    Off Grid Energy Storage Key Features

    • Voltage (V): 25.6V signifies a lower voltage level, making this battery ideal for certain specific applications or smaller energy requirements.
    • Power Capacity (kW): At 3kW, it can supply a modest amount of power, suitable for supporting smaller households or specific applications within larger systems.
    • Energy Storage Capacity (Ah): With 120Ah, this battery has a good storage capacity, which indicates it can hold a substantial amount of energy for its size, providing power over a reasonable period before needing a recharge.
    • Advanced Energy Storage Wall-Mounted Design: Space-saving and convenient, the wall-mounted feature allows for easier installation and maintenance, fitting well into limited spaces.

    Off Grid Energy Storage Applications

    1. Supplemental Home Energy Storage: Perfect for smaller homes or as a supplementary system in larger ones, supporting specific critical circuits or appliances.
    2. Backup for Critical Loads: Provides power to essential devices during outages, such as medical equipment, lighting, or telecommunications devices.
    3. Off-Grid Power for Remote Applications: Ideal for remote cabins, shelters, or any location where a full-scale grid connection is impractical.
    4. Mobile or Portable Power Solutions: Can be a good choice for RVs, food trucks, mobile workshops, or any scenario requiring compact, reliable energy storage.


    • Installation and Integration: Professional installation is recommended to ensure safe and effective integration into your existing electrical system.
    • Load Assessment: It’s important to accurately assess your power and energy needs to ensure this battery’s capabilities align with your requirements.
    • Maintenance and Lifecycle: While generally low-maintenance, periodic checks are advised to ensure the system’s longevity and reliability.
    • Understanding Warranty and Support: Clarify the warranty terms, support options, and expected lifespan to gauge long-term viability and cost-effectiveness.
    • Local Regulations and Incentives: Check any local regulations regarding battery installation and potential incentives that might offset initial costs.
