When we are looking at protecting an installation against over voltage, we have to give some consideration to external cables entering the building. PV installations will come in to this bracket. Surge protection device’s for PV systems are to protect the inverter and the fixed installation, therefore PV SPD’s should be installed on the DC side of the PV system, before the inverter. These will always be Type 2 devices, unless the building has an external lightning protection system and the correct separation distance to BSEN 62305-3 has not been maintained, where you would install a Type 1 SPD.
