DCAC hermetic switchgear IP65 EMITER with DC surge arrester Noark 1000V type 2, 1 x MPPT / AC heating Noark type 2, 20A 3-phase EM-41N_DCAC

Safety and protection of photovoltaic installation

The EMITER hermetic DCAC distribution box with surge limiter is a comprehensive solution for protecting photovoltaic installations. It provides protection on both the DC and AC sides, minimizing the risk of damage caused by surges. The design is intended for reliability and durability, which translates into long-term protection of the PV system.

Construction and application

The distribution box housing, with an IP65 protection rating, guarantees tightness and resistance to external factors – dust and water jet. This allows the device to be mounted both indoors and outdoors. The distribution box is designed to handle one photovoltaic string and one MPPT (Maximum Power Point Tracking) input. The built-in Noark 1000V type 2 DC surge limiter protects the PV string from the effects of sudden voltage increases, and the Noark type 2 AC surge limiter with a current of 20A protects the AC part of the installation. This combination provides comprehensive protection of the entire system.

Advantages for the installer and end user

• Versatility: The distribution box works with photovoltaic modules, microinverters and inverters equipped with an MPPT input.
• Resistance to weather conditions: The hermetic IP65 housing allows outdoor mounting without fear of damage caused by moisture or dust.
• Effective protection: DC and AC surge limiters minimize the risk of installation failures caused by surges, which translates into savings and increased system life.
• Simple installation: The compact design makes installation and integration with existing infrastructure easier.
• Safety: Surge protection is a key element ensuring safe operation of the photovoltaic installation.

It is worth remembering that the distribution box is adapted to single-phase AC systems with a maximum current of the limiter of 20A. For three-phase installations, dedicated solutions with appropriate parameters should be used. The selection of the appropriate distribution box should take into account the DC voltage (up to 1000V) and the current of the limiters, to ensure optimal protection of the photovoltaic system.
