About Photovoltaic Energy StorageIn this capacitor unit type an individual fuse, externally assembled between the capacitor unit and the capacitor bank fuse bus, protects each capacitor unit.
About Photovoltaic Energy StorageInternal fuses in capacitor units There are two types of fuses used for capacitors; internal and external. When the reactive power of a capacitor unit was only a few kvar, the most natural method to protect the capacitor was with an external fuse, since in the case of a breakdown the lost reactive power was small.
