How It Works?

1. Daytime Solar Power Generation
During daylight hours, rooftop solar panels generate clean electricity.
Solar energy directly powers store operations
Excess electricity charges the battery system
Reduces electricity purchased from the grid
2. Peak Hour Energy Optimization
When electricity prices increase during peak hours:
The ESS automatically discharges stored solar energy
Reduces peak electricity consumption
Helps businesses save on electricity costs
3. Backup Power Protection
During grid outages:
The system automatically switches to backup mode to maintain power supply for critical equipment:
✓ Refrigerators & Freezers
✓ Lighting Systems
✓ POS Systems
✓ Security Cameras
✓ Communication Equipment
Ensuring continuous business operation without interruption.
