Applications and Benefits
The primary application of Schneider Electric solar pump inverters is in agriculture and irrigation, where they are used to deliver water to crops, greenhouses, and orchards. In such systems, a typical setup consists of a solar array, a Schneider inverter, and a submersible or surface pump. By eliminating the need for diesel fuel, operating costs are drastically reduced, often allowing the system to pay for itself within two to three years. Moreover, solar pumping reduces carbon emissions, supporting corporate and governmental sustainability goal
Remote diagnostics are facilitated through Schneider Electric’s EcoStruxure platform, which connects the inverter to cloud analytics. Maintenance teams can receive alerts about anomalies, such as low insulation resistance or abnormal DC voltage, enabling proactive maintenance. This is a significant advantage over conventional pump controllers that require on-site inspection. The long lifespan of the drive components, coupled with a global network of service centers, provides further assurance of operational continuit
It is also worthwhile to note that the price of solar pump inverters in general, including Leonics models, has been trending downward over the past decade due to advancements in semiconductor technology (such as the use of SiC MOSFETs) and increased market competition. However, the fluctuation of the Thai Baht and the global supply chain for electronic components can cause short-term price adjustments. Therefore, prospective buyers are advised to request a current quotation from multiple authorized Leonics distributors or their official Thai website. Some government subsidies or promotional discounts from the provincial electricity authority may also be available, which could reduce the effective price for agricultural users.
Introduction
Schneider Electric, a global leader in energy management and automation, has developed a comprehensive range of solar pump inverters designed to address the growing demand for sustainable, off-grid water pumping solutions. These devices convert direct current (DC) generated by photovoltaic (PV) panels into alternating current (AC) to drive standard three-phase pumps, while maximizing energy harvest and ensuring reliable operation in remote environments. Solar pumping inverters, particularly those from Schneider Electric’s Altivar Solar series, have become pivotal in agricultural irrigation, rural water supply, and livestock management, offering a cost-effective alternative to diesel-powered systems. This report examines the technical attributes, operational benefits, and applications of Schneider Electric’s solar pump inverters, highlighting their role in advancing solar-powered water infrastructur
Efficiency and Energy Management
Energy efficiency is a central design criterion for Schneider Electric solar pump inverters. The drives employ modern semiconductor technology, such as IGBTs (Insulated Gate Bipolar Transistors), and optimized control algorithms that maintain efficiency above 98% during conversion. This minimizes energy loss, allowing more of the solar-generated power to be used for pumping. Furthermore, the inverters can integrate a hybrid energy management function: when solar energy is insufficient, they can seamlessly switch to an AC backup source, such as the grid or a diesel generator, ensuring uninterrupted water supply. This “auto restart” capability after a power outage or low-light event requires no manual intervention, making the system fully autonomou
However, there are notable limitations. The processing speed of standard Arduino boards, typically 16 MHz, may limit the achievable PWM carrier frequency and the resolution of real-time control. At higher switching frequencies, the microcontroller can struggle to compute 3-phase SPWM and MPPT simultaneously. This can lead to increased harmonic distortion, causing heat losses in the motor. To mitigate this, dedicated PWM timers and shift registers can be used, but that adds complexity. Additionally, the power stage itself requires careful design regarding gate drive isolation, snubbers, and thermal management. The Arduino’s low-voltage logic (5V) cannot directly switch high-power transistors, making gate driver integration mandatory. These challenges require a solid understanding of both electronics and programming.
From an application standpoint, INVT solar pump inverters are used in a wide variety of sectors. In agriculture, they power irrigation pumps that supply water to crops, gardens, and greenhouses, reducing dependence on costly diesel fuel. In rural water supply, they lift water from wells and boreholes to community storage tanks.

In aquaculture, they maintain water circulation and oxygen levels in fish farms. In public works, they support fountains, swimming pools, and sewage treatment plants. Because solar pumping systems are modular, they can be easily scaled up by adding more PV panels and inverters in parallel, offering a flexible solution for both smallholder farms and large agribusinesses.
