On grid
(green LED glowing)
#60
The inverter is connected to the AC grid and feeds into the
grid. The inverter disconnects from the utility grid in the
following cases:
• The inverter recognizes abnormal grid conditions
(depending on the grid code).
• An internal event occurs.
• PV power is insufficient (no electric current has been
fed in for approx. ten minutes).
Internal inverter event
(green LED flashing)
#54
The inverter waits for an internal state within the thresholds
(e.g. due to too high a temperature) before reconnecting to
the utility grid.
Fail safe
(red LED flashing)
#70
If the inverter detects an error in its circuits during the self-test
(in the "Connecting" operating mode) or during operation,
it switches over to the "Fail safe" operating mode and is
disconnected from the utility grid. The inverter remains in the
"Fail safe" operating mode until the PV power has been
absent for ten minutes or the inverter has been shut down
completely (AC+PV).
3.2 Display
The integrated display on the inverter front gives the user
access to information about the PV system and the inverter.
