Can Onan Microlite 2.8 handle a 13,500 BTU A/C?

I decided to go with an 11,000 BTU unit.

I called Onan and they said I could run a 13,500 at near sea level, but I'm at 4,500 feet in Salt Lake City. I think I'm pushing my luck.

Interesting.

Is the standard genset a 4.0 Kw for a 13,500 A/C unit?

The Winnebago Travato is shipping with a 13,500 BTU A/C with a MicroLite 2800 gasoline genset, so either the A/C has some good soft-circuitry to help lower the locked rotor amps crashing against the genset, or the genset should work without issue, although I wouldn't be running the microwave with the A/C on.

For those of you that have 13,500 BTU A/C units on your RV, what size is your factory installed generator?

I had one on a WW toyhauler. It would but if you hit the toaster the gen would lug and slowly recover. Not good. Just watch how much you load it. If the gf was with me. I shut down the a/c while she used a blowdryer. That was too much for it. So I started leaving her home and since leave her home all the time. Haven;t heard from her in months, LOL.

LOL :B

Power(in watts)= current(amps)X AC volts...ie: if the 13500 draws 20 amps at initial startup and U'r average AC Volts is approx. 118... 20 X 118 = 2360 Watts
Question... Is this genny 2.8(2800)watts continous run power or its momentary 'Peak' output power?
After initial startup, U'r genny probably only draws about 13 amps running.
13 X 118 = 1534 watts.
If U get this AC unit, monitor the AC voltage at any outlet. Never let it be loaded to the point that it goes below 107 Volts AC. Too low voltage will ruin the AC compressor.

My Onan 2.8 microlite is only a 2.5 since it is Propane (LP) and it starts my Dometic duo therm brisk air 13500 with no problem (1500 ft and 110 degrees).
Im not even sure my AC has a start cap, as in the wiring diagram it says some models do not have. Going to remove the cover and check soon to see if it is there.

My 2.8 starts and runs my 15,0000.

Dometic makes a start kit for this- part number 3102903.006 "QUICK START KIT"

From the install sheet (at http://bryantrv.com/docs2/docs/quickstart.pdf):
"The Quick Start Kit can be installed on all Duo-Therm roof mounted air conditioners and heat pumps. The Quick Start Kit will
allow the compressor to start properly when operated on the Onan 2.8 Micro-Lite Generator as the 120 volt power source."

It is a potential relay and start capacitor.
