Product Description

Product Description

A string combiner box with MC4 connectors is a device used in photovoltaic (PV) systems to combine the output of multiple solar panels into a single DC output. The box typically includes several input terminals, each with an MC4 connector, where the positive and negative wires from individual solar panels can be connected. The box then combines these inputs into a single DC output, which is typically connected to a charge controller or inverter.

The number of input terminals on a string combiner box can vary, but a common configuration is four inputs. This means that the box can combine the output of up to four solar panels into a single DC output. The MC4 connectors are a common type of connector used in PV systems, and are designed to be weather-resistant and easy to install.

Overall, a string combiner box with MC4 connectors is an important component in many PV systems, helping to ensure that the output from multiple solar panels is combined efficiently and safely.
