PV Array Combiner Box

The PSPV is a solar array combiner which can be used with a wide variety of system configurations and solar module types. The PSPV is designed to provide NEC code compliant series over current protection of the wiring of multiple PV modules or subarrays for connection to charge controllers, inverters or other systems components. The rainproof aluminum enclosure is easily field configured to match your PV system design and amperage requirements.
