ML System is a Polish company technology specializing in the production of innovative building-integrated photovoltaic solutions (BIPV), including photovoltaic switchboards, which are a key element securing and monitoring photovoltaic systems.
ML SYSTEM DEHN switchgear T1+2 DC 1 chain is an advanced set of devices with T1+T2 overvoltage protection on the DC side, designed for indoor applications. This is an ideal solution for installations with one inverter MPP Tracker and up to two strings.
This switchgear is equipped with a T1+T2 surge arrester, which ensures safe and optimal operation of the photovoltaic system. This is an ideal solution for indoor installations where surge protection is crucial.
Distribution board ML SYSTEM DEHN T1+2DC 1 chain offers many advantages. First, it provides excellent surge protection, which is crucial for the safe and efficient operation of a photovoltaic system. Secondly, its use indoors makes it resistant to weather conditions. Thirdly, thanks to the use of strip connectors, installation and servicing of the device are simple and convenient. Finally, thanks to the use of high-quality materials, such as RAL 7035 polystyrene for the housing and polycarbonate for the window, the switchgear is durable and resistant to damage.
