Overview

REVOLUTIONIZING RESIDENTIAL ENERGY STORAGE! BigBattery’s 48V ETHOS systems are here with a powerful 20kWh outdoor configuration, the perfect solution for grid-tied power in your home, cabin, or large property. Featuring cutting-edge safety, reliability, and performance, the ETHOS system is designed to meet all your energy needs while delivering long-term value.

The ETHOS system features a stackable, modular design, allowing for easy future expansions. All the necessary hardware for mounting the system on an exterior wall, garage, or shed is included, ensuring a straightforward installation. The IP65-rated casing offers complete protection against the elements, while the internal fire suppression system and advanced BMS with auto cell-balancing ensure optimal safety and longevity.

The system's interactive control box includes an LED display and supports CANBus and RS485 communication protocols, allowing you to easily monitor the status and performance of your power.

To complete the setup, we pair the ETHOS with two 12000W Lux inverters—each featuring its own LCD touch screen, 3 MPPT inputs, and integrated UPS modules for seamless on/off-grid switching. These inverters can handle up to 36000W of PV array capacity, while their smart load control, AC coupling, and peak shaving capabilities ensure maximum efficiency and protection against unstable grid conditions, ultimately saving you money on your electricity bill.

Whether you're ensuring backup power for emergencies or outfitting your home with a high-performance solar system, the ETHOS system offers reliable, efficient power year-round.
