Surge arresters DC

Here you will find our DC surge arrester range.

The Mersen boxes are DC photovoltaic generator junction boxes for protecting the inverters against lightning and overvoltages in accordance with IEC/EN.

The boxes are pre-installed and are used in parallel with the inverters, mainly for 1000Vdc roof installations.

The DC surge arrester is equipped for PV systems and can be found under the „Surge arrester“ tab.
