Hello

I have 2 Axpert king 5kw inverters running in parallel.  The settings on both are the same, however the fans on one runs with the load, slow with low load and fast with higher loads. But the second one runs on full speed all the time, they are both new. Is it something that can be fixed, they are close to our bed room and the noise is irritating.

Regards

Does it run full speed if it's the only machine running (e.g. you turn the other one off)?

A fan running full speed all the time sounds like a hardware problem to me.
