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.
• The energy generated today and the current
operating mode are displayed first.
• After 5 seconds or by tapping on the housing lid,
the current feed-in output and the PV 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 begins again.
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 fault 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 circuit breaker is not switched on
yet.
• If a non-standard compliant measured value is
responsible for the disturbance, then the value
measured at the time of the fault is displayed. If
another measurement is possible, the present value
is displayed in the second line.
Refer to the delivered user manual of the Sunny Boy to read the exact explanations for the error and
status messages!
