C Setting Export Limitation Parameters
Description
If this parameter is set to
Unlimited, the inverter output
power is not limited. The inverter
can export its rated power to the
power grid.

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 shortest interval for a
single anti-backfeeding
adjustment.
Specifies the time for detecting
meter data. If the Dongle does not
detect any meter data within the
preset time, the Dongle delivers
the preset value of the Active
power output limit for fail-safe
to the inverter for protection.
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.
