The most distinctive feature of this energy storage converter is its low voltage and high current. It can support a minimum voltage of 40V and has an output rated current of 100A. It is widely applied in many fields such as photovoltaic storage and charging, charging and storage, emergency disaster relief power supply and equipment aging, and is the first choice for industries that require bidirectional energy flow

Function Description:

  • More secure and reliable:

    Full high-frequency isolation design ensures the safety between the battery and the grid/load;
    Full digital control of DSP + CPLD, with multiple levels of software and hardware overcurrent, overvoltage, and over-temperature protection, ensuring safety and reliability;
    Dual DSP design, with stable and reliable performance;
    Reliable parallel connection function, facilitating power expansion, allowing up to 12 modules to be connected in parallel;

  • Higher efficiency:

    Compared to traditional bidirectional power supply solutions, it eliminates the line-frequency transformer, achieving higher high-frequency isolation efficiency, reaching over 95%;
    AC/DC adopts three-level technology, with a maximum efficiency of 98%;
    DC/DC adopts soft-switching resonant technology, with a maximum efficiency of 98%.

  • More intelligent and user-friendly:

    Equipped with an STS module, supporting seamless switching between grid-connected and off-grid modes;
    Covers multiple battery voltage levels for passenger vehicles (100V~750Vdc), with a wide battery voltage range;
    Wide grid voltage range and adaptive capability for 50/60Hz voltage frequency.

  • Lower cost:

    Compared to traditional bidirectional power supply solutions, high-frequency isolation eliminates the line-frequency isolation transformer, resulting in lower system cost;
    By using a single circuit to achieve both charging and inverting functions, with integrated charging and discharging, the cost is low;

  • More flexible configuration:

    Supports 19-inch standard rack installation, with a compact structure;
    Module hot-swappable design, allowing flexible system configuration;
    Facilitates system integrators to flexibly design different forms of energy storage or battery-to-grid systems.
