As India accelerates its renewable energy transition, the role of power infrastructure components such as transformers, inverters, and grid interface systems has become increasingly critical. While solar generation capacity continues to grow, ensuring grid stability, power quality, and efficient energy conversion remains essential for the long-term reliability of renewable energy systems. At Intersolar India 2026, several companies showcased technologies designed to strengthen the renewable energy ecosystem. Among them was Volta Green Energy Pvt. Ltd., a company specializing in transformers, inverters, and power electronics solutions for solar and wind applications.
During the event, Shweta Kumari from The Battery Magazine spoke with Sumit Kumar Mistry, General Manager – Solar Division at Volta Green Energy Pvt. Ltd., to understand how the company is supporting India’s renewable energy infrastructure through advanced transformer and inverter technologies.
How has your experience been at Intersolar 2026 so far?
The experience at Intersolar 2026 has been positive. Events like this bring together industry stakeholders, technology providers, and project developers under one platform, which helps facilitate meaningful discussions around renewable energy technologies.
At Volta Green Energy, we have been working in the electrical industry for more than two decades, and participating in such exhibitions allows us to showcase our solutions while interacting with EPC companies, solar developers, and integrators from across the sector.
What products and solutions is Volta showcasing at the exhibition this year?
At this exhibition, we are showcasing our range of on-grid solar inverters and transformer solutions designed for renewable energy applications.
Our on-grid inverter portfolio ranges from 2 kW to 150 kW, catering to both residential and industrial segments. In addition, we provide transformer solutions specifically designed for solar inverter duty and wind inverter duty applications.
We also manufacture dry-type transformers and auxiliary transformers, widely used in solar power projects, including installations under government initiatives such as the KUSUM scheme.
Our solutions are designed to support solar developers, EPC contractors, and renewable project integrators, providing high efficiency along with strong technical and service support.
Transformers play a crucial role in grid stability and solar plant integration. How do your solutions address challenges such as harmonics and weak grid conditions?
One of the key technical challenges in solar plants is the conversion of DC power generated by solar panels into AC power suitable for grid integration. During this process, issues such as harmonics and grid instability can arise.
To address these challenges, our transformers are designed with high insulation levels and optimized K-factor ratings, enabling effective management of harmonic currents generated by inverter-based systems.
Additionally, we incorporate enhanced protection mechanisms to ensure both grid stability and equipment safety during operation. These design features significantly improve the overall reliability and lifespan of the system.
With battery energy storage systems gaining traction, how do you see your solutions evolving to support energy storage and microgrid applications?
Energy storage is emerging as a critical segment in India’s energy market. Battery Energy Storage Systems (BESS) involve rapid charging and discharging cycles, creating new technical requirements for power electronics and grid interface equipment.
To address these evolving needs, we are developing integrated solutions combining Power Conversion Systems (PCS) with Medium Voltage (MV) transformer stations.
In these systems, the PCS manages battery charging and discharging, while the transformer station facilitates grid integration. These solutions are being designed as compact, containerized systems, enabling faster deployment and operational efficiency.
Such integrated PCS–MV station solutions will support both solar-charged battery systems and grid-connected energy storage applications.
What kind of feedback are you receiving from EPC contractors and solar integrators regarding transformer solutions?
In the past, many projects relied on standardized equipment configurations. However, the trend in recent years has shifted toward customized solutions tailored to specific project requirements.
EPC contractors and system integrators increasingly require transformers that can address site-specific conditions, such as harmonic distortion levels, space constraints, or particular power ratings.
At Volta Green Energy, we work closely with project partners to provide customized transformer designs, ensuring that the equipment meets the exact operational and performance requirements of each installation.
Are there plans to expand into additional power electronics or storage-related components in the near future?
Yes, we are actively expanding our product portfolio. As mentioned earlier, we are developing PCS-integrated medium voltage stations specifically for battery energy storage systems.
These solutions will support both AC-side and DC-side battery charging applications, enabling seamless integration between solar generation, battery storage, and the grid.
We expect to introduce these solutions within the next five to six months as part of our strategic expansion into the energy storage ecosystem.
Looking ahead to 2030, how do you envision the future of Volta Green Energy in the renewable energy landscape?
Over the next five years, we plan to scale our product portfolio and expand into international markets.
We are exploring opportunities in African and European markets, where demand for renewable energy infrastructure is also growing rapidly.
At the same time, we remain committed to strengthening India’s power infrastructure. As renewable energy generation increases, reliable grid infrastructure will become even more important.
Our long-term vision is to support both India’s domestic energy transition and global renewable energy markets through high-quality transformer and inverter technologies.
