DCAC hermetic switchboard IP65 EMITER with DC surge arrester Dehn 1000V type 1+2, 3 x MPPT / AC Noark type 1+2, 63A 3-phase EM-1291N_DCAC

DCAC Distribution Box – Comprehensive Protection for Photovoltaic Installations

The DCAC connection box in a hermetic IP65 housing is a ready-made solution for photovoltaic installations, providing effective protection against overvoltage and a safe connection to the grid. The design is intended for demanding operating conditions, guaranteeing reliability and long-term operation. It is an ideal choice for both professional installers and end-users looking for comprehensive protection of their investment.

Safety and functionality in one

A key element of the distribution box is the built-in overvoltage protection (SPD) on the DC side from Dehn, type 1+2, with a rated voltage of 1000V. This means protection against the effects of direct and indirect lightning strikes and sudden voltage surges, which is particularly important for photovoltaic installations exposed to variable weather conditions. Additionally, the distribution box is equipped with a Noark type 1+2 surge arrester AC (63A, 3-phase), which protects the AC side. A type A residual current device (RCD) (63A/300mA) provides an additional level of safety by detecting and interrupting circuits in the event of short circuits to earth.

Construction adapted to the needs of PV installations

The distribution box allows connection to three photovoltaic strings and works with three independent MPPT (Maximum Power Point Tracking) controllers. This configuration allows for optimization of energy conversion efficiency in solar systems. The hermetic housing with an IP65 degree of protection guarantees resistance to dust and moisture, allowing the distribution box to be mounted both indoors and outdoors – in places exposed to atmospheric conditions.

• Overvoltage protection: The use of Dehn and Noark arresters provides comprehensive protection against the effects of lightning strikes and voltage surges on the DC and AC sides.
• Safety of use: The built-in type A RCD protects against electric shock.
• Versatility: Possibility to connect three PV strings and cooperate with three MPPT controllers.
• Resistance to external conditions: Hermetic IP65 housing provides protection against dust and moisture.
• Easy installation: Compact design facilitates integration with the existing photovoltaic installation.
• Compliance with standards: The product has a CE marking confirming compliance with European safety standards.

The EMITER EM-1291N_DCAC distribution box is not only a protective element, but also a key component of a modern photovoltaic installation, ensuring its reliable operation and longevity.
