Learn about the causes of a Goodwe DC undervoltage alert on solar panels and how to troubleshoot it effectively.
Common causes include low sunlight conditions, faulty wiring, or issues with the inverter settings.
Check the solar panel connections, ensure proper sunlight exposure, and verify inverter settings for optimal performance.
The Goodwe inverter monitors the voltage levels of the solar array to ensure they remain within specified operational parameters. A DC undervoltage alert typically triggers when the voltage falls below the inverter's programmed threshold, which may be due to several factors affecting the electrical performance of the array. The inverter employs insulation resistance measurement (RISO) and ground fault detection to ensure safety and operational integrity. When the voltage dips, it indicates that the power generated is insufficient to meet the inverter's minimum operational requirements, potentially leading to inefficient energy conversion or system shutdown.
Homeowners may notice an alert on the inverter's display or in the monitoring app indicating a DC undervoltage condition. Visual indicators can include blinking LED lights or error messages. Additionally, a significant drop in solar production may be observed, with the system output falling below expected levels, often below the minimum voltage threshold set for optimal inverter operation.
Working with electrical systems can be hazardous. Always engage a licensed electrician or certified solar installer for troubleshooting and repairs.
To avoid future DC undervoltage alerts, conduct regular maintenance checks on the solar array, including cleaning panels and inspecting connections. Ensure that the inverter settings are correctly configured and stay updated with any firmware updates that may improve performance. Additionally, consider conducting annual performance assessments to identify potential issues early.
