7.1 LED States
7.1.1 Operation LEDs
Configuration of the Status LED ( ):
The status LED can display the following statuses:
• Status of the Cluster Controller
• Status of the connected inverters
• Status of the system communication
• Status of the grid management services
In this document, the only states described below are those that the status LED can adopt during
commissioning (for a complete description of the states, see the Cluster Controller user manual).
If the status LED is not glowing green after commissioning, refer also to the event log of the
Cluster Controller to determine the precise cause of the error. The details of each error are logged
in the event log (see the Cluster Controller user manual).
LED Status Cause and corrective measure
All off The Cluster Controller is not connected to the voltage
supply.
Corrective measures:
• Connect the Cluster Controller to the voltage
supply (see Section 6.13, page 64).
The voltage supply is reverse-connected or the power
supply unit is defective.
Corrective measures:
• Ensure that the voltage supply is correctly
connected (see Section 6.13, page 64).
• If the voltage supply is connected correctly,
replace the power supply unit.
