Learn about Sol-Ark Error Code F18 AC Frequency Low and how to resolve it during generator backup.
The F18 error indicates that the AC frequency is below the acceptable range during generator operation, which can affect performance.
Check the generator's output frequency and ensure it is within specifications. Adjust settings if necessary.
The F18 error indicates that the inverter has detected an AC frequency below the acceptable threshold, triggering a protective response. Inverters are designed to operate within specific frequency limits to ensure the stability of the electrical system. If the frequency falls below these limits, the inverter will disconnect to prevent damage. This situation often arises when the generator supplying power to the inverter is malfunctioning or improperly configured, as the inverter relies on the generator to maintain a stable AC frequency.
When the Sol-Ark inverter displays the fault code F18 AC Frequency Low, users may notice a flashing LED indicator on the inverter, accompanied by alerts on the monitoring app indicating reduced power output or system shutdown. The inverter may not produce any power, or the energy production may drop significantly, especially during generator backup operations.
Always consult a licensed electrician or certified solar installer when troubleshooting or repairing electrical systems to ensure compliance with safety standards and regulations.
To prevent the F18 error from occurring in the future, ensure that the generator is properly sized for the inverter's load requirements. Regular maintenance of the generator, including checks on the governor and electrical connections, can help maintain optimal performance. Additionally, keeping the inverter firmware updated will help mitigate potential software-related issues.
