Figure 2-13 Working modes
Table 2-6 describes the working modes shown in Figure 2-13.
Table 2-6 Working mode 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.
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.
