FAQs of DCDB Box:

Q: How is the DCDB box installed in a solar PV system?

A: The DCDB box is designed for wall mounting, typically positioned near the solar module array. Installation involves securing the enclosure using mounting brackets and connecting the input/output ports with pre-installed cable glands to the PV strings and inverter.

Q: What are the benefits of using a DCDB box with IP65 ingress protection?

A: IP65 ingress protection means the box is dust-tight and protected against water jets, making it suitable for outdoor environments. This ensures reliable operation and longevity of the protective components in various climatic conditions.

Q: When should the DCDB box be used within a solar installation?

A: This DCDB box should be used whenever independent string protection is required, particularly in systems where safe and organized distribution, overcurrent, and surge protection are necessary for the PV array.

Q: Where is this DCDB box most effectively utilized?

A: The box is ideal for solar PV projects in residential, commercial, or industrial settings across India, wherever string-level voltage and current protection is mandatory and harsh environmental factors are present.

Q: What is the process for maintaining the DCDB box?

A: Maintenance involves periodic visual inspection for any signs of wear or damage, checking fuse integrity, ensuring the busbar connections are secure, and confirming surge protection status. All parts are accessible via the front cover.

Q: How does the fuse and SPD arrangement protect my solar system?

A: The MC4/10x38mm fuses protect against overcurrent conditions, while the included Type II surge protection device guards the PV array and inverter from voltage surges caused by lightning or grid disturbances, thereby enhancing system safety.

Q: What are the usage limitations of the DCDB box?

A: The DCDB box supports a maximum system voltage of 1000 VDC and a rated current of 16A. It is suitable for string-level protection in solar PV systems with these parameters and is not designed for AC distribution or applications exceeding these ratings.
