Description
The SUN2000L enters Standby mode when the external environment does
not meet the requirements for starting the SUN2000L. In Standby mode:
 The SUN2000L continuously checks its status and enters Operating
mode once the operating requirements are met.
 The SUN2000L enters Shutdown mode after detecting a shutdown
command or a fault after startup.
In Operating mode:
 The SUN2000L converts DC power from PV strings into AC power and
feeds the energy to the power grid.

The SUN2000L tracks the maximum power point to maximize the PV
string output.
 The SUN2000L enters Shutdown mode after detecting a fault or a
shutdown command, and enters Standby mode after detecting that the
PV string output power is not suitable for connecting to the power grid
and producing power.
