C Setting Export Limitation Parameters
Description
Specifies the threshold for raising
the inverter output power.
In the inverter anti-backfeeding
scenario, if this parameter is set to
Enable, the inverter will derate
according to the active power
derating percentage when the
communication between the
inverter and the Dongle is
disconnected for a period longer
than Communication
disconnection detection time.
Specifies the time for determining
the communication disconnection
between the solar inverter and the
Dongle.
Specifies the derating value of the
inverter active power by
percentage. If the Dongle does not
detect any meter data or the
communication between the
Dongle and the inverter is
disconnected, the Dongle delivers
the derating value of the inverter
active power by percentage.
 Set this parameter to
SDongle/SmartLogger when
the SmartLogger1000A is
connected.

If multiple inverters are
cascaded, set this parameter to
SDongle/SmartLogger.
 If there is only one inverter, set
this parameter to Inverter.
 If this parameter is set to Total
power, it indicates that no
backfeeding occurs for the
three phases.
 If this parameter is set to
Single-phase power, it
indicates that no backfeeding
occurs for the phase with the
maximum power.
Specifies the total maximum
active power in the inverter
cascading scenario.
