CD Power partnered with Medical Santo in Luganville, Santo, Vanuatu to deliver a fully off-grid power solution for a vital healthcare facility. With an unreliable local grid and expanding energy needs, the facility required a resilient and sustainable system to support critical medical services in a remote, tropical environment.

Challenges

1. Unreliable Grid Power

Frequent outages and voltage instability from the local grid threatened the operation of vital equipment like X-ray machines and medical refrigeration.

2. Harsh Environmental Conditions

High heat, tropical humidity, and exposure to cyclones made energy system performance and durability a major concern.

3. Continuous Power Demand for Critical Healthcare

Medical Santo required uninterrupted power 24/7, especially for life-saving equipment and refrigerated medicine storage.

4. Maintenance Accessibility

Limited technical support on the island made ease of maintenance and component replacement critical.

Solutions

Customised Stand-Alone Power System (SPS36)

CD Power designed and delivered a PowerCore SPS36, a modular system combining solar PV, lithium battery storage, advanced inverters, and a backup generator.

Key Components:

• 15 kW Solar PV Array – Harvests daytime solar energy, reducing generator reliance.
• 55 kWh Lithium Iron Phosphate Battery – Actively cooled, ideal for tropical climates, stores energy for night use.
• CE+T Sierra Inverters (36 kVA) – Hot-swappable modules provide clean voltage for sensitive medical devices and simplify on-site repairs.
• Backup Generator – Adds resilience in severe weather and emergencies.

Key Outcomes & Benefits

100% Power Reliability

• Enables uninterrupted operation of medical services, including around the clock use of X-ray and refrigeration equipment.

Disaster Resilience

• System withstands cyclones and seismic events, ensuring healthcare continuity in crises.

Cost Efficiency

• Significant reduction in operating costs by removing dependence on unreliable and expensive grid electricity.

Environmental Impact

• Solar-first design cuts fossil fuel use and lowers the facility’s carbon footprint.

Simplified Maintenance

• Hot-swappable inverter design allows for fast, on-site repairs without needing full system shutdowns.

Conclusion

CD Power’s PowerCore SPS36 has empowered Medical Santo with reliable, sustainable energy, transforming how remote healthcare can be delivered in the Pacific Islands. The project not only supports medical resilience but also serves as a scalable model for off-grid energy systems across similar regions.

At CD Power, we are proud to support critical services and contribute to the well-being of the Luganville community through dependable clean energy.
