OutBack PSPV Combiner Box       


OutBack Power Systems now offers a PV array combiner which can be used with a wide variety of PV system designs and module configurations.   Can be configured with DC breakers for low voltage systems (under 125 VDC) or touch safe type fuse holders for high voltage systems (up to 600 VDC). The PSPV is designed to provide NEC code compliant overcurrent protection and interconnection of multiple PV panels or sub arrays into one or more PV arrays for connection to charge controllers or inverter systems. The PSPV is easily field configured to match your system design and ampacity requirements - It is shipped without the breakers or fuse holders installed – order the quantity, type and amperage needed below.
