India’s clean energy transition is entering a new phase—one defined by reliability, intelligence, and integration. As consumers and businesses demand power solutions that are not only sustainable but also seamless and dependable, the market is rapidly shifting toward smarter, more compact systems that deliver uninterrupted performance. This is where Eastman’s Solar Power Conditioning Unit (PCU - Off Grid Inverters) + Lithium Combo Systems are redefining expectations.

For decades, the solar industry has treated inverters and batteries as separate components. While the model worked, it created challenges: inconsistent product pairing, installation complexity, space constraints, and varying performance outputs. At Eastman, we recognised early that the next evolution in rooftop solar would require a unified approach—one where brains (control + intelligence) and power (advanced lithium storage) operate as a single, cohesive unit.

Our integrated Solar PCU + Lithium Solution is built precisely for this purpose. Designed, engineered, and rigorously tested at Eastman’s advanced facilities, this unified system combines three powerful technologies to deliver uninterrupted, efficient, and intelligent energy.

Smart Power Conditioning: Ensures maximum solar utilisation, intelligent grid prioritisation, and seamless load management, keeping your power stable, clean, and efficient at all times.
Advanced Lithium Battery Technology - Built with high-energy-density cells, long life cycles, and multi-layered safety protections, our Lithium batteries deliver faster charging, deeper discharges, and superior reliability.
Unified System Intelligence - Integrated intelligence enables optimised charging, real-time performance monitoring, and maximum power availability for every critical load.

Key Benefits

Zero Fumes, Zero Maintenance – Clean, silent, and hassle-free backup for homes and businesses
Eco-Friendly & Sustainable – Completely green solution with a 5-year comprehensive warranty
Uninterrupted Power Delivery – Solar + Lithium combo ensures extended backup with consistent performance.
Compact & Lightweight Design – Easy to install, easy to handle, and perfect for space-constrained locations

Our Solar PCU is manufactured at Eastman’s state-of-the-art Power Electronics Facility, where we emphasise Backward Integration for superior quality and long-term performance. The majority of the critical components are produced in-house, including the Front Bezel, Heat Sink, Core, and Transformer, ensuring unmatched reliability and control over every stage of manufacturing.

Complementing this, our Lithium Batteries are designed as Lead-Acid Replacement Solutions, manufactured at our dedicated Lithium Battery Facility. Built on advanced energy storage technology, they offer higher efficiency, longer life cycles, faster charging, and complete safety.

Where the Solar PCU + Lithium Combo Works Best

Residential Homes (Urban + Rural) - Ideal for households facing frequent power cuts or wanting to reduce dependence on the grid.

Small Commercial Shops & Offices - Perfect for retail stores, clinics, coaching centres, and small offices requiring clean and reliable backup power.
Healthcare Clinics, Pathology Labs & Pharmacies - Ensures uninterrupted power for sensitive diagnostic and medical equipment.
Educational Institutions & Coaching Centres - A dependable solution for schools and learning centres, especially in rural or high-temperature regions.
Rural & Remote Areas - Designed for locations with weak or no grid connectivity, enabling round-the-clock access to electricity.

What makes this integrated approach particularly relevant for India is the diversity of application needs. Homeowners seek reliability during power cuts. Small businesses demand a compact system that saves space and reduces downtime. Commercial users look for efficient energy management and lower operating costs. Eastman’s Solar PCU + Lithium combo delivers on all these fronts, strengthening India’s push toward decentralised, green energy.

Beyond convenience and performance, safety remains a cornerstone of our innovation. Every lithium module is engineered with multi-level protective circuitry, thermal safeguards, and robust enclosure design, ensuring dependable performance in varied climatic conditions.

As India’s renewable energy ambitions accelerate, integrated energy systems will play a pivotal role in shaping the next era of rooftop solar adoption. At Eastman, our mission is to empower this shift by building solutions that combine technological intelligence with dependable power-systems that simplify sustainable living, strengthen grid resilience, and ultimately, enable energy independence.

The rise of Solar PCU + Lithium combos is not just a technological evolution; it marks a shift in how consumers and businesses think about power. And we are proud to be at the forefront of this change.
