Description
The SUN2000 enters the standby mode when the external environment does
not meet the SUN2000 operation requirements. In standby mode, the
SUN2000 continuously performs self-check and enters the operating mode
once the operation requirements are met.
The SUN2000 switches from standby mode to shutdown mode if it detects a
shutdown command or a fault.
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 the shutdown mode if detecting a fault or a
shutdown command, and enters the standby mode if 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
if detecting a fault or a shutdown command.
The SUN2000 switches from shutdown mode to standby mode if receiving a
startup command or detecting that a fault is rectified.
