BigBattery ETHOS 15.36kWh 48V Battery System — K0950

Size storage around your essential loads

Use 15.36kWh of nominal DC capacity as part of an installer-designed backup or solar-storage system. Actual AC energy and runtime depend on usable depth of discharge, inverter efficiency, operating conditions and the loads you connect. A compatible inverter is required to power AC appliances.

What this package includes

Three 5.12kWh ETHOS battery modules, one ETHOS control box and one 4ft (1220mm) final-module-to-control-box power cable. The control box includes its base; module interconnects follow the manufacturer packing and installation documentation.

This is the battery-system package only. Inverter, solar panels, site wiring, grounding conductors, external protection and installation are separate unless expressly identified in the supplied packing list. Check the current manual for interconnections, placement and clearances before installation.

Communication and installation

ETHOS supports CANBus and RS485 communication. Confirm the specific inverter model, communication protocol and firmware before ordering. The manufacturer rates these configurations at up to 250A continuous DC discharge and 200A maximum charging; inverter and system limits may be lower. Installation, permits and any required system certification must be evaluated for the complete equipment combination.

Choosing your configuration

This listing is specifically for K0950: 3 modules and 15.36kWh. For expansion, use compatible ETHOS components and the manufacturer-approved wiring layout. Do not mix battery models or assume another kit includes the same cables.
