Sounds like your compressor or the capacitors starting it have died since running it 5 years ago. Simply ohm out the electrical lines gong to the compressor and see if you have open circuits that would be telling you there is a problem there. To double check, hook something of equal amp draw to the same circuit breaker and see if it blows.

Re: AC breaker tripping

"I think the inverter generator (Honda 2000 type) is really hot on both the hot and common side so using "
There are a number of posts online about portable generators (including the Honda's) and what the proper procedure is for using them in "ungrounded" installations, i.e. marine or portable use where the neutral and ground may or may not be connected to each other, and when a "true" ground may not exist.
There are reasons to do it both (either) way, including electrocution risks. As long as you're comfortable with the setup and understand what might happen, whatever floats your boat.

You found the different between an inverter generator (or just an inverter) and normal 120/240v US shore power. Shore power is split phase at 110V on each hot leg and a neutral center tap. The center tap being located at the zero crossing or 0V. The hot leg alternates from -60V to +60 volts giving 120V hot leg to ground. But an inverter or a inverter generator in this case, is a full wave in that both legs carry voltage. Just as you found out.
