Guess what?
A 1500W inverter will use 1800W from a 12V battery.
Then the 12V battery's current will be 1800/12= 150A and it will boil then blow up unless it is as big as your car.

Use a 12V inverter if your load is only 100W.

Thats a lie, it all depends on how much load you connect. I have always made those types of inverters with 1000watts to 2000watts and i use them to power school lights of 40watts and about 45 in number and it has always worked well. The two 200Ah batteries that i used have never boiled as you say

We have reliable electricity.
You have huge 12V batteries.

Most Big 12V batteries here are 80Ah, not the huge 200Ah batteries that you double to get 400Ah.
A 80Ah battery boils when it has a 150A load.
