Hotel PV-Diesel-Storage Microgrid Solution
Summary: Stable, economical and green power supply for island and remote hotels, enhancing the guest experience.
Solution Overview
PV-storage-diesel microgrids for island resorts, eco-hotels and remote camps, balancing reliable power supply, cost and green branding.
Key Points
- Integrated PV, storage and diesel for stable power supply to island/remote hotels
- STS ensures seamless, uninterrupted power to guest rooms
- BESS and low-noise design reduce diesel noise and emissions
- Payback period of about 3–5 years for island hotels with high electricity prices
Application Scenarios and Challenges
Island hotels rely on diesel, with high electricity prices, noise and emissions affecting the guest experience; peak tourist season loads are high, and power supply reliability directly affects reputation.
VGRID System Composition
- Power Conversion System (PCS): flexibly dispatches PV/diesel/storage to support air conditioning, lighting and kitchen appliance loads.
- Static Transfer Switch (STS): switches between the grid/diesel generator and the microgrid, ensuring uninterrupted power to guest rooms.
- Battery Energy Storage System (BESS): performs peak shaving and valley filling, smooths the evening peak and reduces diesel generator operating hours.
- Energy Management System (EMS): dispatches based on occupancy rates and weather forecasts to maximize green power.
- Microgrid AC Cabinet (MPS): low-noise AC cabinet suited to hotel environments.
Core Value
- Reduces diesel and electricity costs
- Quiet and green, enhancing the guest experience and brand image
- Uninterrupted power for critical loads, avoiding negative reviews
- Visualized management for easier hotel operations
Typical Applications
Suitable for island resorts, eco-camps and remote scenic-area hotels.

FAQ
Will a hotel microgrid affect the guest experience?
No. STS seamless switching keeps guest rooms powered without interruption, while the BESS and low-noise design reduce diesel noise and emissions.
What is the approximate payback period?
For high-electricity-price island hotels, payback is typically 3–5 years, depending on diesel prices and solar irradiance.
How does a hotel microgrid work with the municipal grid?
In grid-connected operation it prioritizes solar power; during an outage the STS automatically switches to off-grid mode, with no noticeable impact on guests.
Do existing diesel generators need to be removed?
No. They can be retained as backup, and the EMS starts them only when solar and storage are insufficient.
