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.
