DC/AC Hybrid Combiner Box

A combiner box is used in solar power systems to combine the output of multiple solar panel strings into a single DC output. It helps organize wiring, simplifies installation, and provides protection through fuses, circuit breakers, and surge protection devices. Commonly used in large-scale and rooftop solar installations, it improves system safety, reliability, and maintenance efficiency.
