Using small fan to cool inverter | DIY Solar Power Forum

The internal fan turns on a lot making a loud metallic fan noise Ah, OK. I have had that happen on el-cheapo inverters too. I just usually replace the fan with a better, quieter one. Moving air through the middle of the device is still the best approach. There are components on the circuit board not attached to the case that also need to be

Strange Noise | Fronius Symo

Some have managed to stop the ticking noise by cycling the inverter off/wait/on, but others not so lucky. There seems to be at least 2 noise issues after this update - this new ticking sound and a different whine to the usual occasional fan noise. Some have mentioned the noise is only obvious or worse at around 50% PV generation.
