Description

Overview

The Freedom Won SOLVA AC418 is a large-scale, integrated-PCS Battery Energy Storage System (BESS) cabinet combining 418 kWh of LiFePO₄ storage with an on-board 215 kW, 690 V power conversion system. Its higher-voltage AC architecture is built for MW-class commercial, industrial and utility deployments, pairing with an MV step-up transformer for grid-scale sites.

Active liquid heating and cooling (8 kW cooling), aerosol fire suppression, IP54 / C5 protection and a built-in Cabinet Monitoring System (CMS) deliver safe, reliable operation. The AC418 scales to 20 cabinets in parallel on-grid (8 off-grid) for multi-MWh energy storage.


Key Features

Grid-Scale Integrated Platform

  • 418 kWh LiFePO₄ storage with 90% depth of discharge
  • On-board 215 kW PCS with 690 V three-phase (3P+N+PE) AC output
  • Use with an MV step-up transformer for grid-scale deployment

Advanced Thermal Management

  • Integrated liquid heating (2 kW) and cooling (8 kW) for stable pack temperatures
  • Intelligent air cooling for the inverter/PCS section

Grid Support & Scalability
