DC/AC Hermetic Distribution Box – Safety and Functionality for Photovoltaic Installations

This hermetic distribution box from EMITER, equipped with DC and AC surge arresters, provides a comprehensive solution for connecting photovoltaic installations. Designed for reliability and ease of use, it effectively protects against the effects of surges, both on the direct current (DC) and alternating current (AC) sides. It is a key element of any modern PV installation, guaranteeing its long-term and safe operation.

Construction and Application

The distribution box is designed for mounting a single string of photovoltaic panels with one MPPT controller. Inside, there are components providing surge protection – a Dehn 1000V type 2 DC surge arrester and a type 2 AC surge arrester. Additionally, a three-phase 16A overcurrent switch is installed, which protects the circuit against overload and short circuit. The ready-to-connect design with MC4 connectors simplifies and speeds up installation. Thanks to the IP65 protection rating, the distribution box can be used both indoors and outdoors without fear of adverse weather conditions.

Advantages and Benefits

• Comprehensive protection: Protection against DC and AC surges ensures the safety of the entire photovoltaic installation and connected devices.
• Ready for installation: MC4 connectors and a compact design minimize installation time.
• Durability and reliability: The hermetic housing with an IP65 protection rating guarantees resistance to moisture, dust and other external factors.
• Safety of use: A 16A overcurrent switch protects against overload and short circuit, ensuring safe system operation.
• Versatility: Can be used in both grounded and isolated installations.
• Compliance with standards: The components of the distribution box meet the required safety standards.
• MPPT performance optimization: The design allows connecting one string of panels to one MPPT controller, enabling efficient use of solar energy.
• Easy identification: Transparent doors facilitate visual inspection of the internal components without opening the housing.

The EMITER distribution box is an investment in the long-term and safe operation of your photovoltaic installation – regardless of whether you are a professional installer or an end user.
