BigBattery ETHOS | 48V | 30.7KWH | Home Battery Backup LiFePO4

The BigBattery ETHOS 48V 30.7kWh energy storage system combines six stackable 5.12kWh LiFePO4 battery modules into a dual-tower, UL-certified configuration, delivering 30.72kWh of usable capacity and 600Ah for whole-home backup, off-grid living, or time-of-use load shifting at serious scale. Built on safe, stable lithium iron phosphate chemistry with an advanced integrated BMS, the ETHOS system provides maintenance-free operation with protection against overcharge, over-discharge, and thermal extremes — all housed in IP65 / NEMA 4X rated enclosures suited to garages, utility rooms, and other demanding installation environments. With 250A of continuous discharge and 12,800W of continuous power on tap, it powers an entire household's heavy loads while holding days of reserve capacity for extended outages.

Certified to UL1973, UL9540, UL9540A, and UN38.3, the ETHOS platform meets the safety standards required for permitted, grid-tied residential installations and is CEC listed for California solar projects. CANBus and RS485 communications ensure closed-loop compatibility with popular 48V hybrid and off-grid inverters, and the modular design leaves room to grow — additional 5.12kWh modules stack cleanly onto the same system whenever your energy needs increase. Backed by BigBattery's 12-year warranty, the ETHOS 48V 30.7kWh system is a straightforward, code-compliant foundation for lasting home energy independence.

ETHOS 48V Six Battery Module Features

  • 30.72kWh Whole-Home Energy Reserve: Six 5.12kWh LiFePO4 modules in a dual-tower configuration store enough energy to power a full household for days during extended outages or support true off-grid living with large solar arrays.
  • 250A Continuous Discharge Power: With 12,800W of continuous output, the system runs well pumps, HVAC equipment, kitchen appliances, and workshop loads simultaneously without strain.
  • UL-Certified Safety Platform: Certified to UL9540A, UL1973, and UN38.3, giving you the documentation needed for permitted, code-compliant residential energy storage installations.
  • Expandable Modular Design: Additional 5.12kWh ETHOS modules stack directly onto the same system, so your storage capacity can grow with your energy needs instead of requiring a full replacement.
  • Closed-Loop Inverter Communication: CANBus and RS485 protocols keep the battery and your 48V hybrid or off-grid inverter in constant communication for optimized charging and reliable performance.
  • Weather-Resistant IP65 / NEMA 4X Enclosure: Sealed against dust and water jets, allowing confident installation in garages, utility rooms, and other demanding environments.
  • Advanced BMS Protection: Built-in battery management guards against overcharge, over-discharge, and temperature extremes, delivering maintenance-free operation you don't have to think about.
  • Space-Efficient Dual-Tower Layout: Two side-by-side towers just 6.7 inches deep put over 30kWh of storage flat against a wall, leaving your floor space free for everything else.
