BigBattery ETHOS 61.4kWh + 3x EG4 18kPV Hybrid Inverter (ESS) | Grid-Tied Home Solar System
High-Capacity 61.4kWh LiFePO₄ Energy Storage with EG4 18kPV Hybrid Inverters for Commercial Applications
Power your business with confidence using the BigBattery 48V 61.4kWh ETHOS Energy Storage System, paired with three EG4 18kPV Hybrid Inverters. Ideal for office buildings, warehouses, job sites, and commercial facilities requiring reliable, high-capacity power.
With 12 stackable 5.12kWh ETHOS battery modules, the system provides over 60kWh of premium LiFePO₄ storage. Each module features Tier 1 lithium cells, IP65-rated enclosures, fire suppression, advanced BMS, and self-balancing for optimal performance.
Each ETHOS Control Box supports CANBus and RS485 communications and includes an LED display for real-time monitoring of system health, voltage, and energy levels.
The kit includes three high-output 12kW EG4 18kPV Hybrid Inverters, featuring 3 MPPTs, integrated UPS functionality, smart load control, and support for up to 54kW of solar input. Grid-tied or off-grid, the inverters provide smooth transitions, peak shaving, and AC coupling for efficient energy management.
