Every time you convert the voltage, you are losing energy as heat. You will also want to upgrade the alternator, as most modern cars only come equipped with alternators capable of sustaining the electronics placed by the manufacturer.You might look at a solution involving only a single voltage change, from 12 to 144. No since in inverting and then rectifieing the power, when you can just invert it once and be done with the whole mess. Yes, it will work, but at a significantly low efficiency.
