Localizing the Heart of Solar

In the fast-evolving solar and power electronics industry, inverters form the backbone of every energy solution. Yet, what often goes neglected is the science behind how these inverters are built, especially the components that give them life from within.

This is where backward integration makes all the difference. By producing critical components in-house, companies gain better control over cost, quality, and innovation. At Eastman, we have taken this strategy a step further by building a fully integrated ecosystem in power electronics. The result? World-class inverters that are reliable, affordable, and proudly engineered in India.

Why Backward Integration is a Game Changer

Relying heavily on third-party suppliers often creates bottlenecks such as:

• Inconsistent product quality
• Delayed supply timelines
• Higher production costs
• Limited room for innovation and customization

Backward integration eliminates these hurdles. It enables manufacturers to maintain tighter control over design, ensure consistent quality, and manage costs effectively. For inverters where durability, safety, and efficiency are critical, this approach ensures product excellence from start to finish.

Eastman’s Backward Integration in Power Electronics

Eastman has invested extensively in developing in-house capabilities to manufacture the most crucial inverter components. This initiative not only enhances consistency but also accelerates product innovation and minimizes dependency on external vendors.

Our backward integration covers:

Printed Circuit Boards(PCB): Engineered for superior efficiency and reliability.
• Core: Developed in-house to meet strict electrical and magnetic standards.
• Heat Sink: Built for maximum heat dissipation and longer inverter lifespan.
• Transformer: Designed for stable power flow and voltage stability.
• Case: Durable and protective, ensuring resilience.
• Injection Molding: Delivering precision in structural components.
• Fan: Customized for efficient cooling and quiet performance.

By managing these key processes internally, Eastman ensures that every inverter delivers unmatched reliability, safety, and longevity.

Next-Gen Manufacturing Facilities

To support this model, Eastman operates four advanced manufacturing plants dedicated solely to power electronics. These facilities are equipped with:

• High-speed SMT lines for PCB production.
• CNC and thermal systems for transformers and heat sink fabrication.
• Robotic precision systems for molding and assembly
• Dedicated quality labs for raw material and final product testing

This state-of-the-art infrastructure allows Eastman to maintain control from raw materials to the final inverter.

Design. Develop. Deliver. All In-House.

1. Cost Efficiency: Lower costs through elimination of intermediaries without compromising quality.
2. Made in India: Driving the ‘Make in India’ vision by reducing import reliance and creating local opportunities.
3. Innovation Edge: In-house expertise fuels continuous improvement and product innovation.
4. Stringent Quality: Each stage undergoes rigorous checks, ensuring consistent performance and durability.

The Result? A Seamless Power Electronics Ecosystem

We believe quality begins at its source. Our decision to backward integrate across major inverter components is not just a strategy, it’s our commitment to innovation, reliability, and national pride. Every part of an Eastman inverter is designed with precision and purpose, it’s engineering confidence in every unit.
