Xantrex Inline Transfer Relay f/PROwatt SW

The Xantrex Inline Transfer Relay for PROwatt SW is a 15-amp marine power management component designed to automatically switch AC power between shorepower and inverter sources. This relay simplifies dual-source power switching on vessels equipped with Xantrex PROwatt SW inverters, eliminating the need for manual intervention when transitioning between shore connections and onboard power generation. The easy-to-mount design makes integration into existing marine electrical systems straightforward for both new installations and retrofits.

The relay features a power plug connection to the inverter's GFCI outlet and hardwire cordage for AC input and output interfacing, providing flexible installation options depending on your vessel's electrical architecture. The 15-amp rating handles typical single-phase AC loads common in mid-sized recreational and fishing boats. By automating source selection, the relay reduces operator workload during port approaches and departures—critical during weather transitions or when managing power priorities at anchor. The component's compact footprint and straightforward mounting requirements mean minimal modification to existing cabinetry or electrical enclosures.

This relay is engineered as an accessory specifically for the Xantrex PROwatt SW inverter product line. Owners operating PROwatt SW systems who depend on both shore and inverter AC power—whether during liveaboard cruising, extended offshore fishing trips, or anchorage stays—benefit from automatic switching that protects against accidental dual-source conflicts and simplifies power management routines. It is particularly valuable on boats where power redundancy is essential, or where frequent transitions between dockside and cruising power modes occur regularly.
