Learn about Solis Error Code 1012, its causes, and how to fix DC injection issues during peak sun.
Error Code 1012 indicates high DC injection levels during peak sunlight, which can affect system performance.
To prevent DC injection issues, ensure proper system installation and regular maintenance checks to monitor performance.
Error 1012 is triggered when the inverter detects excessive DC injection, which can occur when the voltage from the solar array exceeds safe operational limits. This can result from several factors, including insulation resistance (RISO) measurements that indicate potential leakage, ground fault detection mechanisms that activate due to improper grounding, or grid frequency limits being exceeded. The inverter is designed to protect itself and the grid by shutting down under these conditions to prevent damage or safety hazards.
When the Solis S6 inverter displays Error 1012, users may observe blinking LED indicators, typically signaling fault conditions. The monitoring app may show a drop in energy production or indicate that the inverter is not operational. Additionally, there might be alerts regarding high DC injection levels during peak sunlight hours.
Always consult a licensed electrician or certified solar installer when working with electrical components to ensure compliance with safety standards and regulations.
To avoid encountering Error 1012 in the future, ensure proper system practices are followed, including correct string configurations and adequate grounding. Regular maintenance checks on the solar array and connections can help identify potential issues before they escalate. Keeping vegetation trimmed and monitoring system performance through the inverter's app will also aid in early detection of anomalies.
