    Smart Battery Storage – BESS by Bateria

    Your path to energy independence

    BESS is a modern battery storage system that allows companies to better manage electricity consumption, cut costs, and increase energy independence.

    With BESS you can:

    • Store self-generated electricity (e.g., from photovoltaics) and use it when it pays off the most
    • Optimize consumption peaks and reduce contracted power charges
    • Gain backup for grid outages
    • Earn revenue from energy markets (e.g., through spot trading or capacity services)

    Benefits of Bateria BESS

    📄

    PPDS Certificate

    In cooperation with Brno University of Technology and international labs, PPDS certification will be secured within 12 months.

    ⚖️

    Active Balancing

    BESS actively balances voltage between cells, increasing efficiency, reducing losses, and extending battery life.

    🔒

    Safe Operation

    Protections against short circuits, overvoltage, smoke, and gas minimize fire risk. Insulation monitoring helps detect issues early.

    📈

    Scalability

    Expandable capacity up to 2 MWh with direct connection to 3×400 V grid – no transformer required.

    🚛

    Easy Transport

    Weighing under 2.5 tons with compact dimensions, the BESS can be easily moved by forklift or crane.

    💻

    European Software

    Runs on a European-made control system from a Czech company, with no ties to Chinese networks. Ensures strong cybersecurity.

    🏝️

    Island Mode

    Allows fully off-grid operation and ensures reliable backup for critical infrastructure in case of outages.

    🌡️

    Temperature Control

    Cooling and heating keep the BESS within an optimal range, protecting it from overheating and freezing.
