Thanks for the replies.
I installed the hard wired unit into my trailer: Trailer plug > EMS > Distribution box. No transfer switch. No built in generator.
I carry a Yamaha 2400 generator, that according to Yamaha is MSW, safe for electronics.
I just installed a stand alone XANTREX 1000 watt Prosine True sine wave inverter. Permanetly hooked to the 2 group 27 marine batteries the trailer came with. But, not tied into the 120v AC system.
So, a couple of thoughts were: My inverter probabaly makes a better sine wave than my generator. But, there was no warning not to use an inverter generator....... Also, If I want to run on battery, I could run extension cords into the trailer and run specifc items. Or, I could plug the trailer into the inverter, shut off the converter, fridge and water heater, and then run what I want to run (CPAP, TV DVD), without having cords all over.
I called Prosine today and a technician called me back. He said the "Inverter" generators are fine. And even said I would need to bond the ground to neutral or bypass the unit to get it to work. But, they had not done testing on the "true Sine Wave" inverters. Although he knew some people that have tried it with no ill affects, he couldn't advise me to do it.
