Built with a high-capacity LiFePO4 (Lithium Iron Phosphate) battery bank, this system delivers safe, efficient, and long-lasting energy storage. Whether you’re enjoying a peaceful retreat or preparing for extended stays, this system ensures you have the power you need, whenever you need it.

System Specifications:

  • Battery Bank: 15kW LiFePO4 Battery Bank
    • State-of-the-art Lithium Iron Phosphate (LiFePO4) technology offers superior safety, longevity, and efficiency. With over 11,000 charge cycles, it delivers stable power and is more environmentally friendly than traditional batteries and can last 20+ years.
  • Inverter: 6kW Pure Sine Wave Inverter
    • Provides clean, consistent AC power, suitable for running sensitive electronics and all your household appliances.
    • Split Phase (120v/240v) so you can run a well pump if needed.
  • Solar Panels: 
    • This power unit does not come with solar panels, but you can add them to your order or use with your own solar panels. We recommend using at least 4,000 watts of solar panels with this system to optimize usage and charging.
    • AIB Off Grid carries Jinko Bifacial 580-watt solar panels as an optional add-on to this unit but any solar panels will work. If using these Jinko panels, we recommend pairing the unit with 10 panels total, or 2 strings of 5 for a total of 5800 watts.
  • Charge Controller: MPPT Charge Controller
    • Ensures optimal charging efficiency, protecting your battery bank and maximizing energy harvest from the solar panels.
