Joe, Thanks. I wasn’t looking to run all night at anchor. I was only thinking if we were moving under power with little to no breeze behind us, if it were possible to cool down the cabin a little, or at least get some relief standing in front of a vent for a short time.

The most benign thing that would go wrong would be the inverter overheating and shutting down. If that doesn't happen, running an alternator that hard for hours on end is pretty tough duty, I would not be surprised if the alternator died an early death. The worst case scenario is trying to run the AC at anchor. Long ago I dealt with a company that was selling 3 KW AC generators that belted off the main engine. End result was people running their engines all night to run the AC and carbon fouling them to death.
