AC in high limit setting

I have a 20kw Generac generator I use for charging. It is generating between 146 and 148 volts on each leg. Is it safe to raise the ac voltage in setting above the 140 V default of my Outback system?

The FX series programming manual says the upper AC IN limit range is 130-150VAC, so you should be okay, assuming that's the manual that applies to your inverter:

Also keep in mind the OutBack doesn't condition the voltage it will just pass through the generator power straight to your house so your loads will receive this higher voltage.

I wonder if you can adjust the voltage regulator (AVR?) on the genset in order to bring the voltages down to ~120V, where they are intended to be?
I have noticed that some appliances do not operate properly if they are not close to 120V. I can see 110V-130V range but 148V is getting up there??

Thank you all! Great advice. I will be working with the generator to get the voltage corrected before attempting to connect it to the system. Thanks again...

Yes, 16 C and 31 C are the limits in the split AC in my room. I normally use it between 21 and 27 depending on the outside weather. I also switch it ON and OFF periodically and in addition use the ceiling fan to keep the air comfortable and reasonably dry.
