A generator string is disconnected from the device owing to a
faulty fuse. Check why it has tripped by measuring all DC
strings using a clip-on ammeter. - If there is no current flow in a
string, the associated DC fuse is faulty.
› Check the no-load voltage and dimensioning of the PV gener-
ator. Replace any damaged modules.
› Replace the PV fuse with a fuse of the same size and type.
