Solar PV Combiner Box 2 In 1 Out DC 600V/1000V box

Our 2-String PV DC Combiner Box is a professional solution for small-scale solar photovoltaic systems, designed to safely combine DC outputs from two solar panel strings while providing comprehensive protection. Featuring an IP65 waterproof and dustproof enclosure, it is ideal for residential split-roof PV, small commercial rooftop, and off-grid solar power systems.

Built with high-quality components including individual string fuses/DC breakers, dual surge protection devices (SPD), and a dedicated grounding terminal, this combiner box effectively safeguards your solar array from overcurrent, short circuits, and lightning strikes. The transparent cover allows easy visual inspection of internal components, while MC4-compatible connectors ensure quick and secure wiring.

Certified with CE, our 2-string PV combiner box supports 600V/1000V DC systems and is available in 2-in-1-out or 2-in-2-out configurations. It is the perfect choice for optimizing your solar power system's performance and reliability, protecting your investment for years to come.
