A mountain residential villa in eastern Switzerland is located in a high-altitude area, where the public power grid is difficult to cover due to harsh terrain. The villa is used as a holiday home for residents, and the power supply needs to meet the needs of daily living, heating, and outdoor lighting. The original diesel power supply mode has high fuel costs, serious environmental pollution, and is inconvenient to transport fuel in winter. The customer needs a clean, stable, and low-maintenance off-grid power supply solution that can adapt to the high-altitude and cold environment.
Location/Time: Eastern Switzerland, October 2024
Configuration: PCS: 100kW, BAT: 300kWh, PV: 90kW, Backup Gas Generator: 70kW
