4.1.3 Power Display
The output power and the battery charging power of the inverter are displayed by
means of the number of boxes which appear in the upper row of the display. This is
a relative indication of the inverter's output, i.e. if the boxes extend to the middle of
the scale, this shows that the Sunny Island 3324/4248 is operating at half of its
nominal output.
4.1.4 Relay Status
In the lower right-hand corner of the green display screen appear two "O"s.
Load shedding: the left "O" indicates the status of the load shedding relay of the
Sunny Island 3324/4248. "O" stands for "Off" or "Open". If the relay closes, the "O"
is filled.
Generator Start: the "O“ on the right-hand side indicates the status of the
generator control relay in the same manner. It is closed if the Sunny Island 3324/
4248 intends to start the generator.
