Maximum Energy Production

Every component of the SG-CX P2 Series is engineered to maximize the amount of usable electricity generated by your photovoltaic system.

Advanced power conversion technology enables the inverter to operate with exceptional efficiency while minimizing conversion losses. Multiple independent MPPTs continuously optimize each group of PV strings, allowing the inverter to extract the highest possible energy output even when modules experience different orientations, tilt angles, or partial shading.

This intelligent design helps improve annual energy production while providing greater flexibility during system design.

Benefits include:

• Higher annual energy yield
• Increased return on investment
• Better performance during changing weather conditions
• Improved tolerance to partial shading
• Flexible array configurations
• Optimized production throughout the day

Advanced Multi-MPPT Technology

Modern commercial buildings rarely offer perfectly uniform roof layouts. HVAC equipment, skylights, varying roof elevations, and multiple orientations often require solar arrays to be divided into several sections.

The SG75CX-P2, SG110CX-P2, and SG125CX-P2 utilize multiple independent Maximum Power Point Trackers (MPPTs) that continuously optimize each connected PV string. This allows different sections of the solar array to operate independently while maximizing overall system performance.

By reducing mismatch losses and improving energy harvesting across complex installations, the SG-CX P2 Series provides greater design flexibility without sacrificing efficiency.

This makes the inverters particularly well suited for:

• Commercial rooftops
• Industrial facilities
• Warehouse buildings
• Educational campuses
• Municipal buildings
• Ground-mounted solar arrays
• Solar carports

Designed for Today’s High-Power Solar Modules

As photovoltaic module technology continues to evolve, commercial systems increasingly utilize larger, higher-output modules capable of producing greater current.

The SG-CX P2 Series has been designed to support modern high-power photovoltaic modules, enabling EPC contractors and installers to build larger, more efficient systems while reducing overall balance-of-system costs.

Support for flexible string configurations allows designers to optimize array layouts while maintaining excellent electrical performance.
