Parameter Name Description
Active
power
Unlimited - 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 control
hysteresis
^Ý²Ēä the dead zone for adjusting
the SUN2000 output power. If the
power ēñìñì²ÑÊ is within the power
control hysteresis, the power is not
adjusted.
Active power output
limit for fail-safe
^Ý²Ēä the derating value of the
SUN2000 active power by percentage.
If the Smart Dongle does not detect
any 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.
Communication
disconnection fail-safe
In the SUN2000 anti-backfeeding
scenario, if this parameter is set to
Enable, the SUN2000 will derate
according to the active power
derating percentage when the
communication between the
SUN2000 and the Smart Dongle is
disconnected for a period longer than
Communication disconnection
detection time.
