Learn about the causes of a Low Production Warning on your inverter and how to troubleshoot it effectively.
Start by inspecting the inverter display for error messages and ensure that the solar panels are clean and unobstructed.
Yes, shading from trees, buildings, or debris can significantly reduce solar panel output, leading to low production warnings.
The inverter is designed to convert DC electricity from the array into AC for home use or export to the Utility Grid. A Low Production Warning can be triggered by several factors, including insufficient sunlight, electrical faults, or grid issues. Ground fault detection systems monitor for leakage currents that may indicate insulation failure, while RISO measurements assess the integrity of the insulation within the system. If the inverter detects conditions that could compromise safety or performance, it will enter a protective state, resulting in a production warning.
Homeowners may notice a Low Production Warning on the inverter display, often indicated by a specific LED pattern (e.g., blinking or steady red light). Monitoring applications may show significant drops in energy production, sometimes below expected performance levels based on solar irradiance data.
Electrical work can be hazardous. Always consult a licensed electrician or certified solar installer for troubleshooting and repairs to ensure compliance with safety standards and local codes.
Regular maintenance of the solar array, including periodic cleaning and inspection of connections, can help avoid production issues. Installing shading analysis tools can help identify potential obstructions. Additionally, ensuring the inverter is installed in a well-ventilated area can prevent overheating. Periodic testing of insulation resistance should also be part of routine checks.
