A greenhouse vegetable farm in southern Thailand is located in a rural area with unstable public power grid coverage. Frequent power outages and voltage fluctuations often lead to the failure of temperature control, irrigation and light supplement equipment, resulting in poor growth of vegetables, reduced yield and serious economic losses. The customer needs a stable off-grid power supply solution that can meet the high-precision power demand of greenhouse planting and realize energy saving and environmental protection.
Location/Time: Southern Thailand, October 2024
Configuration: PCS: 180kW, BAT: 540kWh, PV: 150kW, Backup UPS: 50kW
Load: Greenhouse temperature control air conditioners, drip irrigation systems, LED light supplement lamps, soil humidity sensors, farm office and living electricity
Operating environment: Tropical area, high temperature, high humidity, abundant rainfall, strong sunshine
Operating modes: Off-grid operation, solar energy priority, energy storage system for stable power output and peak regulation, UPS for emergency power supply of precision equipment (such as sensors and light supplement lamps) to avoid equipment damage caused by sudden power outages.
The system adopts waterproof, moisture-proof and corrosion-resistant design, which is suitable for the high-humidity environment of greenhouses. It is equipped with an intelligent energy management platform, which can monitor the power generation, energy storage and load operation in real time, and adjust the power supply according to the growth needs of vegetables (such as increasing light supplement power in cloudy days and adjusting temperature control power in high temperature periods).
Since the system was put into operation, there has been no power outage affecting production. The energy cost of the greenhouse has been reduced by 45% annually, the vegetable yield has increased by 20%, and the quality of vegetables has been significantly improved. This green energy solution has not only solved the power supply problem of the greenhouse farm but also promoted the sustainable development of ecological planting.
