Description
Specifies the active power
threshold in percentage.
Specifies the protection threshold
of the reactive power after
communication is interrupted,
including Q/S and power factor.
Specifies the Q/S threshold of the
reactive power.
● If multiple inverters are
cascaded, the Smart Dongle or
SmartLogger is connected, and
closed-loop scheduling is
enabled, set this parameter to
SDongle/SmartLogger.
● If there is only one inverter
and closed-loop scheduling is
enabled, set this parameter to
Inverter.
● If closed-loop scheduling is
disabled, retain the default
value.
The standards of certain countries
and regions require that when the
power grid frequency is lower
than the frequency threshold for
power raising, the device needs to
increase the active power output
to help increase the power grid
frequency. In this case, set this
parameter to Enable.
Specifies the power recovery rate
of underfrequency-caused raising.
Specifies the frequency threshold
for stopping underfrequency-
caused raising.
