Description
Standby
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.
Operating
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.
