Fuji Electric is stimulating energy transition with solar pump solutions

Fuji Electric inverters come equipped with True Maximum Power Point Tracking (MPPT) and Optimal Operating Point Calculation that ensures maximum energy harvest from solar panels even under changing irradiance and temperature.

With the clean energy transition, the agriculture industry is witnessing a rapid shift in the power landscape. The adoption of renewable energy, particularly solar power, is reshaping the way solar pump inverters are designed and deployed, especially for agricultural purposes. The solar pump solutions must ensure not only efficiency but also reliability under diverse field conditions. Palanisamy Lakshman from Fuji Electric India shares his views on the ongoing developments in the industry. Let us hear him.

How is Fuji Electric helping farmers maximise water output and energy efficiency, and what capacity expansions have been introduced recently for the solar pump inverter lineup?

Fuji Electric has engineered a Frenic Solar Pump Controller that addresses the evolving needs of the agriculture sector, where solar pumps are used under diverse field conditions. With installations across regions, our solutions are designed to maximise energy utilisation from solar PV panels through advanced Maximum Power Point Tracking (MPPT) and Optimal Operating Point Calculation. These functions ensure that the pumps consistently deliver water output even under fluctuating irradiance and temperature conditions, which makes them highly adaptable for farmers relying on renewable energy sources.

We have been steadily expanding our solar pump inverter lineup in India to meet the rising demand for higher-capacity and more reliable renewable pumping solutions. Building on the success of the FRENIC-Mini, designed for smaller pumps, the company recently introduced the FRENIC-Ace. This new model supports larger pump capacities and offers advanced control for more demanding irrigation needs. Apart from this, we have developed dedicated Water Drives FRENIC-AQUA with capacities ranging from 0.75 kW up to 710 kW. It integrates features such as built-in EMC filters, DC reactors and energy-saving functions. These innovations ensure broader coverage across small, medium and large pumping applications.

In essence, Fuji Electric’s solar pump solutions are enabling farmers and industries to harness renewable energy more effectively. It delivers sustainable water pumping that reduces dependency on fossil fuels and supports the clean energy transition in the country.

How has Fuji Electric improved local design and customisation capabilities, particularly in India, for its solar pump inverters?

Our philosophy of ‘In India, For India’ guides how we design and deliver solutions for the local market.

Complementing the product portfolio, we are also expanding our manufacturing and R&D operations in India. This will enable faster customisation, higher production capacity and better alignment with local field conditions. Together, these developments position Fuji Electric as a key enabler of the clean energy transition in the country through scalable and efficient solar pumping solutions.

We offer localised design and customisation, which ultimately help improve product resilience against heat, dust, and varied grid conditions. This also ensures faster service and support for rural communities.

Through these efforts, we remain committed to empowering the industry with reliable, efficient, and sustainable pumping solutions that enable farmers to harness solar energy effectively and contribute to the clean energy future of India.

Have there been any technological enhancements or accessory offerings like updated software, MPPT features or mode functions for solar pump inverters?

Yes, Fuji Electric has continuously enhanced its solar pump inverter technology with advanced features and smart functions designed for Indian field conditions. Our inverters now come equipped with True Maximum Power Point Tracking (MPPT) and Optimal Operating Point Calculation that ensures maximum energy harvest from solar panels even under changing irradiance and temperature. Functions like sudden irradiance change detection, dry pump protection and tank level monitoring safeguard pumps from damage and reduce downtime.

On the software and control side, features such as two sets of PID gains enable the system to respond flexibly to varying conditions. The low power function further alerts users to issues like dust accumulation on panels. We have also introduced remote monitoring through GSM/GPRS connectivity, which enables real-time tracking of performance, water flow and electrical parameters from a mobile or computer.

Together, these enhancements make Fuji Electric solar pump inverters more intelligent, reliable and farmer-friendly. This helps to maximise water availability while minimising maintenance and the low cost of ownership.
