The V-TAC VT-12040-1 battery is a 10.24kWh energy storage solution designed for residential and small commercial photovoltaic systems. It uses LiFePO4 technology, valued for its stability, long service life, and operational safety.
With a nominal voltage of 51.2V and a capacity of 200Ah, the battery is designed for low-voltage systems. It can store the energy generated during the day for use in the evening, at night, or during periods of reduced photovoltaic production.
The IP65-rated enclosure limits the ingress of dust and water, providing greater flexibility when choosing the installation location. Charging is permitted within a temperature range of 0°C to 60°C.
The declared service life is at least 6,000 cycles at 25°C and 90% depth of discharge. CAN communication enables data exchange with compatible inverters and management of the system’s operating parameters.

Compatibility and Integration
The battery communicates via CAN protocol and must be connected to a hybrid or off-grid inverter compatible with 51.2V low-voltage LiFePO4 batteries.
Compatibility depends on the inverter model, communication protocol, and firmware version. We recommend checking compatibility before purchase.
Installation, configuration, and commissioning must be carried out by qualified personnel in accordance with the manufacturer’s instructions and applicable regulations.
