Introduction of the grid connected ac PV array combiner box
AC PV combiner box in grid tie system is used to bring together the output of multiple PV inverters and then connect to the grid. It could lessen the cable for the connecting between inverters and the grid. To a large extent it reduces distribution material cost and workload.
Features of the grid connected ac PV array combiner box
* Protection class IP65 for outdoor use
* Simply wiring, easy operation, reducing the wiring workload
* High efficiency and strong security with standard configuration of AC lightning protection modules
* Wall mounting with small volume and light weight, reducing installation time.
