The Alder A83 gPV (Photovoltaic) fuse series has been speciﬁcally designed for the protection of (PV) systems. These fuses can safely protect PV string modules, conductors and inverters from reverse-overcurrent and overcurrent conditions.
As PV systems have grown in size, so have the corresponding voltage requirements. This increase in system voltage has typically been intended to minimize power loss associated with long conductor runs. A83 gPV has up to 1100 VDC braking capacity.
