What Acelion Energy does
Acelion Energy Storage Solutions Private Limited is an India-based designer and manufacturer of lithium iron phosphate (LiFePO4) battery energy storage systems and hybrid inverters, headquartered in Salem, Tamil Nadu with a regional office in Chennai. The company's stated engineering heritage spans 39 years, although the current legal entity appears to have been formalized more recently. It markets a vertically integrated portfolio across four segments — residential (Neo SL and UL battery series, NEUSYNC SL and UL inverters), commercial (Neo RH batteries, NEUSYNC UH inverters), industrial (Orion-260K and Orion-UTL-418 liquid-cooled systems), and utility (Axion / Axiom 5M 5 MWh liquid-cooled DC outdoor BESS) — serving customers in India and, on a project basis, in Australia.
The technical stack centers on LiFePO4 cell chemistry with cycle lives of 6,000-10,000 cycles, liquid-cooled thermal management for industrial and utility products, and a multi-tier safety architecture for residential systems. The flagship Axiom 5M is a 5 MWh outdoor liquid-cooled DC system targeted at grid stability, peak shaving, and renewable integration. Manufacturing is conducted in-house at the Salem facility, and the company operates an active Operations and Maintenance services business managing 400 MW of installed renewable capacity, separate from hardware sales.
The revenue model combines hardware sales of storage systems and inverters with recurring O&M services tied to deployed assets. Go-to-market is direct enterprise field sales with regional coverage through the Chennai office, supported by a website-driven lead capture process. Only one customer is disclosed by name — Goorambat East Solar Farm in Australia, using the Luminous S4 fleet. Pricing is not publicly disclosed. No external institutional funding, parent company, named leadership, certifications, or patents are reported in the available sources, representing material disclosure gaps for a private company at this stage.
