Solar Power Project Components: NUCLEUS ACDB, DCDB, and AJB Solutions for Distributors

Sinesan Technologies Pvt. Ltd., established in 2013 in South Rajasthan, has rapidly emerged as a trusted name in the power products industry. With the NUCLEUS brand, the company specializes in Online UPS, Servo Voltage Stabilizers, Solar Off-grid Inverters, and a range of solar project components including ACDB, DCDB, and AJB.

The Indian solar energy sector has witnessed exponential growth in the last decade. North India, in particular, is experiencing a surge in utility-scale and commercial solar projects. For distributors and wholesalers, procuring high-quality solar components in bulk not only ensures competitive pricing but also strengthens their position in the growing solar market.

Understanding Solar Power Project Components

Solar projects rely on several critical components to ensure efficiency, reliability, and safety. Among them, ACDB, DCDB, and AJB play pivotal roles:

  • ACDB (AC Distribution Box): ACDBs distribute alternating current from the inverter to various load points. They protect the system from electrical faults and improve overall safety.
  • DCDB (DC Distribution Box): DCDBs collect direct current from solar panels and route it efficiently to inverters. They include fuses and surge protection devices, ensuring system reliability.
  • AJB (Array Junction Box): AJBs connect multiple solar panels in an array and facilitate wiring to the DCDB. They provide surge protection and streamline system installation.
