to ISO quality management standards.
We primarily focus on the research and production of PV combiner boxes and related components. With a strong capability for in-house production (self-production rate above 85%), we ensure robust quality control and reliable bulk supply.

The solar combiner box is ideally placed between the solar inverter and the modules. This type of box requires very little maintenance, although regular maintenance is still recommended, so as to ensure that loose connections can be identified before any major disruptions occur.
Do solar panels have to be equipped with a combiner box?
For projects with only two or three strings of panels (like regular homes), a combiner box isn't necessary; instead, you may connect the strings directly to the inverter. Combiner boxes are only needed for larger projects, typically involving 4 to 4,000 strings of panels.
What’s the difference between DC and AC combiner boxes?
DC combiner boxes can handle multiple inputs and outputs. The inputs are determined by the number of photovoltaic strings and panels, while the outputs depend on the number of inverters. On the other hand, AC combiner boxes have one input and one output. The purpose of a combiner box is to gather electric current.
What is the primary purpose of a DC combiner box?
PV combiner box is a distribution box equipped with DC circuit breakers. Its main purpose is to consolidate multiple DC inputs from panels in the system into a single DC output. Depending on the system type, this output is then connected to a charge controller or an inverter.
What is a photovoltaic fuse?
Photovoltaic fuses, solar PV fuses, meltable PV fuses, and solar panel fuses are all the same specialized kind of fuse used in a photovoltaic (PV) or solar power generation system. The size of solar panel fuses is determined by various voltage, rating, and current specifications.
