Below you will find a list of the most important states that have been configured for inverters

    Inverter status
NormalThe inverter is operating normally
ErrorThe inverter is in error but is producing
StoppedThe inverter has stopped producing
DisturbanceThe inverter has been disconnected from the grid
UnknownThe inverter has produced a status/error code that is characterized as Unknown in the datasheet
Night shutdownThe inverter has shutdown for the night
Communication ErrorThe controller cannot communicate with the inverter
WaitingThe inverter is waiting for the grid to stabilize or the panels to reach the operating voltage


A number of manufacturer-specific states are also supported

DSP fault statusFault present/not presentThe DSP of the inverter is malfunctioning
DC switch statusClosed/OpenThe switch on the DC side of the inverter is closed/open
AC switch status/ Output switch statusClosed/OpenThe switch on the AC side of the inverter is closed/open
Current statusNormal/OvercurrentThe inverter has no overcurrent condition/ The inverter has overcurrent condition
Neutral current statusNormal/OvercurrentThe inverter has not an overcurrent condition on the neutral/ The inverter has an overcurrent condition on the neutral
DC voltage statusNormal/Undervoltage/OvervoltageVoltage on the DC side of the inverter is within limits/ Voltage on the DC side of the inverter is below the lower limit/Voltage on the DC side of the inverter is over the higher limit
AC voltage statusNormal/Undervoltage/OvervoltageVoltage on the AC side of the inverter is within limits/ Voltage on the AC side of the inverter is below the lower limit/Voltage on the AC side of the inverter is over the higher limit
Inverter warning statusWarning present/not presentThere does not exist a warning for the inverter/ There exists a warning for the inverter (as defined in its datasheet)
Emergency stop statusNormal/Emergency stopNo emergency stop has been performed/ An emergency stop has been performed (in most cases through the relative button in the field)
Fan fault statusFan operational/Fan faultThe fan(s) is/ is not working properly within the inverter


Output frequency statusNormal/ErrorThe output frequency of the inverter is normal/ outside of the acceptable limits
Grid StatusGrid ready/ Grid not readyThe grid conditions are within/outside the operational envelope of the inverter
Inverter Fuse statusClosed/ OpenThe inverter fuse is working properly/ The inverter fuse is blown
Inverter sync statusSynced/Not SyncedThe inverter is /is not synchronized
Inverter temperature statusNormal/OvertemperatureThe inverter temperature is normal/ high
Earth fault statusPresent/Not PresentInverter indicates an earth fault (a short circuit between phase and earth)/ No earth fault present


Reactive PowerRegulation OffThe inverter is not regulating its reactive power
Regulation On
The inverter is regulating its reactive power
Reactive PowerLimitation OffThe inverter is not limiting its reactive power
Limitation OnThe inverter is limiting its reactive power
Active power Limitation OffThe inverter is not limiting its output active power
Limitation OnThe inverter is limiting its output active power


Apart from the inverters statuses, that are configured, most of the inverters provide error and status logs. If an inverter events occurs , you can view the inverter error/status logs and then refer to inverter manual in order to have a specific alarm description.

You can find the inverter error/status logs as shown below
