Description
V-TAC OHS30K-100 – High-Voltage Modular LiFePO4 Energy Storage System 30.72 kWh
V-TAC OHS30K-100 is a high-voltage, modular energy storage system based on 6 LiFePO4 modules with a total capacity of 30.72 kWh (usable capacity 24.58 kWh). The system operates at a rated voltage of 307.2 V and is supplied as a complete set: base, 6 x VT-OH-5K battery modules (each 5.12 kWh / 51.2 V / 100 Ah), a BMS control module with integrated CAN communication, and power and communication cabling. The stacked design allows for quick vertical assembly — the modules are stacked one on top of another on a stable base, with the whole system topped by a BMS control box with a display. The IP65 protection class allows installation both indoors and outdoors, providing great flexibility when designing residential, commercial and industrial installations. The integrated BMS monitors system voltage, current, cell voltage and temperature, and module temperature in real time, while an intelligent SOC algorithm ensures precise control of the state of charge. The system also supports remote software updates, making maintenance and optimisation of the storage system's operation easier without the need for a service visit.
Applications and advantages
- Residential and commercial energy storage systems with photovoltaic installations — buffering surplus PV production
- Backup power systems for facilities requiring continuity of power supply
- Optimisation of energy consumption in commercial and industrial buildings — reduction of peak grid demand
- Modular design allows capacity to be tailored to the investor's needs — from smaller configurations to extensive systems
- Lifespan of ≥ 6,000 cycles (0.5C/0.5C at 25°C, EOL 70%) and manufacturer's 10-year warranty
