Learn how to troubleshoot Solis Error Code 1011 related to grid overvoltage protection issues.
Error Code 1011 indicates a grid overvoltage condition that the inverter is protecting against. This is a safety feature to prevent damage.
To resolve grid overvoltage issues, check the voltage levels at the inverter and ensure they are within acceptable limits. If the problem persists, consult your utility provider.
The Solis inverter triggers Error 1011 when it detects that the grid voltage has exceeded its predefined limits. This is a crucial safety feature designed to prevent damage to the inverter and connected components. The inverter continuously monitors the input voltage levels against the utility grid's voltage. If the voltage exceeds the maximum threshold—typically around 264V AC—the inverter will initiate a shutdown. This can occur due to several factors, including utility grid fluctuations, faulty voltage sensing components, or configuration errors during system.
Upon encountering Error 1011, users may observe the inverter's LED indicator flashing in a specific pattern—often a continuous blink or color change indicating a fault. Additionally, monitoring apps may display alerts regarding grid overvoltage, and there will likely be a noticeable drop in energy production, as the inverter will cease to operate to protect itself from potential damage.
Always consult a licensed electrician or certified solar installer when troubleshooting electrical issues to ensure safety and compliance with local regulations.
To prevent future occurrences of Error 1011, ensure regular maintenance of the inverter and surrounding electrical systems. Periodically check the grid voltage and monitor for any fluctuations. Additionally, confirm that the inverter’s firmware is up to date and that system parameters are correctly set according to local utility requirements. Consider installing surge protection devices to safeguard against transient voltage spikes.
