Description
- If this parameter is set to Unlimited, the output power of the
SUN2000 is not limited and the SUN2000 can connect to the
power grid at the rated power.

Power Specifies the shortest interval for a single export limitation
adjustment adjustment.
period
Maximum Specifies the time for detecting power meter data. If the Dongle
protection time 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 Specifies the step for grid-tied power adjustment.
threshold
Active power Specifies the derating value of the SUN2000 active power by
output limit for percentage. If the Smart Dongle does not detect any meter data or
fail-safe the communication between the Smart Dongle and the SUN2000 is
disconnected, the Smart Dongle delivers the derating value of the
SUN2000 active power by percentage.
Communication In the inverter export limitation scenario, if this parameter is set to
disconnection Enable, the inverter will derate according to the active power
fail-safe derating percentage when the communication between the inverter
and the Smart Dongle is disconnected for a period longer than

If multiple SUN2000s are cascaded, set this parameter to
SDongle/SmartLogger.
If there is only one SUN2000, set this parameter to Inverter.
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.)
Single-phase power indicates export limitation of the power in
each phase at the grid-tied point.
