The OBO generator connection box is a highly developed accessory for photovoltaic systems, specifically designed for connecting two PV strings. It provides a reliable solution for DC protection of the inverter and ensures safe and efficient energy transfer. The box is equipped with a plug-in varistor surge protector and features a disconnection device in a fault-resistant Y-circuit according to VDE 0100-712. With a low DC protection level of under 4.0 kV and a maximum operating voltage of 1000 V DC, this generator connection box is suitable for demanding applications. The polycarbonate housing is UV-resistant and offers an IP66 protection rating, making it ideal for outdoor use. The connection box comes with a cable gland set and a pressure equalization element to ensure optimal functionality. In special conditions that may lead to condensation, additional measures may be necessary.
