Its function is to aggregate the direct current (DC) from multiple PV strings and transmit it to the inverter. When designing a combiner box, it is crucial to fully consider the electrical parameters, especially voltage, current, and power, to ensure the system operates safely and reliably. [pdf]
There are mainly three types of solar inverters — string inverters, micro-inverters, and power optimizers. All these inverters have a different system. However, they have the same function, which is. [pdf]

The PV AC combiner box series are intended for use in photovoltaic (PV) systems designed with string inverters. The product combines various (2 to 6) string inverter out-puts into typically one output. The product contains over-current and overvoltage (optionally) protections at inverter level. [pdf]

In short, a solar combiner box is a centralized unit designed to collect, protect, and route solar-generated DC electricity efficiently and safely, acting as a bridge between solar panels and the inverter. DC Fuses and DC Circuit Breakers are essential components in a solar combiner box. [pdf]
A solar string refers to a series connection of solar panels. When optimally positioned within the solar PV system, the combiner box will help limit energy losses. Combiner boxes are required when there are more than three solar strings that need to be connected to the inverter. [pdf]
