Real Project Validation for Avepower Custom High-Voltage Battery Storage System
Avepower high-voltage ESS solutions are designed for real-world deployment, not just specification sheets. From compact cabinet systems to multi-cabinet parallel solutions, Avepower supports customers with scalable engineering and project-based battery configurations.
One of the best examples of our high-voltage ESS capability is a 522.496kWh commercial and industrial project in Lithuania. Developed together with a local installation partner, this system was engineered as a compact 832V DC solution for grid support and renewable energy integration. The final system used 4 × 42U cabinets, 2 clusters in parallel, and a continuous current of 200A, showing how Avepower can support not only battery supply, but also complete high-voltage system configuration and engineering coordination.
