Reliable protection for PV systems with string inverters

More safety and efficiency for PV systems

Whereas the inverters were previously limited to an output voltage of AC 400 volts, the latest generation string inverters of the latest generation already provide 800 V AC. The higher voltage significantly reduces line losses and the overall efficiency of the system is improved. The protective devices such as fuses and switchgear must therefore be dimensioned for the higher voltage. For the reliable protection of the inverters at the AC 800 V voltage level EFEN offers harmonised protection components consisting of switchgear and NH fuse-links. As a result, there is a low power dissipation and a high rated breaking capacity.
