Photovoltaic surge protection for residential installation

For low power PV applications, i.e. residences and small offi ces, it is necessary to consider surge protecting the AC output of the Inverter that connects directly into the electric power grid as well as the DC input side of the Inverter fed by the PV modules.

Surge protection for Off-grid site

Grid-isolated sites powered by solar panels are, due to their isolated location and exposure to lightning, especially prone to transient overvoltages.
