Photovoltaic systems are composed by photovoltaic panels, cables, fuses, overvoltage arresters and power inverter. Photovoltaic panels utilise the power of sun light to converters photons to DC current. Electricity generated by solar panels is then fed into a power inverter that converts DC current to AC current. gPV fuse has been developed to protect against overcurrent. ETITEC B, C-PV series of over voltage surge protective devices has been developed to protect against direct and indirect lightning discharges and is intended to protect photovoltaic systems. The circuit topology consists of two varistors stages each protected by a thermal disconnection device.
