Status Explanation Comment
0 Inverter has just switched on Only after the first start-up in the morning.
1 Waiting for start Grid parameters and generator voltage are checked.
2 Waiting for shut-down Insufficient generator voltage and generator power.
Condition that precedes the night shutdown.
5 Grid feeding operation The inverter starts feeding into the grid.
15 Transition to night cut-off Inverter “goes to sleep”
16 Inhibited operation 3 errors during self test – operation will be resumed after
complete shutdown
24 DSP error error
- Communication error
- Grid shutdown frequency
- Offset (grid feeding is to high)
- High-temperature cut-off
- Transducer (Plausibility error – measuring technique)
- Impedance cut off
- Overload cut off
25 Self test of power electronics The shutdown behavior of the power electronics is
checked before the start of the grid-feeding process
26 Self test of grid isolation relay The grid isolation relay is checked before the start of the
grid-feeding process.
28 Hardware error Self test was unsuccessful, a defect has occurred.
