Run
After being energized, the inverter tracks the PV arrays’ maximum
power point (MPP) and converts the DC power into AC power. This is
the normal operation mode.
Stop The inverter is stopped.
Key-stop
The inverter will stop operation by manually “stop” via app. In this
way, inverter internal DSP stops. To restart the inverter, manually
start via app.
Standby
The inverter enters standby mode when DC side input is insufficient.
In this mode the inverter will wait within the standby duration.
Initial standby The inverter is in the initial power-on standby state.
Starting The inverter is initializing and synchronizing with the grid.

Fault
If a fault occurs, the inverter will automatically stop operation, and
