table 7-2 Description of Inverter State
State
Description
Run
After being energized, inverter tracks the PV arrays’ maximum power
point (MPP) and converts the DC power into AC power. This is the nor-
mal operation mode.
Stop Inverter is stopped.
Key-stop
Inverter will stop operation by manually “stop” via app. In this way, inver-
ter internal DSP stops. To restart the inverter, manually start via app.
Standby
Inverter enters standby mode when DC side input is insufficient. In this
mode 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.
Warning Warning information is detected.
Derating
running
The inverter derates actively due to environmental factors such as tem-
perature or altitude
Scheduling
running
The inverter runs according to the scheduling instructions received from
the monitoring background
Fault
If a fault occurs, inverter will automatically stop operation, and discon-
nect the AC relay. The fault information will be displayed in the app.
Once the fault is removed in recovery time, inverter will automatically re-
sume running.
table 7-3 Description of PID Function State
State
Description
PID recovery
running
The inverters perform PID recovery actively.
PID abnormity
It is detected that the ISO impedance is abnormal or the PID function
cannot work normally after the PID function enabled.
If the inverter is running abnormally, the alarm or fault icon will be displayed in the lower
right corner of the inverter icon in power flow chart. The user can tap this icon to enter the
alarm or fault screen to view detailed information and corrective measures.
