Working Principle of Off-Grid Solar Power Generation System
1
Photoelectric Conversion: Internal semiconductor materials absorb photon energy through the photovoltaic effect, converting solar energy directly into DC current.
2
Charging Regulation: The controller monitors voltage and current to adjust the charging sequence, preventing overcharging.
3
Energy Storage: Electrical energy is transformed into chemical energy within batteries for long-term storage and reused when sunlight is insufficient.
4
Inversion: An inverter converts DC power into standard AC power, regulating voltage and frequency for grid compatibility.
5
Load Power Supply: AC power is distributed to electrical loads, balancing supply according to real-time requirements.
