OFF due to abnormal
grounding
This function is used to
detect whether the
SUN2000 is properly
grounded before starting the
SUN2000, or to detect
whether the ground cable is
disconnected when the
SUN2000 is working. This
parameter is set to Enable
by default. For certain types
of power grids, if an
isolation transformer
connects to the output side
of the SUN2000, you need
to set OFF due to
abnormal grounding to
Disable after checking that
the SUN2000 is properly
grounded. Then the
SUN2000 can start
normally.
If you are not sure whether
the SUN2000 connects to
such a power grid, check
with your supplier or
Huawei technical support.
