● If multiple SUN2000s are cascaded, set this parameter
to SDongle/SmartLogger.
● If there is only one SUN2000, 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
meter is connected, only Total power can be selected. If
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. If a three-
phase meter is connected, Single-phase power can be
selected only when the meter is connected in three-
phase four-wire mode.
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
Dongle does not detect any power meter data within the
preset time, the Dongle delivers the preset value of Active
power output limit for fail-safe for protection.
Power raising
threshold
Species the step for grid-tied power adjustment.
