DCAC hermetic switchboard IP65 EMITER with DC surge arrester Noark 1000V type 1+2, 2 x MPPT / AC arrester Noark type 1+2, 20A 3-phase EM-214N_DCAC

DCAC Hermetic Distribution Box – Protection and Optimization of Photovoltaic Installation

This hermetic DCAC distribution box, manufactured by EMITER, is a key element of every modern photovoltaic installation. It provides not only safe energy distribution but also comprehensive protection against overvoltage, which translates to the reliability and longevity of the entire system. It is an ideal solution for both installers and end-users who value safety and efficiency.

Safety and protection in one

The distribution box is equipped with DC surge arresters Noark 1000V type 1+2 and AC surge arresters Noark type 1+2 with a current of 20A (3-phase). This means double protection – both on the DC and AC side of the installation. These arresters effectively minimize the risk of damage caused by sudden voltage surges that can occur during a thunderstorm or due to disturbances in the power grid. This protects not only sensitive components of the photovoltaic installation, such as inverters and panels, but also devices connected to the electrical network in the building.

Construction and application

The enclosure of the distribution box is made of a durable material and has an IP65 protection rating. This means complete protection against dust and water jets – allowing installation both indoors and outdoors, exposed to changing weather conditions. The distribution box is adapted to handle two PV strings and two MPPTs (Maximum Power Point Tracking), which allows for optimization of the efficiency of photovoltaic panels. The design allows for easy installation and access to individual elements, which facilitates maintenance and servicing.

Key product features:

• Hermetic IP65 enclosure: provides protection against external factors, enabling installation in various environmental conditions.
