Working Principle

1. Photoelectric Conversion: Solar panels absorb photon energy to generate direct current (DC) via the photovoltaic effect.

2. Charging Control: The controller monitors voltage and current to adjust the charging process, ensuring battery safety.

3. Energy Storage: Batteries store electrical energy as chemical energy and reverse the process when needed.

4. Inversion and Output: An inverter transforms DC power into standard AC power, regulating quality to meet grid standards.

5. Load Power Supply: The system dynamically balances power supply to meet real-time electrical load requirements.
