Description
After being energized, inverter tracks the PV arrays' maximum
power point (MPP) and converts the DC power into AC power.
This is the normal operation mode.
Inverter is stopped.
Inverter will stop operation by manually "stop" via app. In this
way, inverter internal DSP stops. To restart the inverter,
manually start via app.
Inverter enters standby mode when DC side input is
insufficient. In this mode inverter will wait within the standby
duration.
The inverter is in the initial power-on standby state
The inverter is initializing and synchronizing with the grid.
Warning information is detected.
The inverter derates actively due to environmental factors such
as temperature or altitude
The inverter runs according to the scheduling instructions
received from the monitoring background
If a fault occurs, inverter will automatically stop operation, and
disconnect the AC relay. The fault information will be displayed
in the app. Once the fault is removed in recovery time, inverter
will automatically resume running.
Description
The inverters perform PID recovery actively.
The inverter is suppressing the PID effect.
It is detected that the ISO impedance is abnormal or the PID
function cannot work normally after the PID function enabled.
