Emiter EM-382_DCAC DC/AC Combiner Box (IP65, 2 MPPT, 25 A)

The Emiter EM-382_DCAC combiner box is designed to protect 3-phase photovoltaic installations with two MPPTs. The IP65-rated device is ready to connect and features Dehn surge arresters and Noark switchgear.

The surface-mounted combiner box by Polish manufacturer Emiter is designed to protect grounded and isolated PV installations against short circuits, overloads, and lightning strikes. The design is based on a halogen-free PHS 24 T modular enclosure with an IP65 protection rating, ensuring safe outdoor installation. The integrated Stäubli MC4 panel receptacles allow for quick connection of two PV strings for two MPPTs. The device is UV-resistant and features a wide operating temperature range from -25°C to +60°C.
