Case Background
Qamar Hospital, located in Azamgarh, Uttar Pradesh, serves as an important healthcare facility where continuous power availability is essential for daily medical operations. To improve power reliability and ensure uninterrupted operation of critical equipment, the hospital deployed a Sunways hybrid energy storage solution based on parallel hybrid inverters and battery storage.
The system provides stable backup power during grid outages and voltage fluctuations, helping the hospital maintain reliable operation while reducing dependence on conventional backup generators.
Challenges
Reliable Power Is Critical for Healthcare Facilities
Hospitals require uninterrupted electricity to support essential medical equipment, including operating rooms, intensive care units (ICUs), laboratory systems, imaging equipment and hospital information systems.
However, the project site faced several challenges:
Frequent Grid Fluctuations
The local grid experiences voltage instability and power quality issues, especially during peak demand periods.
Critical Loads Cannot Tolerate Power Interruptions
Even short-term power interruptions can affect medical procedures, equipment performance and patient safety.
Conventional Backup Systems Have Limitations
Traditional diesel generators often involve delayed startup, high operating costs and ongoing maintenance requirements, making them less suitable for frequent power disturbances.
Sunways Solution
Parallel Hybrid Inverter System for Continuous Power Supply
To address the hospital’s power reliability requirements, Sunways designed a hybrid energy storage solution featuring parallel inverter operation and intelligent energy management.
System Configuration
- 2 × Sunways STH-8KTL-LS Hybrid Inverters
- Parallel Operation Mode
- Master-Slave Configuration
- Single Bus Bar Battery Connection
- Battery Energy Storage Integration
- Automatic Backup Power Switching
The parallel architecture enables intelligent load sharing between the two hybrid inverters while increasing system capacity and redundancy. During grid failures or voltage fluctuations, the battery storage system works seamlessly with the hybrid inverters to provide stable and uninterrupted power to critical hospital loads.
Solution Highlights
Parallel Hybrid Architecture
Dual hybrid inverters operate in parallel, increasing system reliability, flexibility and power availability for critical applications.
Intelligent Load Sharing
The master-slave control structure automatically balances power output between inverters, ensuring efficient system operation.
Reliable Backup During Grid Failure
When utility power is unavailable, the system automatically supplies backup power to critical hospital equipment.
Stable Output During Grid Fluctuations
The hybrid system maintains stable voltage and power quality, protecting sensitive medical equipment from grid instability.
Scalable Design for Future Expansion
The architecture allows future system expansion to accommodate growing energy demands.
