BigBattery ETHOS 10.24kWh 48V Battery System — K0948

Choose the right ETHOS package

Use this package with a compatible 48V-class inverter in an installer-designed backup or solar-storage system. The included control box manages the battery stack; confirm the inverter model, firmware and communication setup before ordering.

Included with K0948

Two 5.12kWh ETHOS battery modules, one ETHOS control box with its base and included inverter power/communication cables, and one 31.5in (800mm) final-module-to-control-box power cable pair. Each battery-module box includes a 0.7ft red/black parallel cable pair, a 0.7ft communication cable, two L wall-mounting brackets and fasteners. The current manual also shows the module side covers.

Solar panels, site wiring, grounding conductors, external protection and installation are separate. Only the equipment described above is included. Follow the manufacturer packing list and installation instructions for the supplied components.

Plan capacity and compatibility

The 2 included modules provide 10.24kWh of nominal DC energy at 51.2V. Actual AC runtime depends on the complete system, usable battery capacity, inverter efficiency and connected loads. Installation and any required system certification must be evaluated for the complete equipment combination.

ETHOS systems use CANBus and RS485 communication. Expansion does not automatically increase inverter output. Confirm battery matching, firmware, control-box limits and protection before adding modules.
