Description
The 261kWh High Voltage LiFePO₄ Battery Kit with liquid cooling – OLITER IP65, V-TAC is an advanced energy storage solution designed for high-power commercial and industrial (C&I) applications, where high energy density, precise thermal control and reliability in continuous operation are essential.
The system offers a total capacity of 261 kWh, derived from 5 LiFePO₄ modules of 52.249 kWh each, with a module capacity of 314 Ah, and is optimised for industrial applications, production plants, logistics centres, large commercial buildings or integration into high-power photovoltaic systems.
LiFePO₄ technology & liquid cooling
The use of LiFePO₄ technology ensures :
The system is equipped with liquid cooling, an essential solution for high-capacity applications, enabling precise thermal control, consistent performance and cell protection under heavy load or high ambient temperatures.
High Voltage Electrical Performance
The High Voltage configuration enables efficient integration with industrial inverters and complex energy systems:
-
Total capacity: 261 kWh (equivalent to 260–300 kWh)
