Overview of the typical components and structure of EPG series 1500V DC Photovoltaic Combiner Box:

1. Casing: Constructed using stainless material and featuring an IP65 anti-pollution rating, the casing provides physical protection to the internal components and ensures system safety.

 

2. ED250z 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 enables safe maintenance, inspection, and repair by cutting off the current flow. In case of emergencies or system faults, the ED250z DC disconnect switch allows for quick and immediate shutdown of the PV system, preventing further damage and ensuring personnel safety.

 

3. DC fuse holders and DC fuses for overcurrent and short circuit protection: The EPG series 1500V DC Photovoltaic Combiner Box incorporates ER63(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.

 

4. EPD DC Surge Protection Devices: In areas prone to lightning strikes or grid disturbances, the EPG series 1500V DC Photovoltaic Combiner Box includes DC EPD surge protection devices. These devices divert and suppress high voltage surges, safeguarding the solar panels and other components from potential damage.

 

5. MC4 connectors: The EPG series 1500V DC Photovoltaic Combiner Box features MC4 multiple input and output connectors, facilitating efficient connection between the output cables from individual solar panels and the input cables of PV inverters.

 

6. Grounding Connections: The EPG series 1500V DC Photovoltaic Combiner Box provides terminals for connecting grounding conductors, ensuring proper grounding for the system.

 

7. Cable accessories: Various 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 arrangement helps maintain a tidy and systematic wiring layout, reduces the risk of cable damage, and facilitates maintenance and troubleshooting efforts.
