C Setting Export Limitation Parameters
Description
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.
Specifies the maximum active
power transmitted from the
grid-tied point to the power grid.
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.
