SecSun light photovoltaic box AC/DC unicobox for 2 independent strings 1000VDC single-phase – 6kW.

The Unicobox DC/AC electrical panel for 2 independent strings is a solution designed to ensure the protection and complete management of single-phase photovoltaic systems up to 6 kW. Separate string management allows for better system control, increasing reliability and operational efficiency.

On the DC side, the panel is equipped with 2 x 2P disconnector fuse holders with 16A – 1000VDC fuses, ensuring protection against overcurrents. There are also 2 x 600VDC surge arresters for protection against voltage spikes and 2 x 16A – 600VDC load break switches, which allow for safe circuit interruption.

On the AC side, the cabinet integrates a 1P+N 32A – 6kA – 300mA Class A residual current circuit breaker with overcurrent protection, designed to protect the system from overloads and earth faults. A Class II single-phase surge protector with an Imax of 20kA completes the protection.

The unit has an IP65 Class II protection rating, making it suitable for outdoor installations, even in difficult environmental conditions, with segregation between the DC and AC sides for increased safety.

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

The product is identified by the code UBM2102L-1 and it complies with the regulations CEI EN 61439-1/2
