# Hotel PV-Diesel-Storage Microgrid Solution Provide stable, economical, and green power assurance for island and remote hotels, enhancing the guest experience. Solution Overview Provide PV-storage-diesel microgrids for island resorts, eco-hotels and remote camps, balancing stable power supply, cost and green image. Key Points Integrated PV-storage-diesel for stable power supply to island/remote hotels STS ensures seamless uninterruptible power for 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 Applicable Scenarios and Challenges Island hotels rely on diesel, with high electricity prices, and noise and emissions affecting the experience; load is high during peak tourist seasons, 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 grid/diesel generator and microgrid to ensure uninterruptible power for guest rooms. **Battery Energy Storage System (BESS)**: Peaks shaving and valley filling, smoothing evening peaks, reducing diesel generator operating hours. **Energy Management System (EMS)**: Dispatches based on occupancy rates and weather forecasts to maximize green power. **Microgrid Power Switchgear (MPS)**: Low-noise AC cabinet, suitable for hotel environments. Core Value Reduce diesel and electricity expenses Quiet and green, enhancing guest experience and brand Uninterruptible power for critical loads, avoiding negative reviews Visualized management, convenient for hotel operations Typical Applications Suitable for island resorts, eco-camps and remote scenic area hotels. Delivery and Support VGRID POWER (VGRID) provides integrated delivery from on-site assessment, system design, core equipment manufacturing (PCS/STS/BESS/MPS) to commissioning and remote O&M. Welcome to contact us for customized solutions and quotations. ## Will a hotel microgrid affect the guest experience? No. STS seamless switching ensures uninterrupted power to guest rooms, while BESS and low-noise design reduce diesel noise and emissions. ## What is the approximate payback period? Hotels on high-electricity-price islands typically recover the investment in 3–5 years, depending on diesel prices and solar resources. ## How does a hotel microgrid coordinate with the municipal grid? It can operate grid-connected and prioritize solar power. During a power 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 a backup, and the EMS only starts them when solar/storage is insufficient.
