What is a Solar Combiner Box? A Solar Combiner Box is an essential electrical device used in photovoltaic (PV) power generation systems. Its primary function is to combine the output currents of multiple solar panel strings (PV strings) into a single output, which is then sent to the inverter for DC to AC conversion.
The combiner box’s role in a solar system is to aggregate the power output of multiple solar panels, simplifying wiring complexity, maximizing potential energy output, and significantly enhancing the efficiency and safety of photovoltaic equipment.
We offer a variety of solar combiner boxes, including DC and AC. DC combiner boxes cover 1-24 input channels, support 600V/1000V/1500V system voltage, and current range 10A-400A. AC combiner boxes support low-voltage and medium-voltage applications.
Given that solar installations are exposed to the outdoors, combiner boxes often include surge protection to protect the system from voltage spikes caused by lightning or other electrical disturbances. To prevent overcurrent conditions and protect wiring and components, combiner boxes are equipped with fuses or circuit breakers.
Our solar power systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
