Xantrex RV3012 Inverter/Charger
The Xantrex RV3012 is a 3,000 watt inverter/charger that uses modified sine wave. It was introduced into the 42' Allegro Bus in the 2007 model year. Being a modified sine wave inverter/charger it's not best suited for that vehicle but because it's included, I've attached links to the manuals for it. More information is available on the Xantrex website.
The RV3012 communicates to the RC7 remote control panel. The RC7 is available as a model RC7/GS, with automatic generator start but chances are you'll have the Onan EC30 AGS unit instead. For more information on AGS modules please refer to the Generators category of this library. Following are a number of tech documents pertaining to this inverter/charger.
