Visual of how a A/C unit with an inverter compressor ramps up.

[CRM]

A short clip that some may find useful. It shows just how easily an inverter A/C unit ramps up and how it allows a much smaller generator to run it safely as compared to a standard compressor A/C unit. While this was on a Greenland Turbro, the numbers and ramp up profile should be very similar with any of the current units on the market. 

This test was using a Honda EU2200I generator and the readout is in volt-amps and not watts. VA actually topped out at 970VA but the video stopped right before the peak. After running 15 min power draw leveled out around 600VA and then down to 400VA after an hour or so. Should be able to get 6+ hours runtime on the .95 gallon tank if the A/C runs continuously. 

Not my plan to ever have to use the generator to power the Ollie, I just wanted to know how it would perform in an emergency situation where we're left without power for several days. Something everyone here in Florida thinks about during hurricane season!

Thanks for posting! I routinely use a small dual-fuel generator on propane for a/c at roadside or parking lot overnight stays when traveling. I carry a dedicated 30# tank that will provide enough power for three nights of use.  I have a larger dual-fuel for longer anticipated stays, such as hurricane evacuations on the Texas coast, which runs continuously on non-ethanol gas for the duration of stay. I can also run the a/c on inverter during rest stops and meals when traveling to a destination, utilizing 50% SOC for three hours of run time; the DC-DC charger will then recharge when back underway.
