Xantrex Automatic Generator Start SW2012 SW3012 Requires SCP

The Xantrex Automatic Generator Start (AGS) for SW2012 and SW3012 inverter/charger systems is a Xanbus-enabled power management controller that automates generator activation when battery voltage drops or loads exceed inverter capacity. Unlike manual monitoring, the AGS intelligently engages a compatible generator to recharge depleted batteries or support heavy electrical demands without user intervention, delivering critical power intelligence to marine electrical systems.

Designed specifically for Xantrex MS and RS series inverter/charger platforms, the AGS eliminates constant battery voltage surveillance and manual start procedures. The device communicates directly with compatible generators via Xanbus protocol, enabling programmable thresholds for automatic startup and shutdown. This targeted approach reduces engine runtime and fuel consumption by activating power only when system conditions warrant it, while minimizing wear on auxiliary engines from unnecessary cycling.

The Xantrex AGS is engineered for cruising sailboats, trawlers, offshore fishing vessels, and expedition-equipped yachts where reliable battery management and autonomous power response are essential. Crews operating extended offshore passages, overnight fishing trips, or remote anchorages benefit from hands-free generator control, freeing attention for navigation, vessel monitoring, and safety systems. The compact 8 x 2 x 11-inch form factor allows integration into existing Xantrex power systems without major panel reconfiguration.

Installation requires the optional SCP (System Control Panel) for menu-driven configuration of voltage thresholds, generator type, and auxiliary load settings. The modular architecture ensures compatibility with Xantrex ecosystems already in service aboard marine vessels and RVs. Weighing 1.9 pounds with standard DIN-rail mounting, the unit integrates into existing Xanbus networks without significant footprint demands.
