Product Description

Working Principle of Off-Grid Solar Power Generation System

1. Photoelectric ConversionWhen sunlight irradiates solar panels, semiconductor materials absorb photon energy, generating electric current (DC).
2. Charging ControlThe controller monitors voltage and current, adjusting the charging process to ensure safety and prevent overcharging.
3. Energy StorageThe battery converts electrical energy into chemical energy for storage, reversing the process when sunlight is insufficient.
4. Inversion and OutputAn inverter transforms DC power from the battery into standard AC power, regulating quality to meet requirements.
5. Load Power SupplyAC power is transmitted to various loads, balancing and stabilizing supply based on real-time requirements.
