DC/AC Distribution Box – Safety and Protection for Photovoltaic Installations

The EMITER DC/AC connection box, with an IP65 protection rating, is a key element of every modern photovoltaic installation. It not only provides a safe and organized connection of PV modules to the inverter but, above all, comprehensive protection against the effects of surges, both on the direct current (DC) and alternating current (AC) sides. The design of the distribution box has been carefully thought out to facilitate installation and integration with the system, minimizing the risk of failure and extending the life of the entire installation.

Construction and Application

The distribution box is designed to work with photovoltaic installations equipped with two PV strings and two independent MPPT (Maximum Power Point Tracking) inputs in the inverter. The hermetic housing with IP65 class guarantees protection against external factors – dust, moisture, and even a direct stream of water – making it ideal for mounting outdoors or in rooms with high humidity. Thanks to this solution, installers can place the distribution box in a location optimal in terms of cabling and service access.

Inside the distribution box are high-quality surge arrestors from the Dehn brand. Type 2 arrestors are used on the DC side, designed to protect against impulse voltages with a working voltage of up to 1000V. On the AC side, there is a type 2 surge arrester with parameters of 25A 3-F, which protects against the effects of disturbances in the power grid. This configuration provides complete protection for sensitive components of the photovoltaic installation – PV modules, inverter, and receiving devices.

Advantages for the installer and end user

• Comprehensive protection: Integrated Dehn surge arrestors provide effective protection against damage caused by atmospheric surges or disturbances in the grid.
• Hermetic IP65 housing: Guarantees safe operation in harsh weather conditions and minimizes the risk of corrosion.
• Simplified installation: The distribution box has been designed with easy and quick installation in mind, which translates into saving time and labor costs.
• Performance optimization: The ability to connect two independent PV strings to two MPPT inputs allows for maximum utilization of the potential of the photovoltaic installation.
• Safety of use: Compliance with safety standards and the CE certificate provide peace of mind for the end user.
• Cost reduction: Eliminating the need for additional enclosures for surge arrestors and simplifying the cabling translate into lower investment costs.
• Durability and reliability: The use of high-quality components and a solid construction ensure long-term and trouble-free operation of the distribution box.

The EMITER distribution box is an investment in the safety and efficiency of your photovoltaic installation – a solution that will be appreciated by both professional installers and end users looking for a reliable and durable product.
