They use the same inside panel for several different models, so it's hard to determine the BTU on your unit by just looking at the inside panel. As you mentioned it's probably a 13.5k BTU. At any rate, it was good news to hear it powered up your a/c and then dropped down to a lower idle. Kinda gives the impression there's some decent headroom available. I assume you had the ECOnomy mode on?otrfun wrote:
bmzero, thanks for the info and update! I'm sure a few folks here are curious whether it runs your a/c successfully with the ECOnomy mode both off and on. Please give us an update (along with the size of your a/c unit) when you get a chance. Thanks!
The main purpose of this generator is to run the A/C in a box truck I'm building for racing. That truck doesn't have the air installed yet, so I can't test it on that truck, but I did hook it up to our race trailer to test it out. That trailer has two roof airs and runs an Onan 7000. I plugged the trailer into the Champion 3100w and gave it a shot. It handled a single A/C unit perfectly fine (didn't try both units simultaneously) and even idled back down after the A/C kicked on. Unfortunately, I couldn't find the model number or size of the A/C's in any of the documentation. I'm sure they're at least 13.5k. I put in some photos of the A/C's bottom panel in case that's enough for some of you to determine the size of it.
My plan is to pull the trigger on one of these Champion 75531i 3100/2800 inverter generators in the next week or so even though there's no long-term, reliability stats on this generator. IMO, the 75531i's good preliminary online feedback, Champion's good warranty support (most online comments are positive), excellent specs for this unit (at least on paper), and especially the low price ($900-$999), makes this generator a good purchase risk. The online retailer I talked to is willing to allow a 14-day return period. As long as it powers up my 13.5k BTU Coleman a/c, then I'm sure I'll be a happy and cool camper! Thanks again, bmzero!
