In a recent interview with Renewable Watch, Divya Prakash Choraria, Chief Executive Officer and Co-Founder of WattPower, discussed the company’s rapid growth journey since its inception in 2022, its core focus on high-quality, India-designed solar inverters, and its vision to become a smart energy solutions provider by 2030. He highlighted WattPower’s commitment to domestic manufacturing, artificial intelligence (AI)-driven digitalisation and grid-resilient technology, as well as its plans to expand into international markets, particularly Europe.
Please provide a brief overview of WattPower and its journey so far. What are the key service offerings?
Founded in 2022 by Divya Prakash Choraria, WattPower was born out of a clear vision: to address a critical gap in India’s solar market – the absence of high-quality, domestically designed inverters. While inverters represent only a small fraction of a solar project’s overall cost, they are the heart of the system. In just three years, WattPower has achieved remarkable growth, selling approximately 15 GW of inverters and managing an installed base of 22 GW. Proudly made in India, our products are engineered for durability and long-term performance, backed by rigorous research and development, precision manufacturing and uncompromising quality standards.
Our core offerings include high-efficiency string inverters like the WP330KTL, smart monitoring systems such as the SmartACU2000D, and advanced safety features like fast fault-response switches, connector temperature monitoring and self-cleaning fans. We also support customers throughout the full lifecycle, including warranty management and responsible e-waste handling.
How is WattPower aligning its inverter and hybrid offerings to support large-scale solar-plus-storage projects?
Our inverters are storage-ready and can handle energy from solar, wind and battery systems. They respond instantly to grid fluctuations and storage charge/discharge signals, ensuring smooth operation. While we do not manufacture batteries ourselves; our systems are designed to integrate with storage solutions seamlessly, helping operators maximise energy yield, maintain grid stability and minimise downtime.
How is WattPower integrating digitalisation, AI, or internet of things (IoT) into its products?
At WattPower, digitalisation and AI are at the heart of our approach. Our inverters use intelligent algorithms to sync with the grid in milliseconds, dynamically respond to changing conditions and optimise performance across multiple units. We are also exploring cloud-based monitoring, IoT-enabled controls and autonomous plant operations, enabling solar plants to run smarter, safer and with minimal manual intervention. These technologies support predictive maintenance, real-time performance analytics and operational efficiency, ensuring maximum energy output and reliability.
Beyond India, do you see WattPower expanding into international markets? If yes, which regions are of immediate interest?
Yes, international expansion is a key part of WattPower’s next growth phase. We are actively preparing to enter European markets, where there is a strong policy push toward clean energy adoption and a mature ecosystem for solar and storage integration.
How do current Indian policies on solar manufacturing and localisation impact your business?
India’s push for self-reliance in manufacturing, particularly in the solar sector, has created a highly supportive environment for companies like ours. Initiatives such as the production-linked incentive scheme, coupled with rationalisation of imports, are designed to strengthen domestic manufacturing capabilities and build a resilient solar supply chain. These policies not only encourage local production but also incentivise innovation and quality in homegrown solutions.
At WattPower, our India-designed inverters are perfectly aligned with vision. Our large-scale manufacturing facility in Chennai enables us to produce high-quality inverters at scale while maintaining cost-effectiveness. This ensures that our products are not only reliable and durable but also competitively priced for the Indian market. Moreover, localisation helps us respond quickly to customer needs, streamline supply chains, and contribute to the broader goal of energy self-sufficiency in India.
Where do you see WattPower’s product portfolio by 2030, will it expand beyond PV inverters into broader energy management systems?
By 2030, WattPower aims to evolve into a complete smart energy solutions provider. Beyond PV inverters, we plan to venture into the battery energy storage segment and industrial electric vehicle charging solutions, leveraging our core expertise in power electronics. The goal is to build an integrated platform that connects generation, storage and mobility – delivering reliable, efficient and future-ready energy systems.
