- If this parameter is set to Unlimited, the output power
of the inverter is not limited and the inverter can
connect to the power grid at the rated power.

controller
● If multiple inverters are cascaded, set this parameter
to SDongle/SmartLogger.
● If there is only one inverter, set this parameter to
Inverter.
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 Total power can be
selected. When a three-phase meter is connected in
three-phase three-wire mode, only Total power can
be selected.)
● Single-phase power indicates export limitation of
the power in each phase at the grid-tied point.
Single-phase power can be selected only if a three-
phase meter is connected in three-phase four-wire
mode.
Power
adjustment
period
Species the shortest interval for a single export
limitation adjustment.
Power control
hysteresis
Species the deadband for adjusting the inverter output
power. If the power uctuates within the power control
hysteresis, the power is not adjusted.
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.
