8.5.4 Operating Parameters of the Sunny Boy
l
Stop: Manual system stop
Offset: Offset calibration of the electronics (at start-up)
Waiting: PV voltage is not high enough to start
Grid monitoring: Synchronizing to grid (at start-up)
MPP-Search: MPPT range test (at start-up)
MPP: Sunny Boy is in MPP mode (standard operation)
V-Const: Sunny Boy is in MPP mode with constant voltage
Derating: Reduction of the power fed into the grid due to increased cooling element
temperatures
Disturbance: Fault status relating to the grid. As soon as the cause of the fault is no longer
present, this fault will be reset automatically.
Error: Inverter fault, user interaction required

The Sunny Boy evaluates the yield
and displays the approximate
amount of CO2 that the Sunny Boy
has saved.
This CO2 amount is calculated by
multiplying the generated kWh (E-
total) by the factor defined in the
parameter "CO2".
