DC connection distribution box, hermetic IP65 EMITER with DC surge arrester Dehn 1000V type 1+2, 6x PV string, 6x MPPT EM-654_DC

Safety and functionality in photovoltaic installations

This hermetic DC connection box from EMITER, designed to operate in harsh weather conditions (IP65), is a key element of every professional photovoltaic installation. The use of a Dehn 1000V type 1+2 surge arrester guarantees protection against the effects of lightning strikes and overvoltages, which translates to system reliability and long life. The box is designed for optimal connection of six photovoltaic panel strings and six MPPT controllers, providing installation flexibility and scalability.

Construction and protection

The housing with IP65 protection effectively protects internal components from moisture, dust and other external factors. This solution is particularly important in installations exposed to direct weather conditions. The built-in Dehn surge arrester, compliant with 1000V type 1+2 standard, is an additional level of protection that minimizes the risk of damage caused by sudden voltage spikes. This arrester reacts quickly to overvoltages, dissipating excess energy to ground and protecting sensitive installation elements – inverters, charge controllers and the photovoltaic panels themselves.

Practical application and installation

The EM-654_DC box is ideal for both photovoltaic system installers and end-users who value safety and reliability. It allows central connection and distribution of energy from photovoltaic panels, and also provides easy access to measurement points. Compact dimensions and a hermetic housing facilitate mounting in various locations – on a wall or a pole. Six dedicated outputs for PV strings and six outputs for MPPT controllers allow for precise adaptation to the specifics of a given installation.
