Description
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.
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.
