As energy costs continue to rise and solar adoption accelerates across Southeast Asia, high-voltage battery energy storage systems are becoming a critical component of reliable and efficient power infrastructure.
This case study highlights a 60kWh high-voltage battery energy storage project in Vietnam, where a stackable high-voltage LiFePO₄ battery system was successfully deployed and integrated with Solis and Deye (DEYE) hybrid inverters to support solar self-consumption, peak shaving, and backup power.
Vietnam's commercial and industrial (C&I) energy users face increasing pressure from:
Grid instability and peak-hour electricity tariffs
Mismatch between daytime solar generation and actual load demand
Growing expectations for system efficiency, safety, and long-term reliability
To address these challenges, the customer prioritized a high-voltage battery solution capable of delivering higher efficiency, reduced energy losses, and seamless compatibility with established inverter brands.
The project utilizes 60kWh high-voltage batteries for an energy storage solution, designed with a modular, stackable architecture for fast deployment and future scalability.
Key System Specifications
Total Capacity: 60kWh Battery
Battery Chemistry: Lithium Iron Phosphate (LiFePO₄)
System Voltage: High Voltage (HV Platform)
Design: Stackable, modular battery architecture
Inverter Compatibility: Solis & Deye high voltage hybrid inverters
Application Scenarios: Solar self-consumption, peak shaving, backup power
By operating at a higher voltage level, the system significantly reduces current flow, cable losses, and thermal stress, resulting in improved overall system efficiency and reliability.
From a technical and economic perspective, high-voltage battery energy storage systems offer clear advantages:
High-voltage batteries for energy storage operate at lower current levels, reducing power loss and improving round-trip efficiency.
High-voltage battery energy storage integrates seamlessly with Solis and Deye hybrid inverters, reducing commissioning time and system complexity.
The stackable architecture allows the high-voltage battery energy storage system to expand capacity as energy demand grows.
Advanced BMS and multi-layer protection ensure safe operation of high voltage batteries for energy storage in demanding environments.
The system was installed and commissioned on schedule, with a compact footprint and clean on-site layout. Since commissioning, the high-voltage battery energy storage system has demonstrated stable performance under Vietnam’s high-temperature and high-humidity operating conditions.
Key operational outcomes include:
Increased solar self-consumption rate
Reduced peak electricity demand from the grid
Reliable backup power during grid fluctuations
