Residential ESS

X3-IES

  • 4K / 6K / 8K / 10K / 12K / 15K

The SolaX X3-IES is a high-performance three-phase residential ESS featuring 98.5% efficiency and 15kW continuous output. With multi-mode operation (on/off-grid) and modular battery expansion (10-60kWh), it offers exceptional flexibility. Advanced AFCI+DC arc protection and IP66 rating ensure maximum safety, while SolaX Cloud enables intelligent energy management for optimal self-consumption.
