Product Description
The Deye 30–50kW Hybrid PV + ESS System combines the powerful Deye SUN-30/35/40/50K-SG01HP3-EU series hybrid inverter with the BOS-G PRO high-voltage LiFePO₄ battery solution, delivering a reliable and efficient solar + storage system for commercial and industrial applications.
The Deye inverter provides up to 50kW of three-phase output with 100A charge/discharge capability and flexible battery voltage support (160–800V). It allows on-grid, off-grid, and generator operation with seamless switching and AC coupling for retrofit installations.
The BOS-G PRO LFP battery uses LiFePO₄ cells with modular scalability, ranging from 25.6kWh to 87.04kWh per rack. Intelligent BMS communication via CAN/RS485 ensures full system protection, long cycle life (>6000 cycles), and 90% depth of discharge.
This combination system is ideal for self-consumption optimization, peak shaving, and reliable backup power, making it a preferred choice for factories, schools, commercial complexes, and small industrial sites.
