6.1 Display Message
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 output voltage
are displayed.
• After a further 5 seconds, or when you tap again,
the current input voltage and the input power are
displayed.
• 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
• In case of a failure, the message "Disturbance" will
be indicated 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 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.
