If you were in my shoes, would you jump for the Champions, since it they would give me more power in reserve considering my elevation here in NM? Thanks for any feedback.
I consider this s tough question and would have to look to Yamaha owners for feedback. The CPE 2000i uses a minimal displacement engine, the bare minimum to meet its electrical power specs. The Yamaha 2400 on the other hand is "over-engined", having a larger displacement engine than needed for its ratings. It's the same displacement, 171 cc, that Yamaha uses in the 3000 watt inverter generator, making the ef2400is displacement greater than both of the Champions put together. So maybe, big emphasis on the maybe, the Yamaha won't be degraded by the altitude as much as the Champions. IMO the only way to know for sure is to test both setups at the actual altitude.
Congrats on reading the entire thread. I vote for some kind of attention span award!
For what its worth, here in Edmonton Alberta (elevation 2192 feet at 79 Fahrenheit), the ef2400is was not able to start my ac, but twin 2000i were no problem. I do not have a hard start, that might make it easier? I didn't read the amp draw or anything, this was a real life test with my friends ef2400is and my twin 2000i.
