8kW inverter - pulsing fan under load
When under load the bottom fan on the side of my inverter pulses, while the other 2 are completely constant.
It sounds exactly as reported by this user/video, but only one of my fans is experiencing this issue: https://powerforum.co.za/topic/16934-sunsynk-8kw-fans-sounds-like-cars-revving/?do=findComment&comment=151787
It might be some PID bug, but I can't be sure. I cannot find a change log on the software versions, but is there possibly a software update that will address this?

Mine sounds exactly the same since going into summer
How can this be normal and what can be done about it?
