The ETHOS System was built to be a versatile off-grid 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. 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 our ETHOS with two cutting-edge 6000W split-phase inverter-chargers from EG4, which each feature their own LCD touch screen display, 2 MPPT inputs, an integrated UPS module for seamless on and off-grid switching, and the ability to handle PV arrays of up to 8000W. Plus, through their 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 through peak shaving and time-of-use offsetting.
Whether you’re looking to ensure emergency backup power is always available, or you’re looking to outfit your home with a uninterrupted power system to last all season, or all year long, the ETHOS ensures reliable, efficient power delivery day in and day out, allowing you to save on utilities, and most importantly, stay powered and prepared.
