DC hermetic distribution box IP65 EMITER with DC surge arrester Dehn 1000V type 1+2, 3x MPPT EM-181_DC

DC Distribution Box – Safety and Efficiency for Photovoltaic Installations

The EMITER hermetic IP65 DC connection box, equipped with a DC surge arrester Dehn 1000V type 1+2, is a key element of every modern photovoltaic installation. It not only ensures a safe connection of panels to the inverter but also provides comprehensive protection against the effects of overvoltages that can damage sensitive system components. The design adapted to handle three strings of PV panels and three MPPT trackers allows for optimization of efficiency and flexible energy management.

Construction and Protection

The housing with IP65 protection rating guarantees complete tightness and resistance to weather conditions – dust, moisture or rain do not pose a threat to the internal components. This is particularly important when mounting outdoors. The built-in Dehn surge arrester, compliant with EN 50539-11, effectively protects the installation against sudden voltage surges caused by lightning strikes or other network disturbances. This arrester is characterized by high short-circuit strength (10 kA) and the ability to dissipate large current pulses (up to 40 kA), ensuring long-term system protection.

Functionality and Application

The distribution box is designed to operate with photovoltaic installations with a voltage of up to 1000 V DC and allows connection of three independent strings of PV panels. Support for three MPPT (Maximum Power Point Tracking) allows for independent optimization of each string, which translates into increased efficiency of the entire system. The installation of the distribution box is simple and intuitive, and its compact dimensions (144 x 259 x 325 mm) facilitate integration with existing infrastructure. It is ideal for both new installations and for modernizing existing photovoltaic systems.
