How does a step-up transformer, like the one used in a a battery-powered standby electrical system, not violate the Law of Conservation of energy when it changes 12V from a DC source to 110V of AC supply?
As a volt is essentialy the amount of energy (joules) used up by an electric charge, (coulombs) how does it make sense for a system to consume more energy than its input? Obviously, we have step-up transformers that work fine so we don't violate the Law of Conservation of Energy but I just dont get how this happens....

There is no violation since the power is constant
and conserved
If the voltage is higher, the current is smaller.
This principle is used for the transportation of electicity.
The voltage is very high but the current is very small.
Also, you have loss of energy in transformers, especially heating (Joule's losses)
PS :
You cannot connect directly your
