Connection box SZR hermetic IP65 EMITER for Huawei M1 inverter EM-HWM1-SZR

Connection box for Huawei inverter – safety and functionality

This hermetic connection box, designed by EMITER, is dedicated to working with Huawei M1 inverters. It provides a safe and reliable connection of the photovoltaic installation to the power grid, and its sealed housing (IP65) protects against weather conditions and external interference. It is a key element of the PV system, ensuring optimal operation and long-term protection of components.

Construction and application

The connection box is made of durable materials, which guarantees its durability even in harsh operating conditions. Its compact dimensions (319 mm wide, 384 mm high and 144 mm deep) allow for easy installation in various locations. It is designed for three-phase systems and allows connection of four PV strings with four MPPT points. Inside there is a DC surge arrester Dehn 1000V type 1+2, which effectively protects against the effects of lightning strikes and overvoltages in the grid.
