Dougwalkabout, if the inverter has trouble starting the load you might want to look into a motor soft starter. I added one to my 8k btu AC unit in my travel trailer and my 2000 watt Honda inverter genny will start and run the ac in eco mode. It significantly reduces the inrush current. It is a bit pricey, the one for my ac was about $300 US. It might be a workable solution without upsizing your inverter.
