Startup phase and feeding energy into the grid
Startup phase Once it has been switched on automatically, the inverter carries out the following tests and
checks:
a) Self-test of all important inverter components - the inverter runs through a virtual
checklist
b) Synchronisation with the grid
c) Startup test
Before the inverter starts feeding energy into the grid, the grid conditions according to
national regulations are tested.
Depending on the country-specific regulations, the startup test can last just a few sec-
onds or take several minutes.
During the startup phase:
- the operating state LED shows orange,
- the string 'warte...' (wait...) and the currently tested component are displayed, e.g.:
Feeding energy
into the grid
- Once the tests have been completed the inverter starts feeding energy into the grid
- The display shows the current energy level that is being fed into the grid, e.g.:
- The operating state LED shows green, the inverter is working.
