The EGS002 is a single-chip inverter controller that is widely used in small-scale inverter applications. Here are some general datasheet for the EGS002:
- Input voltage range: +15V - +20V DC and +5V
- Output voltage range: 110V or 220V AC (depending on the transformer used)
- Output frequency: 50Hz or 60Hz (depending on the configuration of the chip)
- Maximum output power: approximately 300W
- PWM frequency: 16kHz
- Over-current protection: Yes
- Over-voltage protection: Yes
- Under-voltage protection: Yes
- Over-temperature protection: Yes
- Standby power consumption: less than 1W
The EGS002 is designed to work with a center-tapped transformer, and can generate a pure sine wave output waveform using a combination of PWM and SPWM modulation techniques.
It has a low standby power consumption, high efficiency, and comprehensive protection features that make it suitable for small-scale renewable energy applications.
Note that these specifications are general and can vary depending on the specific implementation of the EGS002 inverter board.
It's always best to consult the datasheet or technical specifications provided by the supplier or manufacturer for the specific board you are working with.

How to Connect
Connecting the EGS002 board to external MOSFETs is feasible, however it needs a few improvements to the board and good knowledge of the circuit design. Listed below are the reccommended methods to connect the EGS002 board to external MOSFETs:
Get rid of the present MOSFETs from the EGS002 board. This would call for desoldering the MOSFETs from the board and eliminating any associated elements (for example gate resistors and diodes).
Choose the external MOSFETs that you would like to work with. Ensure these are rated for the voltage and current specifications of your application.
Connect the gate of each external MOSFET to the equivalent gate drive signal on the EGS002 board. The gate drive signals are generally named as "G" on the board.
Hook up the drain of each external MOSFET to the positive output of the center-tapped transformer. The positive output of the transformer is normally attached to the positive terminal of the output capacitor.
Hook up the source of each external MOSFET to the negative output of the center-tapped transformer. The negative output of the transformer is usually attached to the negative pin of the output capacitor.
Insert any essential elements to the circuit, for example gate resistors and diodes, to guarantee correct functioning of the MOSFETs.
Customize the control jumpers on the EGS002 board make it possible for external MOSFET functioning. This might demand modifying the jumper settings for the "EGS002/04" and "EGS002/05" pins on the board, along with setting up the "EGS002/01" jumper to "ext".
It is critical to remember that changing the EGS002 board in this manner could be complicated and necessitates a great knowledge of the circuit design. If you are not knowledgeable in electronics or inverter design, it's best to speak with an experienced person or work with a pre-built inverter board that actually contains external MOSFETs
