EPG series 1000V DC Photovoltaic Combiner Box is used in a PV system and facilitates the consolidation, protection, and monitoring of DC power generated by solar panels, ensuring efficient and safe operation of the solar energy system. It is designed to meet safety standards and electrical codes specific to PV systems. They ensure compliance with regulations related to over current and short circuit protection, grounding, and system isolation, thus enhancing the safety and reliability of the PV installation.

 

EPG series 1000V DC Photovoltaic Combiner Box are designed and manufactured to comply with relevant international standards and certifications, such as IEC 61439 for low-voltage switchgear and controlgear assemblies and IEC 62446 for PV system documentation and commissioning.

 

 

Overview of the typical components and structure of EPG series 1000V DC Photovoltaic Combiner Box:

Enclosure: The enclosure is constructed using V0 class fireproof PC plastic material, ensuring a high level of safety with its IP65 anti-pollution rating. It provides physical protection for the internal components and safeguards the entire system.

 

ED32z DC disconnect switch: This component serves as a means to isolate or disconnect the DC power generated by the solar panels from the rest of the PV system. It allows for safe maintenance, inspection, and repair by cutting off the current flow. In case of emergencies or system faults, the ED32z DC disconnect switch enables quick shutdown of the PV system, preventing further damage and ensuring personnel safety.

 

DC fuse holders and DC fuses for overcurrent and short circuit protection: The EPG series 1000V DC Photovoltaic Combiner Box incorporates ER32(s) fuse holders and fuses to protect against overcurrent situations. These devices are installed in series with the input cables or between the busbars and output cables. They interrupt the circuit in the event of a fault or excessive current, preventing damage to the PV system.

 

EPD DC Surge Protection Devices: To safeguard against lightning strikes or grid disturbances, the EPG series 1000V DC Photovoltaic Combiner Box includes DC EPD surge protection devices. These devices divert and suppress high voltage surges, protecting the solar panels and other components from potential damage.

 

MC4 connectors: The EPG series 1000V DC Photovoltaic Combiner Box features MC4 multiple input and output connectors, which efficiently connect the output cables from individual solar panels to the input cables of PV inverters.

 

Grounding Connections: The EPG series 1000V DC Photovoltaic Combiner Box provides terminals for connecting grounding conductors, ensuring proper grounding for the system.

 

Cable accessories: Additional components such as cable glands, cable ties, or cable trays are integrated into the combiner box to organize and secure the input and output cables. These accessories help maintain a tidy and organized wiring arrangement, reduce the risk of cable damage, and facilitate maintenance and troubleshooting tasks.
