This is your third post without defining the hold up time required. You need to specify with no if's, and's, or but's three things. The voltage you need to maintain (a maximum and minimum allowable value) the current being drawn, and thirdly and most important the time you need to draw that power over. "A long period of time" is not an exceptable value in electronics =) Number of seconds would be much better. 24 volts (20-30 volts) at 10 amps you will at BEST be able to get a couple of seconds (1-3) and that's with a capacitor bank more expensive than a battery bank able to do the same thing over at least a half hour or better..
IanP said:I still think that for applications like yours (windmill) batteries are much better option than capacitors, even, if you need energy just for a "short" period of time (how short???) ..
Here are examples:
A 1F (1,000,000µF) 12V capacitor will light a bulb for about 15 whole SECONDS!!!
(not mentioning the physical size of 1Farad capacitor) ..
A 4700µF would likely discharge so quickly that it would barely cause the light to flicker ..
