Here is the simple inverter circuit below is a simple circuit diagram of a CD4047 Push Pull inverter that uses only a few components. It can provide AC power of 100W to 150W with 10V to 12V battery and center tape transformer (12V-0V-12V, 5A).

The integrated circuit (IC) CD4047 is connected as an astable multivibrator. The two oscillating outputs are out of phase, the 50K variable resistor determines the oscillation frequency. Power MOSFETs (IRFZ44) amplify each half of the AC voltage produced by the oscillator into an output power transformer that steps up the voltage from 12V DC to 230V AC.

However, you can increase the output power up to 1000W or more by adding more power MOSFETs in parallel, a larger power transformer, and a larger battery power bank.
