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.
