Solar Pump Inverter
Photovoltaic-Grid Complementary Water Pump Inverter
Product Features
• Dual-Power Intelligent Switching: Innovatively adopting a solar-first + grid-supplemented intelligent control strategy, the system uses 100% solar power to drive the water pump when sunlight is abundant, achieving "zero electricity cost" operation. When solar power is insufficient, the system automatically and seamlessly switches to grid power mode, ensuring continuous pumping on cloudy days and at night, completely solving the pain point of traditional solar water pumps being dependent on weather conditions.
• 99% Ultra-Efficient MPPT Algorithm: Equipped with a self-developed third-generation intelligent MPPT tracking engine, the system achieves a tracking efficiency of up to 99%, more than 40% higher than traditional solutions. By monitoring the voltage and current characteristics of the solar array in real time, the system dynamically adjusts the operating point to maximum power output, ensuring that every ray of sunlight is efficiently converted into pumping energy.
• Intelligent Load Matching Technology: Built-in pump characteristic curve learning algorithm automatically adapts to different types of water pumps such as centrifugal pumps, submersible pumps, and screw pumps, optimizing motor starting current, reducing mechanical shock, and extending equipment life.

Application Scenarios and Advantages
• Farmland Irrigation: In sunny regions such as Yunnan and Xinjiang, it has been successfully applied to large-scale farmland irrigation projects exceeding 200 mu (approximately 33 acres), saving over 70% in costs and reducing carbon emissions by 90% compared to traditional diesel engine irrigation.
• Water Supply in Remote Mountainous Areas: In remote mountainous areas without power grid coverage, a photovoltaic + grid power complementary model solves the drinking water and livestock water problems for villagers, improving their quality of life.
• Pasture and Grassland Irrigation: In pastoral areas such as Inner Mongolia and Qinghai, it ensures grassland irrigation and livestock drinking water needs, promotes grassland-livestock balance, and supports the development of ecological animal husbandry.
• Energy Saving and Environmental Protection Advantages: The system's total life-cycle carbon emissions are only 1/5 of those of traditional diesel engine water pumps, meeting the "dual carbon" target requirements.
