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.
