    Wow. 3000/12 = 250 Amp hour.

    My car uses a 50 amp hour battery.

    Even my tractor only uses a 180 amp hour battery.

    Your typical car must be an electric vehicle or something similar.

    I wish that the people asking "real world" questions had some experience with the real world firstly.

    3 kw * hr

    -> 3000 watts * 1 hr

    -> 3000/24 w * 24 hr ( 125 W * 24 hr)

    or

    3000 * 60 W * 1/60 hr ( 180000W or 180 kw )
