1 LVRT When the power grid
voltage is abnormally
low for a short time,
the SUN2000 cannot
disconnect from the
power grid
immediately and has
to work for some time.
This is called LVRT.
2 LVRT Specifies the threshold
threshold for triggering LVRT.
LVRT Specifies whether to

4 LVRT During LVRT, the
reactive SUN2000 needs to
power generate reactive
compensati power to support the
on power power grid. This
factor parameter is used to
set the reactive power
generated by the
SUN2000.

[0, 3] For example, if you
set LVRT reactive
power
compensation
power factor to 2,
the reactive current
generated by the
SUN2000 is 20%
of the rated current
when the AC
voltage drops by
10% during LVRT.
