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.
When choosing a PV combiner box, consider the input DC voltage range and output power of the inverter. Based on these specifications, certain panels will be connected in series as a string, and certain strings will connect to the PV combiner box for junction. This connection is controlled by a circuit breaker and protected by an arrester before being fed to the inverter. Main feature: the PV combiner box allows for the connection of multiple strings of solar panels.
For instance, Beny’s product line can perform three tasks simultaneously in one configuration: a straight parallel, followed by a shootout to two different inverters. Alternately, that same box is capable of fusing up to four negatives and four positives for a transformerless job. Solar combiner boxes typically cost between $100 and $300.
For solar installations with two or three strings, a solar combiner box is not required. Instead, attaching the string to the inverter might be beneficial. The use of combiner boxes is ideal for large projects with more than 4000 strings.
The gain in energy efficiency you will notice from a solar combiner box will enable you to quickly recoup its cost. In comparison to merely plugging your solar panels into the inverter, you will be able to extract more power from them. Your reduced electric bill will quickly more than offset the expense of a solar combiner box.
The output of several solar strings is combined by the combiner box. Each string conductor lands on a fuse terminal as the output of the fused inputs is combined onto a single wire that connects the box to the inverter.
