Application scenarios

1.Large Commercial Rooftop Systems

Ideal for shopping malls, data centers and large commercial buildings requiring six PV string inputs with dual output circuits. The configuration supports high-capacity energy generation while maintaining individual string protection through 12 fuses.

2.Utility-Scale Solar Power Plants

Suitable for medium-scale solar farms where six PV arrays need consolidation into two main output circuits. The dual MCBs provide independent control for different inverter groups or grid connection points.

3.Industrial Manufacturing Facilities

Perfect for large industrial plants with significant energy demands. The 6-string capacity supports continuous operation of heavy machinery while the overload protection ensures equipment safety.

4.Agricultural Processing Complexes

Designed for large agricultural operations requiring power for multiple processing units, cold storage facilities and irrigation systems. The IP66 rating ensures reliable performance in farming environments.

5.Hybrid Energy Systems Integration

Optimal for large-scale solar-plus-storage projects where six PV strings supply power to both grid-tie inverters and battery storage systems through two independently controlled output circuits.
