2019 Winnebago Revel Air Conditioner Upgrade.

Sunchaser Van Conversions



Special thanks to Nomadic Cooling for opportunity to become an approved dealer and installer of their AC units. Nomadic Cooling provided us with detailed instructions, training and understanding of such a great product in Van Conversion market. 12V AC units will become a big game changer for off-grid adventurers and explorers.


No more “only shore-power AC” that limits use and comfort of your Revel. Nomadic Cooling moved goal post a little further.


We conducted initial testing of 3000-75A AC unit and results were awesome!

For example;

Unit 3000 with 75A compressor in ECO mode will drain around 35Ah from our SC630 (630Ah) lithium battery package.

So, you do the math.

Or, lets help you a bit; 630/35 = 18 hours of constant run time, BUT…

For 1 hour of testing unit didn't run with full load of 35Ah. 52% of time unit did draw 35Ah and rest of time dropped to 8Ah while using only fan to circulate air in Revel bedroom.

Lets do some more math;

52% of 35Ah = 18.2Ah

48% of 8Ah = 3.8Ah

Total draw for 1 hr = 22Ah and WOW!!!!!


This test was conducted at 75F outside temperature, Van in direct sun, 86F inside temperature and thermostat set at 70F. Many variables will impact this formula and power consumption, but we can comfortably say that under constant full load you will have 18+ hours of AC in ECO mode at your disposal.


Not to mention that adding a 60A DC-DC charger in a mix will extend run time of your 12V AC unit while diving and still top off you battery storage.
