Issue 12 (2019-01-15)
Description
The Japanese standard
requires that the inverter
should derate the active
power to prevent the grid
voltage from rising when
the output voltage
exceeds a certain value.
Description
When the power grid
voltage is abnormally low
for a short time, the
inverter cannot disconnect
from the power grid
immediately and has to
work for some time. This is
called LVRT.
Specifies the threshold for
triggering LVRT.

Remarks
This parameter is set to
Enable by default if
the German
BDEW-MV grid code
is selected.
This parameter is
displayed when LVRT
is set to Enable.
In 1000 V inverters,
the
SUN2000-(8KTL-28K
TL) does not support
this parameter.
Vn represents the rated
voltage.
