Utility-scale AC recombiner

20 Jul 2015
Bentek Solar announces the newly designed AC Recombiner, engineered in partnership with Advanced Energy Industries to support utility-scale AE 1000NX inverters. The Bentek AC Recombiner is a free-standing unit that provides a means of combining the three-phase output circuits from one to three AE 1000NX inverters. It is installed in the circuit path between the inverters and the transformer supplied with the system. The output circuits from up to three inverters can be connected to the Bentek AC Recombiner. Each input on the Bentek AC Recombiner supports the connection of one inverter. In the case of a fault or failure with one or more of the inverters, the Bentek AC Recombiner allows continued operation of the rest of the connected units. Each inverter output circuit connected to the Bentek AC Recombiner has overcurrent protection in the form of parallel fuse pairs. The fuse ratings have been selected based on safety and National Electric Code (NEC) requirements. One major benefit of this solution is that it enables larger block sizes, up to 3 MW, allowing the customer to reduce AC collection system costs and optimize installation costs – such as reduced foundations and crane picks. This is enabled by the ±1000 VDC topology of the AE 1000NX inverter, allowing for larger block sizes without oversizing DC homerun conductor gauges versus comparable monopolar applications.
