Problem
India’s rapid expansion of solar and renewable generation, along with growing commercial and residential electricity demand, creates a need for reliable, long‑life energy storage that can smooth intermittency, reduce peak‑hour costs, and replace diesel generators. Existing storage options often involve bulky installations, high auxiliary consumption, and limited compatibility with local inverter ecosystems.
Solution
Cygni provides modular lithium‑iron‑phosphate (LFP) battery systems designed for large‑scale BESS, commercial‑industrial, and residential applications. Their products use liquid‑cooled containers or compact stackable modules that can be deployed quickly in rugged Indian conditions and integrated with a wide range of Tier‑1 power conversion systems. Certified to UL1973, UL9540, IEC 61850 and other safety standards, the batteries deliver high round‑trip efficiency, low auxiliary power draw, and a calendar life of up to 25 years, matching the lifespan of solar plants. The company offers plug‑and‑play designs, cloud‑based monitoring, and optional hybrid inverter compatibility, enabling customers to implement peak‑shaving, load‑shifting, and backup power without extensive engineering effort.
Target Audience
Primary customers are utilities, solar farm developers, and commercial‑industrial facilities seeking large‑scale battery energy storage, as well as homeowners and residential solar installers requiring compact, safe LFP storage solutions.
