1-200 Kw AC/DC On-Grid PV Combiner Box For PV System Single Phase Three Phase
An On-Grid PV Combiner Box also known as a grid-tied combiner box, is an essential component used in grid-connected photovoltaic (PV) systems. Its primary function is to consolidate and manage the output of multiple PV strings or arrays before connecting them to the grid.The PV on-grid combiner box serves as a central point where the DC output from multiple PV strings or arrays is combined and connected to the grid. It provides a convenient and organized solution for wiring and protection.
YTBWX on-grid PV combiner box features a series of protections, including anti-islanding protection, overvoltage protection, undervoltage trip, low grid voltage, input lightning protection, system overcurrent, and grid isolation. Accurate energy metering, transmission, and intelligent operation control are essential parts of a household grid-connected power generation system. The product has obtained industry-standard CCC certification, IS9001 quality management system certification, and others.
