Learn how to troubleshoot and resolve underfrequency issues with Tigo Energy 305 AC optimizers.
Underfrequency can occur due to grid instability or equipment malfunction. It's essential to check the grid frequency and the optimizer's settings.
To reset your Tigo Energy optimizer, power it down and then restart it after a few minutes. This can help clear temporary faults.
The Tigo Energy 305 AC optimizer is designed to operate within specific grid frequency limits, typically around 60 Hz. When the grid frequency falls below these limits, the inverter triggers a fault condition to protect both the system and the utility grid. This underfrequency condition can occur due to various reasons including fluctuations in the utility grid, which may be caused by high demand or generation issues. The optimizer continuously monitors the grid frequency and voltage to ensure safe operation, and when it detects an anomaly, it enters a protective shutdown mode.
Homeowners may notice the optimizer's LED indicator displaying a steady orange or red light, signaling an underfrequency condition. Additionally, monitoring apps may report a significant drop in energy production or show alerts indicating that the optimizer is not operating within expected grid frequency parameters.
Always consult a licensed electrician or certified solar installer for troubleshooting and repairs to ensure compliance with local codes and safety standards.
To avoid underfrequency issues in the future, regularly inspect and maintain the entire solar array system, ensuring all components are functioning correctly. Implement routine checks on the utility grid frequency and voltage levels, and keep the firmware of the optimizer updated to the latest version. Additionally, ensure proper shading analysis during system to minimize performance drops.
