Can you get a 12v power inverter to work on a 24v battery?

Question

M992a2.... Was in a hurry to get an inverter and bought a 12v instead of a 24v

Answer 1

where did you get a 24 v battery ? most 24 v battery packs are made using two .12 v batterires. so if yours is like that , you could hook it up to just one of the batteries.



but the answer is no , you will have to return the inverter if you have a 24 v battery.





edit ,, Calli ,, you are so so so wrong .. 24 v input on a 12 v inverter will last about 2 seconds before it blows it .

Also , those old people 24 v mobility scoooters and kids scooters use two 12 volts batts in series for 24 volts like i said , not a 24 v batt ;(

Plus , stepping it down would just lose MORE power in the conversion = less battery life ;(



just like my 36 volt bicycle motor use three 12v batts in series.

Answer 2

Power Inverter 24v

Answer 3

Double your pleasure, double your fun with double mint, double mint, double mint gum! You'll get 240VAC if it works. These solid state sinusoidal wave form generators are picky. I imagine that it would work, but I don't know what you'd run with it other than a 240-120 step-down transformer to bring the voltage to 120VAC. Where you found a 24VDC battery is anyone's guess, it's a fairly rare bear used mostly for "scooters" (those things old people ride around on if they have mobility problems).



Get the specs on the inverter and see what max VDC input is. At least find out if it will blow a fuse or not. I'll give you an example. I have an inverter whose max input VDC is 240 at 867 ADC. While I'd be fine at 24VDC, it wouldn't run (well, it wouldn't run much). Get an in-line fuse and a DC-DC converter. It's lots cheaper to step down the DC side than the AC side.



I could be very wrong and your inverter could have shunts in it for just such a situation. I know quite a few inverters that will take a wide range of VDC inputs and still output 120VAC (VAC output isn't coupled to VDC input). It's going to depend upon your inverter's specs.



Use an in-line fuse and hook it up. See what you get.

Answer 4

I wouldn't recommend it.



Keep in mind that power = E^2 / R so whatever the input load (i.e. the "R") is for 12 volts, will be the same for 24 volts, but the power will be FOUR times that. Most likely the solid state switches and/or the step-up transformer windings will not be able to handle that much power.
