12v to 230v

That inverter was made for The Philippines where power Mosfets were not available.
Its output is a square-wave that most electronic products cannot use.
In the Philippines it powers incandescent lights and fluorescent tube lights and TVs that have a multi-voltage power supply.
Its output voltage drops as the battery voltage runs down.

The latest version of that inverter uses a zener diode to protect its Cmos IC.
Here is the latest version:

I saw your name on the schematic I posted, so I assumed it was okay...

One question that comes to my mind. How are the transistors mounted? ON pwb with heatsinks or stand alone heatsinks offboard with lots of wiring involved?

All collectors of the transistors on each side connect to one transformer wire. So I would bolt all transistors on one side to one heatsink without insulators and insulate the mounting of the heatsink from the metal chassis. Do the same on the other side with its own heatsink.
If something shorts one heatsink to the other heatsink then there will be huge sparks.
