Description
The standards of certain
countries and regions
require that the active
power of the inverter be
derated according to a
certain gradient when the
output voltage exceeds a
certain value.
The standards of certain
countries and regions
require that the inverter
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 inverter be
derated according to a
certain gradient when the
output voltage exceeds a
certain value.
The inverter triggers
protection when the power
grid frequency changes too
fast.
Specifies the frequency
change rate protection
threshold.
Specifies the frequency
change rate protection
duration.
Specifies the time for the
power to gradually increase
when the inverter restarts
after the power grid
recovers.
