Freedom Won SOLVA DC261 261kWh DC-Coupled Battery Cabinet
Freedom Won SOLVA DC261 261kWh DC-Coupled Battery Cabinet
Description
Overview
The Freedom Won SOLVA DC261 is a DC-coupled Battery Energy Storage System (BESS) cabinet delivering 261 kWh of LiFePO₄ storage through integrated DC busbars rated for 125 kW. Designed to pair with an external hybrid inverter, its flexible DC-coupled architecture lets you scale storage with your choice of inverter platform.
Up to 12 cabinets can be connected in DC parallel (with an additional controller), with external inverters connected in AC parallel. Active liquid heating and cooling, aerosol fire suppression, IP55 / C5 protection and a built-in Cabinet Monitoring System (CMS) deliver safe, reliable operation in commercial and industrial installations.
