314Ah 16kWh WallMount AllWeather Battery + 18 KPV/12kW AC | Split-Phase | 4-MPPT | Remote Wi-Fi Monitoring | ESS System

The EG4 314Ah All-Weather Battery + EG4 18kPV ESS System is a high-capacity, rugged energy solution designed for both on-grid and off-grid applications. Combining the 16kWh EG4 WallMount All-Weather LiFePO₄ battery with the powerful EG4 18kPV hybrid inverter, this system delivers reliable, scalable energy for residential, commercial, and backup power needs. The EG4 18kPV provides up to 12,000W split-phase output at 240V with 18,000W of maximum utilized solar power, a recommended maximum solar input of 21,000W, and three MPPTs. This enables strong solar production and seamless power management between solar, battery, generator, and the utility grid. Paired with the 314Ah All-Weather battery—featuring 200A continuous output, 8,000+ cycle life, and a next-generation smart BMS with active cell balancing—this system ensures stable, efficient energy delivery over the long term. Built for outdoor installations, the battery features a durable IP67-rated enclosure, integrated self-heating for cold climates, and Bluetooth + Wi-Fi connectivity for real-time monitoring and OTA updates. The outdoor-rated EG4 18kPV adds a 200A AC bypass, closed-loop battery communication, and support for up to 10 inverters in parallel, delivering advanced performance with flexible scalability.
