Freedom Won SOLVA AC261 261kWh Integrated-PCS BESS Cabinet
Freedom Won SOLVA AC261 261kWh Integrated-PCS BESS Cabinet
Description
Overview
The Freedom Won SOLVA AC261 is an integrated-PCS, AC-coupled Battery Energy Storage System (BESS) cabinet combining 261 kWh of LiFePO₄ storage, an on-board 125 kW power conversion system and intelligent system control in a single outdoor-rated enclosure. Its transformerless topology and all-in-one design make it a rapid-deploy platform for commercial and industrial energy storage.
Active liquid heating and cooling keep the battery packs and PCS at stable operating temperatures, while an integrated Cabinet Monitoring System (CMS), aerosol fire suppression and IP55 / C5 protection deliver safe, reliable operation in demanding environments. The AC261 scales to 20 cabinets in parallel on-grid (8 off-grid) for multi-MWh deployments.
Key Features
Integrated AC-Coupled Platform
