Application scenarios

1.Dual-Input Commercial Rooftop Systems

Ideal for medium-sized commercial buildings requiring independent dual PV string inputs with separate output circuits. The dual MCB configuration allows independent control of two output lines.

2.Parallel Solar Installation Projects

Suitable for photovoltaic systems where two separate arrays need parallel operation while maintaining individual protection and control capabilities for each circuit.

3.Industrial Power Backup Systems

Perfect for industrial facilities requiring redundant DC power supply with dual input and dual output configuration, ensuring continuous operation through circuit redundancy.

4.Agricultural Solar Applications with Dual Loads

Designed for agricultural installations powering separate equipment systems, such as irrigation pumps and processing machinery, through independent protected outputs.

5.Hybrid Energy Storage Systems

Optimal for solar-plus-storage applications where dual outputs are required for connecting to both grid-tie inverters and battery storage systems simultaneously.
