ETL certified panel mount DC solar connectors

Wieland’s PST 40i1 DC solar connectors now include ETL certification for their panel mount (bulkhead) connectors and field assembled units. ETL certification assures users that Wieland PST 40i1 panel mount connectors have been tested by an independent testing laboratory and conform to applicable performance and safety standards. Rated to 40A DC, use the panel mount connectors for enclosure applications including DC-DC converters, combiner boxes, and transition boxes. External installation of panel mount connectors allows an enclosure device to be tested off-site and shipped ready to install in the field. The contact’s wire size ranges from 2.5mm² (14 AWG) through 10mm² (8 AWG), allowing for higher gauge wire to mitigate voltage drops. Connector resistance, typically below one milliohm, minimizes power losses. NEC code requires a tool to disconnect the PV connection. Wieland PST 40i1 connectors provide a low-cost solution using a safety clip, which can be removed with a standard screw driver.
