Custom PV Combiner Boxes for Rooftop, Ground-Mount, and Floating Solar Systems
Not all PV systems are created equal — and neither are their combiner boxes. Whether you’re installing on a roof, field, or water body, customization is key to optimal performance and safety.
Rooftop Solar Installations
Combiner boxes for rooftops are typically compact, lightweight, and often installed vertically to conserve space. They must be UV and weather-resistant due to direct exposure to the sun and rain.
Ground-Mounted Solar Systems
In ground-mount systems, combiner boxes can be larger and integrated with mounting structures. They’re usually designed for higher current capacity and include cable trays or connectors for long-distance runs to inverters.
Floating Solar Applications
For floating PV systems on reservoirs or lakes, the combiner boxes must be waterproof, corrosion-resistant, and mounted on floats or platforms. IP67 or higher ratings are recommended for water protection.
Optional Custom Features
- Integrated surge protection
- MC4 or cable gland entry
- String monitoring with wireless communication
- Color-coded wiring and clear labeling
Conclusion
Tailoring PV combiner boxes to specific site conditions ensures longer service life, improved safety, and better operational efficiency. Always consult with an experienced manufacturer for your installation environment.
