Message Explanation
Derating Reduction of the power fed into the power distribution grid due to high
heat sink temperatures
Disturbance Displays an error status that concerns the power distribution grid. This error
status resolves itself.
Error Error status that must be rectified
Grid monitoring When the system starts, the inverter performs a synchronization with the
power distribution grid.
MPP The inverter is in MPP mode.
The inverter adjusts the input voltage and the input current from the PV
array in order to achieve the highest possible DC output power.
MPP-Search When the system starts, the inverter tests the MPP tracking range.
Offset When the system starts, the inverter performs an offset calibration of the
electronics.
Stop The inverter has been manually set to system stop.
Turbine The inverter is in turbine mode.
This operating mode is specifically conceived for use with wind turbine
systems.
V-Const The input voltage of the PV array is set at a given target value and the
inverter is not operating in MPP mode.
This operating mode is suitable for using the inverter with fuel cells or small
hydroelectric power plants.
Wait DC voltage is not high enough to start.
Warning Error status that requires an additional inspection
