A solar power combiner box is a device that combines the output of multiple strings of solar panels for connection to the inverter. This reduces the number of wires that need to go to the inverter. Multiple strings of solar panels are also combined together in parallel to produce higher output currents.
In an on-grid solar system, the PV combiner box is usually in need between the solar panels and inverter to decrease the connecting lines, facilitate maintenance, reduce losses, optimize system structure, and improve the safety and reliability of items. In the solar power system, this component plays an essential role.
To install a solar combiner box, first mount the solar charge controller on top of the solar battery bank. Then, connect the solar panel to the combiner box, and the combiner box to the solar charge controller. Finally, connect the solar battery bank to the solar charge controller and a working, direct current (DC) lamp with a switch.

Here’s the step-by-step process: The solar combiner takes the output of several solar PV cells and combines them into one line before they go on to the inverter. This process maintains the individual string voltages while adding up the currents, maximizing the power delivery to your inverter.
According to Northern Arizona Wind & Sun, it’s a must to use breakers in place of fuses for solar combiner boxes between 12 and 48 volts.
