SecSun AC/DC photovoltaic box for 2 independent strings 1000VDC three-phase – 10kW.

The unicobox DC/AC electrical panel for 2 independent 1000VDC three-phase strings represents an advanced solution designed to ensure the protection and complete management of three-phase photovoltaic systems. The system allows for separate management of the strings, improving the control and reliability of the system.

On the DC side, the panel is equipped with 2 x 2P fuse disconnectors with 16A-1000VDC fuses, ensuring effective protection against overcurrents. There are also 2 x 600VDC surge arresters, protecting the system from overvoltage, and 2 x 16A 1000VDC load break switches to guarantee safe circuit interruption.

On the AC side, the unit incorporates a residual current device (RCD) with overcurrent protection, 4x20A 6kA – 300mA Class A, which protects the system from overloads and earth faults. This protection is completed by a Class II three-phase surge arrester with an Imax of 20kA.

The unit has an IP65 Class II protection rating, making it suitable for outdoor installations. Segregation between DC and AC is also provided, ensuring safe circuit separation.

With dimensions of 340 × 622 × 161 mm, it offers a robust and reliable solution, easily installable.

The product is identified by the code UBT1102-1 and it complies with standard CEI EN 61439-1/2.
