One unit or a full site array.
The 4.5 MWh system is designed for parallel connection — multiple units can be deployed on the same site under a unified EMS, scaling total capacity without adding complexity. Whether your project needs 4.5 MWh or 20+ MWh, the same platform delivers.
Request Custom QuoteParallel Arrays
Connect multiple 4.5 MWh units in parallel — scale to 10, 20, 30+ MWh on a single site.
Built-in Safety
Integrated fire detection and suppression, climate control, and advanced BMS — critical for large-scale outdoor deployments.
Liquid Cooling
Liquid-cooled battery modules maintain optimal temperature for performance and cycle longevity.
Site Integration
Supports multiple grid topologies — optimised for direct renewable coupling or standalone grid-facing deployment.
All configurations are built on Prime's proprietary cell-to-system platform, manufactured entirely within Europe.
