This project showcases a robust solar-plus-storage system built around two Deye SUN-15K-SG05LP3-EU-SM2 three-phase low-voltage hybrid inverters paired with four Deye SE-F12 LiFePO₄ battery units. Designed for applications requiring reliable three-phase power, high energy independence, and scalable storage capacity, this configuration delivers 30kW of inverter capacity and 47.2kWh of usable battery storage—making it ideal for larger residential villas, farms, agricultural facilities, or small commercial and industrial (C&I) sites.

System Advantages & Benefits

Seamless Integration and Scalability
The Deye SUN-15K-SG05LP3-EU-SM2 inverters are fully compatible with the SE-F12 battery series, ensuring plug-and-play integration without compatibility issues. With support for parallel operation of both inverters and batteries, the system can be easily expanded to meet growing energy demands.

Energy Independence and Backup Security
The hybrid design combines solar, grid, and battery power into one intelligent system, allowing seamless switching between energy sources. The UPS-level switching (<10ms) ensures uninterrupted power for critical loads during grid outages.

Smart Energy Management
Deye Cloud provides real-time monitoring, dynamic scheduling, and precise load forecasting. Time-of-use functionality enables users to optimize battery charging and discharging based on electricity pricing, maximizing cost savings.

Long-Term Reliability
With 6,000+ cycles at 80% DoD, the SE-F12 batteries deliver over 16 years of reliable performance under daily cycling conditions. The 10-year inverter warranty further ensures long-term peace of mind.

Safety and Durability
LiFePO₄ chemistry provides superior thermal stability and inherent safety. The intelligent Battery Management System (BMS) with active fuse protection ensures complete battery protection. The IP65-rated inverters and wide operating temperature range (-20°C to 55°C) make this system suitable for diverse environmental conditions.

Application Scenarios
This 30kW / 47.2kWh configuration is ideally suited for:
Large residential villas with high electricity consumption;
Farms and agricultural facilities requiring three-phase power;
Small commercial and industrial sites;
Sites requiring blackout protection or energy storage backup;
Hybrid solar installations with three-phase loads.

Conclusion
The combination of two Deye SUN-15K-SG05LP3-EU-SM2 hybrid inverters and four SE-F12 batteries delivers a powerful, scalable, and intelligent energy storage solution. With 30kW of inverter capacity, 47.2kWh of battery storage, advanced energy management features, and industry-leading reliability, this system represents a turnkey solution for energy independence—whether for residential, agricultural, or small commercial applications.
