Disturbance or fault
If the inverter detects a disturbance or fault, this is indicated through a blink code of the yellow and
red LEDs.
For example, if the yellow LED glows for 5 seconds immediately after connection, then goes out for 3
seconds and then flashes briefly twice, there is a grid fault. In this case, it may be due to the fact that
the AC cable has not yet been connected correctly or that the line circuit breaker has not yet been
switched on.
Meaning of the Blink codes
For a detailed description of the blink codes, see the operating instructions provided with
the Sunny Boy.
