BigBattery’s 48V ETHOS systems are here, and this 46.08kWh commercial configuration is the ideal solution for grid-tied power in your office building, warehouse, or job site, supported by comprehensive safety, reliability, and state-of-the-art features.

The ETHOS System was built to be a versatile commercial power solution, with a stackable, modular design for easy expandability, and all hardware included to wall-mount your ETHOS with an effortless installation. The ETHOS comes equipped with an IP65-rated casing, an internal fire suppression system, as well as an advanced BMS with auto cell-balancing to ensure long-lasting safety and reliability. Plus, its control box features an interactive LED display, along with CANBus and RS485 communication protocols, so you can always monitor the status and performance of your power.

But that’s not all. We pair this ETHOS system with 3 cutting-edge 12000W EG4 hybrid inverters, which feature their own LCD touch screen displays, 3 MPPT inputs each, integrated UPS modules for seamless on and off-grid switching, and the ability to handle PV arrays of up to 54000W. Plus, through their smart load control, AC coupling abilities, and peak shaving functions, you can meet your power needs and protect your business against unstable grids or rolling blackouts, while seeing huge savings each month on your electric bill.

Whether you’re looking to ensure emergency backup power is always available, or you’re looking to outfit your office building with a powerful solar system, the ETHOS ensures reliable, efficient power delivery day in and day out, allowing you to save on utilities, or get rewarded for giving back to the grid through net metering programs and other tax incentives.
