24 VDC appliances?
"misia" wrote in message ail.from.there... On my new boat I will have a powerfull 24VDC battery bank charged by a diesel generator and auxiliary sources. How powerful? Are you talking about a thousand amp-hours, or a hundred thousand amp-hours? I can't imagin the cost, hassle and space rewquired for the latter, but it is what you would need to provide what you are asking about. I did a bit of search but couldn't find much- are there any 24 VDC appliances such as cooker/oven, fridge, AC and water heater you could recommend? In general, it is impracticle to use battery power for creating heat, i.e., stoves, ovens, water heaters, etc. It simply takes too much power for too long to make it practical to store. Nevermind the voltage, it is more of an issue of watt-hours. I know I can run standard items through power inverter but I would prefer not to do it for the sake of reliability/efficiency/cost. Using the inverter, you have the reliability and cost of just one thing: the inverter. After that, you can use very reliable and low cost 110 volt AC appliances. To find 24 volt anything is going to be expensive, and the bottom line is that DC motors are just not as reliable as AC motors, and high current/low voltage is harder to work with (and thus less reliable) than higher voltage/lower current. I want to go totally electric (no gas) Then run your generator when you need the power, and use the batteries for the small stuff. A reasonable battery bank can run your lights, refrigerator, and through an inverter you can run small appliances (such as a blender or short use of the microwave), TV, stereo, computers, etc. When looking for 24 volt equipment, take a look at commercial and "mega yacht" sources. Lights shouldn't be a problem, but you may find that electronics are scarce and very expensive. Since your battery bank is most likely made up of a number of batteries in series, you could tap off a 12 volt line and have both a 12 volt and 24 volt system. Use the 24 volts for the higher wattage stuff, such as the inverter, windlass and lights. Use the 12 volts for the electronics, such as depth finders, VHF, etc. Run the stove, water heater, and air conditioning off the generator. Rod McInnis |
