Emiter EM-426_DC DC Combiner Box (4 MPPT, Type 1+2, IP65)

The Emiter EM-426_DC direct current combiner box is designed for surface mounting in photovoltaic installations. Housed in an IP65-rated PHS 12T enclosure, the box is ready for connecting 4 PV strings to 4 MPPT inputs using MC4 connectors.

The hermetic Emiter EM-426_DC combiner box is used to protect photovoltaic installations, including systems with or without isolated lightning protection. The product is based on a 12-module enclosure made of halogen-free plastic, equipped with a transparent door. Inside, four Dehn DCB YPV 1200 Type 1+2 DC surge arresters with operating state indicators are installed. The design ensures an IP65 protection rating and IK08 mechanical impact resistance.
