AXIstorage Li SV1 Energypack 3.37kWh – Expansion Module for LFP Battery Storage
The AXIstorage Li SV1 Energypack is a Lithium Iron Phosphate (LFP) battery module offering 3.37kWh of usable capacity, designed to expand AXITEC’s modular AXIstorage Li SV1 storage system. Following a building-block principle, multiple Energypacks can be combined into a complete system ranging from 10.1 to 23.6kWh of usable energy – matching the actual energy demand of a home or commercial property.
With a nominal voltage of 48V, a maximum charge/discharge current of 37A each, and an efficiency of up to 96%, the module is built for high efficiency in continuous operation. Passive cooling and a robust IP55 enclosure allow reliable operation across a temperature range of 0–50°C.
Combined with the AXIstorage Li SV1 base unit, the system is compatible with over 100 inverters from leading manufacturers and is suitable for residential, commercial, and e-mobility applications.
