Performance inverters designed for RVs and boats Designed for RV and marine electrical systems that already have a battery charger or generator installed, Xantrex PRO Inverters deliver modified sine wave power for small appliances, TVs, and other onboard electronics from a battery bank. The XM 1000 and 1800 models are the perfect complement to generators when shore power is unavailable, to quietly and efficiently provide household power when needed. The Xantrex PRO Series design is both user friendly and versatile. These inverters feature a detachable, digital remote control to display precise inverter, AC source and battery status information from one convenient location. A built - in transfer switch automatically detects when generator or shore power status changes to ensure power is always available. Both XM 1000 and 1800 models are designed for demanding RV and marine conditions. They meet FCC Class B regulations to eliminate interference potential with other electronics, while UL 458 certification means they meet strict RV and marine safety standards. Versatile enough to be mounted either horizontally or vertically, these inverters can be easily installed to fit into any compartment. Conformal coated boards also minimize the chance of problems from moist operating conditions. Full featured MSW with built - in transfer switch. Plug electronics directly on the unit or hardwire.
