Description
Standby
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.
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 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.
Shutdown
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.
