Centralized Power Control for Your ETHOS System
BigBattery’s 48V ETHOS Control Box is the heart of the stackable ETHOS power systems, designed to provide seamless control and monitoring of your energy storage. This advanced control unit connects both to your inverter and ETHOS battery modules, regulating and monitoring the entire system for maximum performance. Whether you’re powering a residential home, cabin, or commercial office, the ETHOS Control Box ensures efficient and reliable energy management.
With its easy-to-read LED interface, you can instantly check system voltage, remaining battery capacity, BMS status codes (alerting you to the health of your batteries), and communication settings for your inverter. This ensures that you're always in the loop on your system's performance and health, allowing for quick adjustments or troubleshooting when necessary.
Note: The Control Box is not a standalone battery module and requires at least two stackable 5.12kWh ETHOS battery modules to function as part of a complete system.
