Newer designed inverters
Anyone who has spent some time on eBay has seen the incredibly low priced Chinese inverters. Some of the spec are out right lies (5000W output using a 12V battery ? Right. Sure.) But there is a sp...

I consider a couple of things to be the "newer" tech- the basic is simply doing the actual inversion at a very high frequency, so you can use small transformers- chop the 12 volts at 10 kHz, ...
You are few years behind. 40kHz is the low end now a days.

You need to exceed the peak-to-peak voltage of 120V AC, so at least 270VDC.

Again, your have to get up to date. Generate a 50/60Hz sine wave and feed it to a Class D amplifier biased with your 270VDC.

100% correct ! I have glossed over all the safety factors. There is a certain amount of built in over/under voltage and current sensing but you really need a CPU to "over see" things.
