Description
Adjusts the active power output of the
SUN2000 to a percentage.
In some specific application scenarios,
a power grid company requires that
the SUN2000 can perform reactive
power compensation at night to ensure
that the power factor of the local
power grid meets requirements.
Adjusts the SUN2000 power factor.
Adjusts the SUN2000 output reactive
power.
If Reactive power output at night is
enabled, no PV input exists, and no
remote scheduling instruction is
delivered, the SUN2000 responds to
this command.
If this parameter is enabled, the active
power of the inverter will be derated
according to a certain slope when the
grid frequency exceeds the value that
triggers overfrequency derating.
The standards of certain countries and
regions require that the output active
power of the SUN2000 be derated
when the grid frequency exceeds a
certain value.
Specifies the frequency threshold for
exiting overfrequency derating.
Specifies the frequency threshold for
cutting off overfrequency derating.
Specifies the power threshold for
cutting off overfrequency derating.
Specifies the power recovery gradient
for overfrequency derating.
