Notes regarding the solar module ground in the in-
verter
General remarks
Some manufacturers of solar modules sti-
pulate that the modules must be grounded.
Fuse holder for solar module ground on the negative
pole
Inside the inverter is a means for grounding
solar modules to the negative pole via a fu-
se.
The fuse holder for grounding the solar mo-
dules is located on the rear of the inverter.
The inverter can also be operated with solar
modules that need to be grounded to the
positive pole.
IMPORTANT! The fuse in the inverter is not
used for grounding the solar modules to the
positive pole; this has to take place outside
the inverter.
