Description
The SUN2000 enters Standby mode when the external
environment does not meet the requirements for starting the
SUN2000. In Standby mode:
● The SUN2000 continuously detects its operation status. Once
the operation conditions are met, the SUN2000 enters
Operating mode.
● If the SUN2000 detects a shutdown command or a fault after
startup, it enters Shutdown mode.
In Operating mode:
● The SUN2000 converts DC power from PV strings into AC power
and feeds the power to the power grid.
● The SUN2000 tracks the maximum power point to maximize
the PV string output power.
● If the SUN2000 detects a shutdown command or a fault, it
enters Shutdown mode.
● If the SUN2000 detects that the output power of PV strings
does not meet the requirements for grid-tied power generation,
it enters Standby mode.
● In Standby or Operating mode, if the SUN2000 detects a
shutdown command or a fault, it enters Shutdown mode.
● In Shutdown mode, if the SUN2000 detects that the fault is
rectified or the startup command is executed, the SUN2000
enters Standby mode.
