Thanks for the tips. That Yamaha is a good little genny, I have one myself. Our TC also has a built-in Generac 3600 LP gen that we use occasionally, but the vast majority of the time all we need is the Yamaha. It’s quieter, and more fuel efficient by far. Also, I expect the Generac is going to break someday, and it won’t be cost effective to fix it.
Like you, I have put in considerable time/effort/$$$ in making changes to my camper so that the Yamaha will meet all of our needs. I had given up on ever having A/C with this generator, so it’s nice to know it could be done if necessary. Most of the time we don’t need A/C when we’re dry-camping though.
I just recently went through the same search for a microwave that the Yamaha could handle. I bought a GE unit that had the smallest wattage rating I could find (600), hoping that it’s running wattage would be under 900. It was, but just barely. The Yamaha could handle the microwave in Arkansas at about 350 ft elevation, but couldn’t do it when we got above 1000 ft or so.
I recently installed a new 1500 watt pure sine inverter, and now we can use the microwave without having to start the big generator first. The Yamaha is usually running in the evenings when we’re out dry-camping anyway. The inverter needs about 93 amps of DC to run the microwave. When the generator is running, about 50 amps is supplied by the TC battery, and the rest is supplied by the generator through the campers converter/charger.
I’ve even run the microwave or coffee maker a few times off of the single group 31 AGM battery for 10-15 minutes with no generator running. The inverter is also used to run the refrigerator while we’re driving, and a heavy-duty charge circuit from the truck keeps up with the draw from the inverter.
