We request you to kindly take on record the above intimation Thanking you, Yours faithfully, For SWELECT ENERGY SYSTEMS LIMITED Arulkumar Pudur Shanmugasundaram CEO& Managing Director DIN: 08371976 Encl.: a/a PRESS RELEASE SWELECT Expands C&I Energy Solutions Portfolio with Rollout of SWEES EN+ Solar Hybrid Inverter Range - Built to grow with C&I businesses, from 5 kW to 50 kW and beyond. Chennai, September 26, 2026: SWELECT Energy Systems Limited is rolling out its scalable SWEES EN+ hybrid inverter range for Commercial & Industrial (C&I) customers. The range is available from 5 kW to 50 kW and can scale beyond 50 kW. It is designed around the load profiles, solar generation and energy storage needs of businesses. Customers can start with a system sized to their current needs and add capacity as operations grow. SWELECT Energy Systems Limited is strengthening its energy solutions portfolio with the rollout of its SWEES EN+ solar hybrid inverter range from 5 kW to 50 kW, designed to address the evolving requirements of Commercial & Industrial (C&I) customers. SWEES EN+ manages solar generation, battery storage and grid supply through a single system. The range is certified by the Bureau of Indian Standards (BIS) under the Compulsory Registration Scheme (CRS), which clears it for rollout on schedule in Q2 FY27. As energy costs rise and power reliability becomes a bigger concern, businesses want to make better use of the solar power they generate on-site and add storage for backup. SWELECT designs each system around the customer's actual load profile and application rather than offering a one-size-fits-all product. Commenting on the development, Dr. Arulkumar Shanmugasundaram, CEO & Managing Director, SWELECT Energy Systems Limited, said, “With the BIS certification for our hybrid inverters, we are now rolling out the SWEES EN+ range from 5 kW to 50 kW, with a strong focus on the evolving energy requirements of C&I customers. The range has been designed with scalability at its core, enabling solutions to be configured in line with varying load profiles, operational requirements and future energy needs.” The rollout of SWEES EN+ further strengthens SWELECT’s growing portfolio of energy solutions and builds on the company’s experience across solar manufacturing, EPC, power electronics and energy storage. Through continued investment in these areas, SWELECT aims to provide integrated and scalable energy solutions across a wide range of commercial and industrial applications.
