0
Inverter has just switched on
Only for a brief period after being fi rst switched on in the morning.
1
Waiting to start
Grid parameters and generator voltage are checked.
2
Waiting to switch off
Insuffi cient generator voltage and generator power. The status before
it switches over to night shutdown mode.
5
Grid feed mode
The inverter is feeding into the grid.
8
Self test
The line relay and the shutdown of the power electronics are tested
prior to the commencement of grid feed mode.
10
Overtemperature shutdown
If the inverter overheats (heat sink temperature > 85 °C) due to the
ambient temperature being too high and inadequate air circulation,
the inverter switches off.
12
Overload shutdown
Protective function of the inverter when too much generator power
is supplied.
13
Protection shutdown
Protective function of the inverter for short-lived line failures.
14
Line failure
Possible line failure causes:
• Line
overvoltage
• Line
undervoltage
•
Line impedance jump
15
Transition to night shutdown
Inverter switches from stand-by to night shutdown mode.
16
Operation stop
3 faults in self test – resumes after a complete shutdown.
24
DSP error
Possible causes of a fault in the control system:
•
Internal computing error (e.g. division by 0)
•
DC Link overvoltage
•
Control card overtemperature
•
Solar generator overvoltage
28
Hardware error
The self test was unsuccessful. There is a fault.
30
Measurement error
The current and voltage measurements in the inverter are not plau-
sible.
33
DC grid feeding error
The DC feed into the grid was too high.
34
Communication error
The DC feed into the grid was too high.
