Connection Unit LEDs
There are three LEDs on the lower board of the Connection Unit, near the DIP switches:
Figure 44: Connection Unit LEDs
l
In normal operation, the middle and bottom LEDs indicate auxiliary voltages (13V from DC/DC, 5V and
3.3V) and should always be lit.
l
The top LED should be lit when the inverter DC voltage is at least 200 Vdc (check when both inverter
ON/OFF switch and Connection Unit switch are ON). You can check the status screen for the Vdc
value.
l
If all LEDs are OFF:
o
Check that AC voltage exists in the inverter
o
Check that the communication cable between the Connection Unit and the digital board is
properly connected.
l
If the top LED is ON, and middle and bottom LEDs are off - an internal failure has occurred. Contact
SolarEdge support.
