Surge Trap for advanced safer photovoltaic installations
Fault currents coming from solar cells are too much low to blow disconnecting fuse in series with SPDs (Surge Protective Devices).
Most of users don't install this kind of fuses. Standard SPDs are unable to disconnect by themselves then their temperature rises leading sometimes to fire.
Use breakers is not a solution. This component operates inconveniently letting the user without any protection against overvoltages.
Using SPDs with built-in disconnecting device is the unique reliable solution then avoiding a lot of troubles to installers and users of PV power generation systems.
