Description
V-TAC OHS35K-100 – High-Voltage Modular LiFePO4 Energy Storage System 35.84 kWh
V-TAC OHS35K-100 is a high-voltage, modular energy storage system based on LiFePO4 cells, supplied as a complete kit ready for connection. The system operates at a rated voltage of 358.4 V and consists of seven stackable battery modules, a BMS control module, a base, and communication and power cabling. The stackable design allows the modules to be freely stacked one on top of another, making installation easy both indoors and outdoors. The integrated BMS with CAN communication monitors key operating parameters in real time — system voltage, current, cell voltage and temperature, and module temperature — while the intelligent SOC algorithm ensures optimal management of charging and discharging cycles. Remote online updates allow for maintenance and optimisation without the need for a service visit. The storage system is certified in accordance with the CEI 0-21 standard and covered by the manufacturer's 10-year warranty.
Advantages and applications
- Modular stackable design enabling flexible expansion and capacity adjustment to suit installation requirements
- Advanced BMS with real-time monitoring and remote online update capability — servicing and optimisation without a site visit
- Long-life LiFePO4 technology ensuring stable operation for many years of use
- High ingress protection rating allowing both indoor and outdoor installation — residential, commercial and industrial applications
- Complete kit with base, communication cable and power cable — ready for connection without additional accessories
