Learn about the Yellow Halo error on Wallbox Pulsar Plus and how to resolve it effectively.
The Yellow Halo error typically indicates a charging issue or a fault in the connection. It is essential to check the power supply and connections.
To troubleshoot, ensure the charger is properly connected and the power source is functional. If the issue persists, consult the user manual or contact support.
The yellow halo error indicates that the inverter has detected a fault condition that requires immediate attention. This could stem from a ground fault, where current leaks to the ground due to compromised insulation. The inverter continuously monitors parameters such as insulation resistance (RISO), grid frequency, and current flow. If any of these parameters deviate from established thresholds, the inverter triggers the yellow halo as a protective measure. This is in line with NEC standards, which mandate strict safety protocols to prevent electrical hazards.
The Wallbox Pulsar Plus displays a yellow halo around the LED indicator. This visual cue signifies a fault condition. Users may also receive alerts via the monitoring app, and there may be a noticeable drop in charging performance or complete cessation of charging activity.
Always consult a licensed electrician or certified solar installer when diagnosing or repairing electrical faults. Safety should be your top priority.
To avoid this issue in the future, conduct routine inspections of the wiring and connections, ensuring they are secure and free from wear. Regularly test insulation resistance and maintain proper ventilation around the inverter. Additionally, stay informed on grid frequency variations and ensure your equipment complies with NEC standards.
