EnergyCell 5 - 40.0kWh
OutBack EnergyCell 5: Your Power, Your Peace of Mind
The OutBack EnergyCell 5 isn't just a battery—it's the heart of a reliable, scalable, and safe power system for your home or small business. It represents a new standard in energy storage, combining a robust, modular design with a fully integrated, intelligent Battery Management System (BMS). It’s engineered to perform, built to last, and designed to give you uninterrupted power when you need it most.
Engineered with both homeowners and installers in mind, the EnergyCell 5 strikes a perfect balance between sophisticated technology and operational simplicity. Its design allows for seamless expansion as your energy needs evolve, while its robust construction and intuitive features make it a reliable and easy-to-manage addition to your home's power system.
NOTE: NEC Article 706.15 restricts the maximum capacity of individual battery systems
installed in a single unit to
20 kilowatt-hours (kWh) in certain jurisdictions, including the state of California. Check with your local AHJ.
