Description
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.
Specifies the threshold
for triggering LVRT.
Specifies whether to
shield the
undervoltage
protection function
during LVRT.
During LVRT, the
SUN2000 needs to
generate reactive
power to support the
power grid. This
parameter is used to
set the reactive power
generated by the
SUN2000.
When the power grid
voltage is abnormally
high for a short time,
the SUN2000 cannot
disconnect from the
power grid
immediately and has
to work for some time.
This is called high
