DC Protection Box for Solis S6-EH3P40K-H/S6-EH3P50K-H Three-Phase Hybrid Inverters -

The SW4018 DC protection box is designed to secure photovoltaic installations equipped with Solis S6 three-phase hybrid inverters (models EH3P40K-H and EH3P50K-H). Intended for professional photovoltaic installers and integrators, this box protects the direct current of the solar panels against overcurrents and overvoltages, thus guaranteeing the safety, reliability, and optimal performance of hybrid systems in high-power residential, commercial, or industrial projects. The SW4018 incorporates a high-quality DC surge arrester, ensuring effective protection against overvoltages caused by lightning and electrical disturbances. Its modular and compact design facilitates integration into electrical cabinets and allows for easy access for maintenance. Compatible with the 40 kW and 50 kW Solis S6 hybrid models, it offers a safe and standardized installation for high-power photovoltaic systems. The robust components of the enclosure are designed to withstand climatic and electrical stresses, ensuring maximum equipment longevity. Using this enclosure offers tangible benefits to installers. It allows for the rapid securing of hybrid inverters, limits the risk of failure or damage to the DC network, and ensures stable and continuous solar energy production. Thanks to the integrated DC surge protector, the SW4018 protects sensitive equipment and reduces service interruptions, while simplifying maintenance through clear access to the protection devices. For commercial, industrial, and service sector projects, the SW4018 effectively secures 40 kW and 50 kW Solis S6 hybrid inverters, guaranteeing power continuity and protecting equipment against surges. Its robustness, universal compatibility with Solis S6 hybrid inverters, and integrated surge protector make it an essential component for photovoltaic installers seeking to combine performance, safety, and durability in all their installations.
