Message Explanation
Derating Reduction of the power distribution grid feed-in power due to abnormal
heat sink temperatures
Disturbance Indicates an error status related to the power distribution grid. The error
status will resolve itself.
Error Error status that must be remedied
Grid monitoring When the system starts, the inverter synchronizes with the power
distribution grid.
MPP The inverter is in MPP mode.
The inverter adjusts the DC input voltage and the DC input current of the
PV array to achieve the highest possible DC output power.
MPP-Search When the system starts, the inverter checks the MPP tracking range.
Offset When the system starts, the inverter calibrates the electronics.
Stop The inverter has been manually set to system stop.
Turbine The inverter is in turbine mode.
This operating mode was specifically designed for use with wind turbine
systems.
V-Const The DC input voltage of the PV arrays 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 The DC input voltage is not high enough for the start.
Warning System warning advising further investigation
