The WhisperGen off-grid heat and power system provides an on-demand supply of heat as well as the power to run a number of electrical appliances. Available in a 12- or 24-volt model, the fully automated diesel-powered generator produces a noise level comparable to a household refrigerator, according to the manufacturer. The unit provides up to 800 watts DC output to automatically charge an electric-system battery bank; through an AC inverter, the battery bank powers lighting and appliances, handling peak demand that may exceed 5 kilowatts. The generator converts over 90 percent of the supplied fuel into heat and electricity, according to the manufacturer. The unit measures 14 inches wide by 20 inches deep by 25 inches high and weighs 198 pounds.
