Smart Solar Irrigation Pump Controller

Agriculture is a vital part of many people’s lives, but rising water and energy costs make traditional irrigation systems, which rely on grid electricity or diesel generators, increasingly expensive. This has led to a growing demand for solar-powered alternatives and smart features to conserve energy and water.

Renesas offers a green energy system to meet this demand, providing an efficient and sustainable irrigation system applicable across various regions. By harnessing solar energy and utilizing the maximum power point tracking (MPPT) algorithm, the system maximizes energy efficiency and reduces grid reliance during peak cultivation seasons. The user-friendly interface allows for isolated, programmable control of irrigation schedules and motor speed, offering flexibility and precision for efficient and sustainable agricultural irrigation.

System Benefits​:

• Compatible with both AC and PMSM motors, using advanced variable frequency drive (VFD) and field-oriented control (FOC) techniques for optimal performance and cost-effectiveness in diverse agricultural applications.
• Utilizes an MCU with a floating point unit (FPU) for efficient single inverter control.
• Discrete IGBT-based design is cost-effective and thermally reliable.
• NB-IoT and Bluetooth^® Low Energy (LE) modules enable effective dynamic data acquisition and diagnostics.
• Solar pump controller emits zero greenhouse gases, reducing carbon footprint.
• Implements single shunt, leg shunt, and panel shunt for enhanced protection.
