Question about using run/start capacitors
This is for any electricians versed in the use of load and run capacitors to help with ac surges on the genny or the inverter. I am in the middle of a teardrop build and I am trying to get away wi...

For now. Unfortunately there's a lot more to it than this simple test you've done ... not only will higher ambient temps and increased elevation make this much more difficult but so too will repeated attempts by the compressor to restart repeatedly. Lotsa luck if you actually believe the "naysayers" don't know what they're talking about. :R
yup. been there done that. thought I solved the problem with a better start cap. went from instant overload to start with a obvious grunt. This was near sea level and temps in the 80's. Went camping, sea level temps in the mid 90's and after about 3 tries I got it to start. inland at even 2500 ft and the mid 80's. nope. no luck
even the microair is not a complete solution. temps in the upper 90's at 4500 ft easy start on our coleman MachIII with the honda 2000 in eco mode, but the little honda is rated for 13.3A continous at sea level. that's close to the Mach III draw. after about 10 minutes the micro air would detect source overload and cut the compressor for 5 minutes, then restart. i suspect the generator inverter was either showing a voltage droop or varying current. The EMS didn't indicate low voltage, but close to it, around 110V afer 10 minutes. Initally the honda was around 115 and that's what it would stay at near sea level.
above about 4000 ft depending on temperature I need to parallel generators even with the micro air.
So..... before you claim success, test it in YOUR real world conditions.
