Answer 1

12 volt inverters are a great thing for powering SMALL AC devices such as a computer or TV set. However the drawback is the level of DC current required at 12 volts.

If we assume a 100% efficient inverter going from 12 volts DC to 240 volts AC then the required DC current will be 20 times the required AC current. In other words, for every amp of AC output you will require 20 amps of DC input at 100% efficiency. Inverters simply are not practical for AC appliances which have high power consumption.
