Description
The SUN2000 enters standby mode when the external environment does not
meet the SUN2000 operation requirements. In this mode, the SUN2000
continuously performs a self-check and enters operating mode once
operation requirements are met.
The SUN2000 switches to shutdown mode when it detects a shutdown
command or a fault.
In this mode:

The SUN2000 converts DC power from PV strings into AC power and
feeds the power to the power grid.
 The SUN2000 always tracks the maximum power point to maximize the
PV string output.

The SUN2000 enters the shutdown mode after detecting a fault or a
shutdown command, and enters the standby mode after detecting that the
PV string output power does not meet the requirements for grid-tied
electricity generation.
The SUN2000 switches from standby or operating mode to shutdown mode
when it detects a fault or a shutdown command.
The SUN2000 switches to standby mode when it receives a startup
command or when it detects that a fault is rectified.
