LVRT
reactive
power
compensation
power factor
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.
N/A
[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.
5
Reactive
power output
at night
In some specific
application scenarios, a
power grid company
requires that the SUN2000
can perform reactive power
compensation at night to
ensure that the power factor
of the local power grid
meets requirements.
N/A

Disable

Enable
This parameter is
configurable only
when Isolation is set to
Input ungrounded,
with a transformer.
6
HVRT
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 voltage
ride-through (HVRT).
N/A

7
HVRT
triggering
threshold
Specifies the threshold for
triggering the HVRT. The
threshold settings should
meet the local grid
standard.
V
