Feeding Operation
After fault-free grid connection of the Sunny Boy, it takes approximately one minute until the following
display messages are shown alternately. The display messages shown before only have the purpose
of indicating the initialization of the Sunny Boy and the process of controlling whether the power
supply requirements are fulfilled.
Initially, the energy generated on the respective
day and the current operating mode are displayed.
After 5 seconds or by tapping on the enclosure lid,
the current feed-in output and the input voltage
appear.
After a further 5 seconds, or when you tap again,
the total energy produced and the time the Sunny
Boy has been connected to the grid are displayed.
Then the cycle is restarted.
Disturbance
If a disturbance occurs, the message "Disturbance"
will be shown in the status bar.
The exact failure message follows.
For example, if the grid disturbance message
shown here is displayed immediately after
connection, it may be due to the fact that the AC
wire is not correctly connected or the line circuit
breaker has not been switched on yet.
If the disturbance was caused by a measured value
that does not correspond to the standard, the value
measured at the time of the disturbance is
displayed. If another measurement is possible, the
present value is displayed in the second line.
The precise meaning of the error and status messages are described in the Sunny Boy's user manual
provided.
