Parameter Name Description
Limitation
mode
Total power indicates export limitation of the
total power at the grid-tied point. (When a
single-phase power meter is connected, only the
Total power limitation mode can be selected.)
Maximum
grid feed-in
power
Species the maximum active power
transmitted from the grid-tied point to the
power grid.
Power
adjustment
period
Species the shortest interval for a single export
limitation adjustment.
Maximum
protection
time
● Species the time for detecting power meter
data. If the Smart Dongle does not detect
any power meter data within the preset time,
the Smart Dongle delivers the preset value of
the Active power output limit for fail-safe
to the inverter for protection.
● The recommended value is 5s or greater.
Power
raising
threshold
Species the dead zone for adjusting the
inverter output power. If the power uctuates
within the power raising threshold, the power is
not adjusted. The recommended value is 1% to
2% of the inverter output power.
Active
power
output limit
for fail-safe
Species the derating value of the inverter
active power by percentage. If the Smart Dongle
does not detect any power meter data or the
communication between the Smart Dongle and
the inverter is disconnected, the Smart Dongle
delivers the derating value of the inverter active
power by percentage.
Communica
tion
disconnecti
on fail-safe
In the inverter export limitation 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 Smart Dongle is
disconnected for a period longer than
Communication disconnection detection time.
Communica
tion
disconnecti
on
detection
time
Species the fail-safe detection time in case of
disconnection between the inverter and the
Smart Dongle.
This parameter is displayed when
Communication disconnection fail-safe is set
to Enable.
