Gronsol Launches Advanced Solar Inverter Manufacturing Plant in Surat with 12,000 Units Monthly Capacity

Gujarat-based solar inverter and lithium-ion battery manufacturer Gronsol has commissioned a new, state-of-the-art solar inverter manufacturing facility in Surat, Gujarat, marking a significant step in its expansion and localisation strategy.

In the first phase, the facility has an installed production capacity of around 12,000 inverters per month, aimed at meeting India’s rising demand across the residential, commercial, and industrial solar markets. Speaking to Energetica India, Jaydeep Gajera, CEO of Gronsol Inverter Technology LLP, said the plant has been developed through a strategic multi-crore investment focused on advanced production infrastructure and technology.

The Surat facility will manufacture a comprehensive portfolio of solar products, including on-grid inverters, hybrid inverters, micro-inverters, and Energy Storage System (ESS) solutions. According to Gajera, these offerings are designed to address applications ranging from residential rooftop systems to commercial installations, industrial units, EPC projects, and utility-scale solar deployments, ensuring Gronsol’s presence across the entire solar value chain.

Equipped with advanced manufacturing and quality-control technologies aligned with global standards, the plant features automated assembly lines, precision component integration, and extensive in-house testing capabilities. These include functional, thermal, load, and grid-simulation testing adapted to Indian grid conditions, along with burn-in and reliability tests to ensure long-term product performance. Strict incoming and outgoing quality inspection protocols further support consistent output quality.

Gronsol has also established in-house R&D and product validation facilities at the site, enabling faster development cycles, customised solutions for EPCs and utilities, and quicker incorporation of market feedback. These capabilities are expected to enhance product efficiency and durability while reducing reliance on external testing and development partners.

Highlighting the strategic importance of the location, Gajera noted that Surat’s position within a major industrial corridor provides strong supply-chain connectivity, access to skilled manpower, and efficient logistics, supporting pan-India distribution. The Phase-1 commissioning was completed during FY 2025–26 following detailed planning and infrastructure development.

The new manufacturing unit plays a central role in Gronsol’s long-term growth and indigenisation roadmap. By bringing production in-house, the company aims to achieve greater control over quality, costs, and delivery timelines, while accelerating innovation and product localisation. The facility is also expected to strengthen support for channel partners, distributors, and EPC players, while reducing import dependence and improving supply stability.

Gajera emphasised that the plant positions Gronsol as a serious domestic manufacturer, moving beyond the role of a system integrator or trader. With a rapidly expanding dealer and distributor network across India, the company is now better equipped to scale operations, support large-volume projects, and explore future export opportunities.

Looking ahead, Gronsol has already planned a Phase-2 expansion, which will further increase capacity based on market demand, export potential, and the introduction of new products, including advanced energy storage and hybrid solutions.

The commissioning of the Surat facility reinforces Gronsol’s commitment to the Make in India initiative and India’s growing renewable energy ecosystem. From its early beginnings with limited infrastructure to establishing a full-scale manufacturing operation, the company’s journey reflects its ambition to emerge as one of India’s fastest-growing and most trusted solar inverter brands.
