hi all
need help or direction on designing an inverter with 12V DC input and 120V AC output with 1500W your help is greatly apreciated |

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. |

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
