Grid parameters
Specifications
Description
Value Range (Vn: rated
voltage, Fn: rated frequency)
Grid code
Set this parameter based on the grid code of the
country or region where the SUN2000 is used
and the SUN2000 application scenario.
N/A
Isolation
Specifies the working mode of the SUN2000
according to the grounding status at the DC side
and the connection status to the grid.
Input ungrounded, without TF
Input ungrounded, with TF
Auto start upon grid
recovery
Specifies whether to allow the SUN2000 to
automatically start after the power grid recovers.
Disable
Enable
On-grid recovery
time (s)
Specifies the waiting time for SUN2000 restart
after the power grid recovers.
[0, 7200]
Grid reconnection
voltage upper limit
(V)
The standards of certain countries and regions
require that the SUN2000 must not export power
to the power grid again when the grid voltage
exceeds the value of
Grid reconnection voltage
upper limit
after the SUN2000 shuts down due
to a fault.
[100%Vn, 136%Vn]
Grid reconnection
voltage lower limit
(V)
The standards of certain countries and regions
require that the SUN2000 must not export power
to the power grid again when the grid voltage is
below the value of
Grid reconnection voltage
lower limit
after the SUN2000 shuts down due
to a fault.
[45%Vn, 95%Vn]
Grid reconnection
frequency upper
limit (Hz)
The standards of certain countries and regions
require that the SUN2000 must not export power
to the power grid again when the grid frequency
exceeds the value of
Grid reconnection
frequency upper limit
after the SUN2000 shuts
down due to a fault.
[100%Fn, 112%Fn]
Grid reconnection
frequency lower
limit (Hz)
The standards of certain countries and regions
require that the SUN2000 must not export power
to the power grid again when the grid frequency
is below the value of
Grid reconnection
frequency lower limit
after the SUN2000 shuts
down due to a fault.
[85%Fn, 100%Fn]
Reactive power
compensation
(cosφ-P) trigger
voltage (%)
Specifies the voltage threshold for triggering
reactive power compensation based on the
cosφ-P curve.
[100, 110]
Reactive power
compensation
(cosφ-P) exit voltage
(%)
Specifies the voltage threshold for exiting
reactive power compensation based on the
cosφ-P curve.
