The Freedom Won eTower 2 helps you take control of your energy costs by storing power when electricity is cheaper and using it when you need it most. Charge from solar or off-peak grid power, then power your home during expensive peak periods or keep essential loads running during outages.
Start with 5kWh of storage and expand in 5kWh increments up to 30kWh, giving you the flexibility to grow your system as your energy needs change.
With long-lasting LiFePO₄ battery technology, intelligent protection and smart monitoring, the eTower 2 is built for reliable performance and long-term energy savings.
