Parameter Description
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.
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.
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.
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.
Reactive power compensation
(cosφ-P) trigger voltage (%)
Species the voltage threshold for triggering reactive power
compensation based on the cosφ-P curve.
Reactive power compensation
(cosφ-P) exit voltage (%)
Species the voltage threshold for exiting reactive power
compensation based on the cosφ-P curve.
