Description
Maximum grid Specifies the maximum active power transmitted from the grid-tied
feed-in power point to the power grid.
Power Specifies the shortest interval for a single anti-backfeeding
adjustment adjustment.
period
Power control Specifies the dead zone for adjusting the SUN2000 output power. If
hysteresis the power fluctuation is within the power control hysteresis, the
power is not adjusted.
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 SUN2000 anti-backfeeding scenario, if this parameter is set to
disconnection Enable, the SUN2000 will derate according to the active power
fail-safe derating percentage when the communication between the SUN2000
and the Smart Dongle is disconnected for a period longer than
Communication disconnection detection time.
Communication Specifies the time for determining the communication disconnection
disconnection between the SUN2000 and the Dongle.
detection time
This parameter is displayed when Communication disconnection
fail-safe is set to Enable.

Limitation mode Total power indicates export limitation of the total power at the
grid-tied point.
PV plant Specifies the total maximum active power in the SUN2000
capacity cascading scenario.
Maximum grid Specifies the percentage of the maximum active power of the
feed-in power grid-tied point to the PV plant capacity.
Power Specifies the shortest interval for a single anti-backfeeding
adjustment adjustment.

power is not adjusted.
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.

If multiple SUN2000s are cascaded, set this parameter to
SDongle/SmartLogger.
If there is only one SUN2000, set this parameter to Inverter.
