Description
The SUN2000 enters Standby mode when the external environment does not
meet the operating requirements. In Standby mode:
 The SUN2000 continuously performs status check and enters the
Operating mode once the operating requirements are met.
 The SUN2000 enters Shutdown mode after detecting a shutdown
command or a fault after startup.
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.

If the SUN2000 detects a fault or a shutdown command, it enters the
Shutdown mode.
 The SUN2000 enters Standby mode after detecting that the PV string
output power is not suitable for connecting to the power grid for
generating power.
