Key Features of Photovoltaic Uninterruptible Power Supply System
- Leverages existing UPS rectifier, inverter and charge controller
- Low AH battery bank suffices for day-time use
- Battery/ PV array voltages are matched, but much lower than dc-link voltage when ac ON [but sufficient for inverter operation]
- Low-cost modular add-on controller [Smart Relay], based on linear relationship [irrespective of solar irradiance and ambient temperature] between PV array’s open circuit voltage, Voc, and its peak power voltage, Vmp:
- Automatically switches in the appropriate power source [PV array/ Utility]
- Minimizes power outage probability
- Maximizes expected solar power utilization
- Minimizes expected grid power utilization
- Minimizes expected life cycle costs [including capital amortization, battery replacement and system maintenance]
- Changes to the UPS to interface PV array and Smart Relay are simple and fail-safe
- Easy integration into Hybrid Systems [Wind/PV/Grid] for 24/7 operation
- Communications
- Defence electronics
- Video
- Audio
