Inverter Cooling fans noisy
I have an 8kVA inverter, 7.2kVA Solar panels and export to grid. The inverter & batteries are installed in the pantry due to proximity to the DB, as unaware at installation that inverter fans rather noisy when cooling the unit. The fans do come on quite regularly (ca. 4-6 / hr) and is quite audible. Can these fans be replaced with other fans that are more quiet - i.e. similar to PC cooling fans?

I too was taken aback at how noisy the fans are - 65dB measured in front of the inverter.
The sound level is mentioned in the specs of the smaller inverters but not the 8kW inverter - I wonder why!
If there were smaller/slower/quieter fans that ran all the time rather than the noisy ones coming on and off it would help a lot. The noisy ones could then only come on if the machine got too hot. However having the fans run continuously at a slower rate, speeding up when necessary, would be much better for us, with the inverter in the utility room that is joined onto the kitchen/diner.
