The I-G3N  I-G3N IG3N e-Wall eWall Lithium LiFePO4 Solar battery 48V Li-ion Ironi-Wall Lithium LiFePO4 Battery is a wall-mounted high-quality Lithium Iron Phosphate (LiFePO4) battery that comes standard with built-in intelligence and stable discharge performance. It provides more than 4,000 cycles at 80% DOD (at 25°C).


The I-G3N i-Wall is scalable in multiples of 5.4 kWh, and can be increased in size at a later stage with the i-Expansion unit, ideal when the initial investment in a bigger battery is a little too high in the beginning.
