DCAC hermetic distribution box IP65 EMITER with surge protection device DC Noark 1000V type 2, 1 x MPPT, 10A 1-pole EM-123N_DCAC

Safety and Protection in Photovoltaic Installations

The EMITER hermetic DCAC distribution box with Noark surge protectors is a key element ensuring the safe and reliable operation of a photovoltaic installation. Using this distribution box minimizes the risk of damage caused by overvoltages on both the DC and AC sides. This is particularly important in the event of sudden voltage spikes, such as lightning strikes, which can lead to serious failures and downtime in energy production.

The distribution box is designed to operate with installations up to 1000V DC and protects a single photovoltaic string. The built-in Noark type 2 DC surge protector effectively protects against the effects of overvoltage, and an additional Noark AC surge protector (10A, 1-phase) protects the AC circuit. This ensures that both DC components (panels, cabling) and AC components (inverter, power grid) are adequately protected.

Construction and Application

The distribution box housing is made of materials resistant to weather conditions and has an IP65 protection rating. This means complete protection against dust and water jets, allowing the device to be mounted outdoors, near the photovoltaic panels. Compact dimensions facilitate installation and integration with existing infrastructure.

The distribution box serves as a connection point between the PV string and the inverter, providing a safe and organized connection of the cables. It is dedicated to cooperation with inverters equipped with MPPT (Maximum Power Point Tracking) – a technology that allows for maximum utilization of solar energy. Mounting the distribution box near the panels shortens the length of the DC cables, which minimizes energy losses and improves the efficiency of the entire system.

For the Installer and End User

For the installer, the EMITER distribution box is a ready-made solution that simplifies installation and ensures compliance with applicable safety standards. The compact design and intuitive connection layout speed up the installation process and minimize the risk of errors. In addition, the use of high-quality Noark components guarantees the reliability and long life of the device.

For the end user, the distribution box means above all peace of mind – knowing that their photovoltaic installation is properly protected against the effects of overvoltage and failures. The hermetic housing protects the components from external factors, which translates into a longer system life and lower operating costs.
