8x Modules + 12kW (18kPV) Inverter

BigBattery’s 48V ETHOS systems are here, and this 40.9kWh configuration is the ideal solution for grid-tied power in your family home, cabin, or mansion, supported by comprehensive safety, reliability, and state-of-the-art features.

The ETHOS System was built to be a versatile home power solution, with a stackable, modular design for easy expandability, and all hardware included to mount your ETHOS to your wall 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.

But that’s not all. We pair our ETHOS with a cutting-edge 12000W EG4 hybrid inverter, which features its own LCD touch screen display, 3 MPPT inputs, an integrated UPS module for seamless on and off-grid switching, and the ability to handle PV arrays of up to 18000W. Plus, through its smart load control, AC coupling abilities, and peak shaving function, you can meet your power needs and protect your home 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 home 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.
