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.
