The EPC Series 1000V DC PV Combiner Box is a crucial component in a PV system that plays a vital role in consolidating, protecting, and monitoring the DC power generated by solar panels. Its primary function is to ensure the efficient and safe operation of the solar energy system.

 

One of the key features of the EPC Series1000V DC PV Combiner Box is its compliance with safety standards and electrical codes specific to PV systems. It meets the necessary regulations related to over current and short circuit protection, grounding, and system isolation. By adhering to these standards, the combiner box enhances the safety and reliability of the entire PV installation.

 

Furthermore, the design and manufacturing of the EPC Series1000V DC PV Combiner Box prioritize compliance with relevant international standards and certifications. For instance, it conforms to IEC 61439, which pertains to low-voltage switchgear and controlgear assemblies. Additionally, it meets the requirements of IEC 62446, which focuses on PV system documentation and commissioning. These certifications ensure that the combiner box meets the necessary quality and safety standards for reliable performance in PV systems.

 

 

Overview of the typical components and structure of EPC Series1000V DC PV Combiner Box:

1. Enclosure: It is made by V0 class fire proof PC plastic material, with IP65 anti pollution level. The enclosure provides physical protection to the internal components and ensures the safety of the system.

 

2. EA80z or EA63z DC MCB, is used to provide a means of isolating or disconnecting the DC power generated by the solar panels from the rest of the PV system, it also provides the over current and short circuit protection. It allows for safe maintenance, inspection, and repair of the system by cutting off the flow of current.In case of emergencies or system faults, WEAG DC MCB allows for quick and immediate shutdown of the PV system. This can help prevent further damage to the system and ensure the safety of personnel during maintenance or emergency situations.

 

3. EPD DC Surge Protection Devices: In areas prone to lightning strikes or grid disturbances, EPC Series1000V DC PV Combiner Box includes DC EPD surge protection devices. It helps divert and suppress high voltage surges, protecting the solar panels and other components from damage.

 

4. MC4 terminals : EPC Series1000V DC PV Combiner Box has MC4 multiple input and output terminals which are used to connect with the output cables from individual solar panels and the input cables of the PV inverters efficiently.

 

5. Grounding Connections: EPC Series1000V DC PV Combiner Box provides terminals for grounding conductors.

 

6. Cable accessories: such as cable glands, cable ties, or cable trays, are incorporated into the combiner box to organize and secure the input and output cables. This helps maintain a neat and orderly wiring arrangement, reduces the risk of cable damage, and facilitates maintenance and troubleshooting.
