Photovoltaic Application: Protection of Cells & Inverter DC Side

Providing power with photovoltaic solar panels is tremendously interesting in the context of renewable energy sources. Because of their exposition, frequently in isolated sites, and the extended surface of photovoltaic systems, lightning strikes are a major component in the risk to be assumed, both for the direct effect of lightning on the structures, and of the surge overvoltages on the installation. The lightning group of ABB has developed a specific DIN Rail product to protect the DC side of cells and inverters against surge in power plant or residential application.
