Explanation
Reduction of the power fed into the power distribution grid due to high
heat sink temperatures
Displays an error status that concerns the power distribution grid. This error
status resolves itself.
Error status that must be rectified
When the system starts, the inverter performs a synchronization with the
power distribution grid.
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.
When the system starts, the inverter tests the MPP tracking range.
When the system starts, the inverter performs an offset calibration of the
electronics.
The inverter has been manually set to system stop.
The inverter is in turbine mode.
This operating mode is specifically conceived for use with wind turbine
systems.
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.
DC voltage is not high enough to start.
Error status that requires an additional inspection
