Dear Car Talk:
Here’s a new car topic: Inverters on cars for power outages.
The inverters I am talking about are ones attached to car batteries, I’d rather avoid the cigarette lighter plug-ins for safety.
With all the power outages in California lately, I was able to utilize my motor home’s generator to keep a two fridges & one commercial freezer in proper temperature ranges. But having our motor home is not always convenient for us. So, what about hooking up a sine wave inverter to the car battery for household 110V power?
I realize that the engine needs to run for a period of time to keep the battery from depleting, but just what voltage/wattage can be obtained to stay within the limits of the car battery/alternator without mishap to the car’s electrical system? And just how many appliances can be run at one time with such a generator? I realize that peak wattage is a consideration as well for motor startups.
For instance, a typical a 725-watt refrigerator draws 725/120 = 6 amps.
Any thoughts or suggestions on this?
