For solar module grounding at the negative pole Fronius recommends following fuse:
nominal current 1A / 600 V, fuse size 10 x 38 mm
IMPORTANT! Fuses for solar module grounding are not included with the inverter. If a so-
lar module grounding is required by the solar module manufacturer, a suitable fuse has to
be ordered separately.
Configuring the
inverter for
grounded solar
modules
The inverter's insulation monitoring must be deactivated when the solar modules are
grounded. In the Basic menu, the inverter must therefore be configured so that when the
grounding fuse trips, an error message is displayed or the inverter is switched off (accord-
ing to the country setup).
The access code 22742 must be entered to access the Basic menu.
