Discover Volthium\u2019s 51.2 V 314 Ah lithium battery<\/strong>, an energy storage solution designed to optimize residential hybrid solar systems<\/a>. With a nominal capacity of 314 Ah<\/strong> and available energy of 16.1 kWh<\/strong>, it can store a significant amount of energy to power a residence, support essential loads during an outage, or maximize the use of energy produced by solar panels.<\/p>\n

Operating at low voltage, it simplifies integration into the system while offering a safe, efficient solution adapted to modern residential energy needs.<\/p>\n

 <\/p>\n

A solution designed for hybrid residential solar systems<\/h4>\n

The 51.2 V 314 Ah battery can operate in different configurations:<\/p>\n

    \n
  • grid-connected system;<\/li>\n
  • backup power supply;<\/li>\n
  • off-grid installation;<\/li>\n
  • hybrid solar system with a compatible inverter.<\/li>\n<\/ul>\n

    It stores the energy produced by the solar panels to make it available when it is truly needed, particularly in the evening, during peak periods, or in the event of a power grid outage.<\/p>\n

    Powerful and scalable capacity<\/h4>\n

    Its modular architecture makes it easy to increase the system\u2019s total capacity as energy needs evolve.<\/p>\n

    Up to 32 units can be connected in parallel<\/strong>. The battery can also be combined with a 51.2 V 100 Ah 3U rackmount battery<\/strong>, allowing capacity to be added gradually without having to replace the existing installation.<\/p>\n

    This modularity makes it a solution suited both to current residential projects and to installations designed to evolve over time.<\/p>\n

    <\/h4>\n

    Simple and well-integrated installation<\/h4>\n

    The battery is equipped with Plug & Play<\/strong> quick connectors, making it easier to connect and reducing installation complexity.<\/p>\n

    Its junction box can accommodate a Victron Lynx Power In<\/strong>, allowing for cleaner integration with certain Victron configurations. Its adjustable feet also make it easier to position on the floor. The installation must, however, be carried out by qualified personnel, in accordance with electrical standards and local requirements. Humans like to connect 16 kWh devices as if they were desk lamps, but in this case, improvisation is best avoided.<\/p>\n

    <\/h4>\n

    Intelligent management and remote monitoring<\/h4>\n

    Its integrated BMS ensures cell management, protection, and active balancing.<\/p>\n

    It protects the battery against:<\/p>\n

      \n
    • overcharging and excessive discharging;<\/li>\n
    • overcurrent;<\/li>\n
    • short circuits;<\/li>\n
    • temperatures that are too high or too low.<\/li>\n<\/ul>\n

      CAN and RS485<\/strong> communications allow data exchange with several compatible inverter models, as well as system operation monitoring. The battery notably supports brands such as Victron, Sol-Ark, Schneider, LuxPower, Deye, SMA, Growatt, and Solis.<\/p>\n

      Designed for real-world conditions<\/h4>\n

      The battery has an IP65<\/strong> protection rating, providing resistance to dust and water jets.<\/p>\n

      It also features an integrated heating system that supports operation when temperatures are low. Its operating range extends to approximately \u221220\u00b0C to 50\u00b0C<\/strong>, depending on charging and discharging conditions.<\/p>\n

      Its quiet operation and lack of regular maintenance make it a particularly suitable solution for residential installations.<\/p>\n

      Safety and durability<\/h4>\n

      The battery uses LiFePO4<\/strong> chemistry, recognized for its stability and long service life.<\/p>\n

      It is certified according to several important standards, including:<\/p>\n

        \n
      • UL1973 ;<\/li>\n
      • UL9540A ;<\/li>\n
      • UL9540 DC-ESS.<\/li>\n<\/ul>\n

        It offers a service life of 8,000 cycles or more,<\/strong> depending on operating conditions, as well as a 10-year<\/strong> limited warranty.<\/p>\n

        Main features<\/h4>\n
          \n
        • Nominal voltage: 51,2 V<\/strong><\/li>\n
        • Nominal capacity: 314 Ah<\/strong><\/li>\n
