SecSun AC/DC photovoltaic cabinet unicobox plus.

The single-box DC/AC switchgear for 2 strings in parallel three-phase - 10kW is an advanced solution designed to ensure the protection and monitoring of three-phase photovoltaic systems. This switchboard is designed to handle the entire DC and AC side protection. On the DC side, it includes two 2P fuse holders with 16A-1000VDC fuses, a 600VDC surge arrester, and a 32A 600VDC underload disconnector, ensuring optimal protection of the PV strings. On the AC side, it is equipped with a 4x20A 6kA - 300mA Class A thermal-magnetic circuit breaker with differential lock, which protects against overloads and ground faults, while the Class II Imax 20kA three-phase surge arrester defends the system against voltage peaks. The switchboard has an IP65 Class II protection rating, making it dust and water resistant, perfect for outdoor installations. Segregation between DC/AC is present, ensuring safe separation of circuits. With dimensions of 448 × 432 × 161 mm, it is compact and easy to install in tight spaces, while ensuring high reliability and safety. The switchboard complies with the CEI EN 61439-1/2 standard, attesting to its quality and compliance with safety regulations.
