Battery Energy Storage Systems
OJAS Series: Modular & Containerized BESS (128 kWh to 5 MWh)
Energy storage engineered for Indian grid conditions
The OJAS Series represents Powertrace’s flagship line of Battery Energy Storage Systems. Every OJAS unit integrates our in-house PRANA High-Voltage BMS and VYOM Advanced EMS with Tier-1 LFP prismatic cells and a certified power conversion system.
With pre-wired outdoor enclosures, liquid cooling and built-in fire safety, OJAS minimizes site commissioning time from months to weeks.
One platform, four sizes.
From a 128 kWh all-in-one cabinet to a 5 MWh container. Scroll through the range.
