The ETHOS Control Box is the central hub that connects your inverter and ETHOS battery modules, regulating and monitoring system performance. The front LED interface provides at-a-glance visibility into system voltage, remaining capacity, BMS status codes, and inverter communication settings, so you can quickly assess health and operation. This unit is not a battery and must be paired with at least two stackable 48V 5.12kWh ETHOS battery modules to form a complete, working system.
Single 48V 5.12kWh ETHOS LiFePO₄ battery module engineered to expand an existing ETHOS stack or system—not a standalone kit. Integrates with the ETHOS controller and rack for UL-certified configurations, delivering safe, reliable, maintenance-free storage with advanced BMS protection. Modular by design, it adds capacity as needs grow and is backed by a 12-Year Warranty.
