Learn how to troubleshoot and fix a GoodWe inverter making a high pitched whistling noise.
A whistling noise in inverters can be caused by electrical components vibrating or loose parts. It's important to inspect the unit for any physical issues.
To prevent noise, ensure the inverter is securely mounted and check for any loose connections. Regular maintenance can also help reduce operational noise.
The high-pitched noise from the inverter is typically a result of electrical components resonating at certain frequencies. This can occur due to improper grounding, which affects the inverter's ability to stabilize its output. Additionally, the inverter utilizes pulse-width modulation (PWM) to control the output voltage and current, and any irregularities in the electrical circuit—such as ground faults or loose connections—can lead to abnormal oscillations, producing audible noise. The inverter's internal components, such as capacitors and inductors, may also contribute to this sound if they are failing or not functioning within their specified parameters.
Homeowners may notice a high-pitched whistling noise emanating from the GoodWe inverter during operation. This noise can often be accompanied by unusual LED patterns on the inverter display, such as blinking red or yellow lights, indicating potential faults. Monitoring apps may also report drops in energy production or display error codes related to inverter performance.
Always ensure that troubleshooting and repairs are conducted by a licensed electrician or certified solar installer to avoid electrical hazards and ensure compliance with local codes.
To prevent future occurrences of high-pitched noise, ensure that all connections are made properly and securely during system. Schedule regular maintenance checks to inspect grounding and electrical connections. Additionally, monitor the inverter's performance through its app or display, looking for early signs of anomalies.
