Xantrex PROwatt SW 15A Inline Transfer Relay

The Xantrex PROwatt SW inline transfer relay provides a straightforward way to select between shore power and inverter-supplied AC on a compatible installation. Rated for 15 amps, it is intended for circuits that need to use an available 120V AC source without manually moving a plug between power supplies. The relay is an accessory for specified PROwatt SW inverter models, rather than a general-purpose whole-boat transfer switch.

An attached power plug connects to the inverter GFCI receptacle, while hardwire leads provide the other AC input and output connections. This arrangement can simplify integrating a compatible inverter with an existing AC-fed circuit. Xantrex lists a nominal transfer time of 80 milliseconds and 120V, 60Hz operation. The compact relay housing is made for mounting in a suitable electrical location.

• Switches between shore-power and inverter AC sources
• Plug connection for compatible inverter GFCI outlet
• Hardwire leads for AC input and output
• 80 ms nominal transfer time

Match the relay to the inverter model and the circuit current before planning the installation. Shore-power and inverter wiring need to be connected according to the supplied electrical instructions and applicable safety requirements. For a correctly specified circuit, the transfer relay provides a dedicated switching component without replacing the rest of the AC distribution system. Browse more power inverters at CritPro.
