Working Principle of Off-Grid Solar System
1. Photoelectric Conversion

When sunlight irradiates solar panels, semiconductor materials absorb photon energy, generating electric current and converting solar energy into direct current (DC).

2. Charging Control

The DC power enters a controller that adjusts the charging process to the battery, ensuring safety and preventing overcharging.

3. Energy Storage

The battery stores electrical energy as chemical energy. When sunlight is insufficient, it converts chemical energy back into electrical energy.

4. Inversion and Output

An inverter transforms the DC power from the battery into standard alternating current (AC) for grid-standard requirements.

5. Load Power Supply

The AC power is transmitted to electrical loads, dynamically balancing supply according to real-time requirements.
