4.2 LED displays
The inverter is equipped with three LEDs that give information about
the various operating statuses as follows:
1
2
3

Figure 4.2: LED displays
LED (1) (green):
The LED begins to light up when the minimum voltage from a pho-
tovoltaic array is present and goes out again if the array voltage is
lower than the minimum operating voltage. The LED signals that the
inverter is in stand-by mode. If it is illuminated the inverter is ready for
operation or is currently operating.
LED (2) (green):
The LED is lit when the inverter is feeding into the grid.
LED (3) (red):
The LED indicates that the grid-feed was stopped due to a fault.
Wait approx. 10 mins. to see if the fault is temporary. If this is not the
case, notify your authorized electrician.
IMPORTANT
If there is a power failure on the public grid, LED (3) does not light
up. If this happens, all LEDs and the display go out. The inverter
is shut down completely.
The inverter can only resume its normal operation when the public
utility grid is available again.
Check whether the fault in question relates to a general power failure
or whether the circuit breaker between the utility service and the
inverter has tripped. If the circuit breaker has tripped, notify your
authorized technician. If there was a power failure, simply wait until
the fault has been cleared. The system automatically re-starts.
4.3 Keys “1” and “2”
Figure 4.3: blueplanet control keys
Key “1” is used to switch between the various displays for measured
values and data. You use key “2” to configure settings. Here, menu
navigation is divided into two levels. In level 1 (display mode), measu-
red values such as the solar generator voltage can be read. Here, only
key “1” is activated. In level 2 (configuration mode), key “1” is used to
navigate through the individual displays and settings.
ACTION
By pressing key “1” you can choose which measu-
red value is to be displayed.
The menus are continuous, which means that
when you arrive at the last entry in a menu, the
first entry is displayed again the next time key “1”
is pressed (see Figure 4.4).
