Emiter EM-102_DCAC Hermetic Combiner Box (DC/AC, 2xMPPT, 20 A)

The Emiter EM-102_DCAC hermetic combiner box is a ready-to-connect surface-mounted solution designed for photovoltaic systems. The box is equipped with Dehn type 2 DC and AC surge arresters and a 3-phase 20 A miniature circuit breaker.

The Emiter EM-102_DCAC junction box is ideal for photovoltaic systems with or without an isolated lightning protection system. The transparent-door design is suitable for surface mounting and ensures a high IP65 protection rating. Inside, a 24-module PHS 24T enclosure made of halogen-free plastic is used. The combiner box supports two module strings on two independent MPPT inputs using panel-mounted MC4 connectors.
