Description
Standby
The SUN2000 enters Standby mode when the external environment does not
meet the requirements for starting the SUN2000. In Standby mode:
The SUN2000 continuously performs self-check and enters Operating
mode once the operating requirements are met.
The SUN2000 enters Shutdown mode after detecting a shutdown
command or a fault after startup.
Operating
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.
The SUN2000 enters Shutdown mode after detecting a fault or a
shutdown command, and enters Standby mode after detecting that the
PV string output power is not suitable for connecting to the power grid
and producing power.
Shutdown
In Standby or Operating mode, the SUN2000 enters Shutdown mode
after detecting a fault or shutdown command.
In Shutdown mode, the SUN2000 enters Standby mode after detecting a
startup command or that the fault is rectified.
