Fantastic fan sped

Installed a new Fantastic fan and wired it into the adjacent light as per the SM at the dealer location. I find that it runs much faster (and noisier)on shore power than it does on storage battery power. Also does not seem to be much speed difference between the 1st and 2nd postion. Batteries are new and there are two in service. This is on a Thor 24c Chateau.
Any ideas of why this is happening?

/check the voltage of your battery bank while under load both while unconnected then when connected to shore power. I suspect your battery bank is not fully charged and when on shore power the converter is supplying dc to the bank

The converter/charger will supply, approx. 1.5 v more power than the batteries alone so some increase will occur. The lower 2 speeds are the , constant run settings and so designed to be quieter , while high is clear the whole unit in a hurry setting and the noise is not a factor because they don't expect you to have to leave it on high for long.
If you really consider the noise a problem , first check your charger out-put, should be 13.2 to 13.5 at the batteries, after a few hours plugged in .
I see KIX, types faster than I do. Most people do .
