Combiner boxes are required when there are more than three solar strings that need to be connected to the inverter. When working with less than three solar strings, they can be connected directly to the inverter without additional devices. For small residential solar systems with one or two strings, a solar combiner box is not a strict requirement.

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.
Solar combiner box manufacturers often make boxes that can accommodate 3 strings or more. In order to size the box correctly, determine the number of strings in your system, and use that to find the minimum box size. The box is also sized based on the string voltage and current levels.
