Description
The solar inverter enters the standby mode when the external environment
does not meet the requirements for starting the solar inverter. In the standby
mode:
 The solar inverter continuously checks its status and enters the operating
mode once the operating requirements are met.
 The solar inverter enters the shutdown mode after detecting a shutdown
command or a fault after startup.
In operating mode:
 The solar inverter converts DC power from PV strings into AC power
and feeds the power to the power grid.
 The solar inverter tracks the maximum power point to maximize the PV
string output.
 The solar inverter 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 to
produce power.
