C Setting Export Limitation Parameters
Description
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.
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.
