1. How does Eastman’s backward integration improve the quality and reliability of your grid-tied inverters?
The Grid Tie Inverters is a result of Eastman’s unwavering commitment to ‘Make in India’ and our vision of becoming a globally respected solar energy products manufacturer. Through backward integration, we manufacture critical components of the Grid Tie Inverter in-house at our advanced power electronics facility, ensuring superior quality and consistent performance.
Our strength lies in robust in-house R&D capabilities. From firmware development to system architecture, the Grid Tie Inverter is designed to meet the unique challenges of Indian C&I consumers—such as load variability, extreme weather conditions, and the demand for smart grid compatibility. This level of control enables us to maintain high-quality standards across every stage of production.
We operate four dedicated manufacturing facilities for power electronics components, maintaining the highest levels of quality and control. With technologies such as Injection Moulding, Surface Mount Technology, and Manual Insertion, We ensure customer needs are met for consistent supply of Solar Energy.
This seamless synergy between R&D and manufacturing empowers us to deliver reliable, feature-rich, and cost-effective solutions. We’re not just making inverters—we’re building solutions made for India and ready for the world.
2. In what ways is Eastman reducing import dependency and supporting “Make in India”?
Eastman today operates eight state-of-the-art manufacturing facilities across India, each designed with a focus on innovation, quality, and self-reliance. Out of these, one facility is dedicated exclusively to lithium battery production, where we manufacture batteries for E-Rickshaw, Residential Backup & Solar Storage applications.
Four of our facilities specialize in power electronics—covering home inverters, off-grid inverters, grid-tie inverters & E-Rickshaw Chargers. Here, backward integration plays a critical role, as we produce essential components like Cabinets, fans, and transformers in-house. Our Backward Integration facilities include Injection Moulding, Heat Sink Machining, Press Shop, Laser Cutting Machines for Cabinets, Inductor Manufacturing, and BOPET Sheet Manufacturing. This not only ensures consistency and quality but also reduces dependency on imports.
The remaining three facilities are focused on lead-acid battery manufacturing. Together, these eight facilities reflect our commitment to ‘Make in India’, creating resilient, integrated supply chains that support India’s clean energy transition.
3. How is indigenous technology helping you deliver cost-efficient and high-performance inverters?
Indigenous technology is at the heart of how we design and deliver cost-efficient, high-performance inverters. By developing core technologies in-house—whether it is advanced MPPT algorithms, IoT-enabled monitoring systems, or robust safety features—we are able to customize solutions for Indian and global grid conditions without relying on costly imports.
This not only reduces cost but also gives us the flexibility to innovate faster and address specific consumer needs in diverse markets. Indigenous R&D, combined with our backward integration in power electronics, allows us to achieve the right balance of performance, reliability, and affordability. Ultimately, it enables Eastman to offer world-class inverters that are ‘Made in India, for the World’—delivering long-term value to customers while supporting the country’s self-reliance in clean energy.
