Description
Power Specifies the shortest interval for a single anti-backfeeding
adjustment adjustment.
period
Power control Specifies the dead zone for adjusting the SUN2000 output
hysteresis power. If 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
output limit by percentage. If the Smart Dongle does not detect any
for fail-safe meter data or 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.
Communicatio In the SUN2000 anti-backfeeding scenario, if this parameter
n is set to Enable, the SUN2000 will derate according to the
disconnection active power derating percentage when the communication
fail-safe between the SUN2000 and the Smart Dongle is
disconnected for a period longer than Communication
disconnection detection time.
Communicatio Specifies the time for determining the communication
n disconnection between the SUN2000 and the Dongle.
disconnection
This parameter is displayed when Communication
detection time
disconnection fail-safe is set to Enable.
Closed-loop ● If multiple SUN2000s are cascaded, set this parameter to
controller
● If there is only one SUN2000, set this parameter to
Limitation Total power indicates export limitation of the total power
mode at the grid-tied point.
Maximum grid Specifies the maximum active power transmitted from the
feed-in power grid-tied point to the power grid.
Power Specifies the shortest interval for a single anti-backfeeding
adjustment adjustment.
