Running a microwave from Vanagon batteries would be tough. This small 600-watt oven, for example http://www.haieramerica.com/en/product/MWM6600RW uses 950 watts of power. That means give or take one hundred amperes out of your battery, and to support that kind of draw you should have 300 (for AGM or gel batteries) or 400 (for conventional batteries) amp-hours of battery capacity so as not to damage the batteries from too fast a discharge. I think you'd be much better off looking into a steam sterilizer that you can run off the stove. IIRC the stove burners are rated at 5600 BTU/hr each, which is the same or slightly larger than a regular stove burner. A full propane tank should give you in the area of 48 hours burning time for one burner. Here's a ten-quart one at a not-too-outrageous price: http://www.amazon.com/All-American-9-5-Quart-Pressure-Sterilizer/dp/B000S8G1TS Yours, DAvid |
