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. Example of a photovoltaic surge protection installation Selection of surge protectors On this table you will find the surge protection solution for residential PV installations.
