VALTRIX String 3.0
All-in-one containerised energy storage system · Valtrix String 3.0
3.13 MWh and 1.5 MW in a pre-assembled container. For large industry, solar farms and grid projects.
For businesses and industry, one of our technicians visits your premises to define the right capacity and power, taking your back-up needs into account. In coordination with your own in-house technicians, we choose the best position, indoor or outdoor, weighing installation costs and the distance to the main electrical board.
All-in-one containerised energy storage system
VALTRIX String 3.0 integrates 314 Ah LFP cells, the BMS, the power conversion system (PCS) and an in-house EMS in a pre-assembled, factory-tested container. At 217.5 kWh per m² it takes up over 26% less land, and it expands in blocks from 1.56 to 3.13 MWh.
Its one-converter-per-cluster architecture eliminates circulating current losses, and active balancing keeps the cells uniform. Lifetime discharged energy rises by more than 10%, and thermal management extends service life by more than 25%.
Safety is multi-level: dual-layer fire suppression from module to cabinet, predictive diagnostics with multiple sensors and explosion-proof design with active ventilation. With IP55 and C4 corrosion protection (C5 optional) it operates from −30 to 50 °C. Its AI cloud platform responds quickly and lets you take part in energy markets (VPP).
