Description
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).
Specifies the threshold for triggering
HVRT.
The threshold settings should meet the
local grid standard.
During HVRT, the inverter needs to
generate reactive power to support the
power grid. This parameter is used to
set the reactive power generated by the
inverter.
Specifies whether to shield the
undervoltage protection function
during LVRT or HVRT.
Specifies whether to enable the active
islanding protection function.
The standards of certain countries and
regions require that the SUN2000
should prevent the grid voltage from
rising by delivering reactive power and
decreasing active power when the
output voltage exceeds a certain value.
The standards of certain countries and
regions require that the SUN2000 must
generate a certain amount of reactive
power when the output voltage exceeds
a certain value.
The standards of certain countries and
regions require that the active power of
the SUN2000 be derated according to a
certain gradient when the output
voltage exceeds a certain value.
Specifies the time for the power to
gradually increase when the SUN2000
restarts after the power grid recovers.

Remarks
-
This parameter is displayed when
HVRT is set to Enable.
For example, if this parameter is
set to 2, the reactive power
generated by the inverter is 20%
of the rated power when the AC
voltage drops by 10% during
LVRT.
This parameter is displayed when
LVRT or HVRT is set to
Enable.
-
-

This parameter is displayed
when Voltage rise
suppression is set to Enable.
 The value of Voltage rise
suppression active derating
point must be greater than
that of Voltage rise
suppression reactive
adjustment point.
