Section 6: Electrical System
Inverter/Charger
Your motor home may have multiple 12-volt DC to 120-volt AC inverter/charger(s) installed
that are designed to temporarily run selected 120-volt appliances from house auxiliary bat-
tery power.
The inverter/charger(s) is located between the chassis frame rails in the cargo storage area,
the controls are operated from the touchscreen. 120-volt circuit breakers protecting inverter/
charger output circuits are located in the sub-panels(s) the front cabinet. Circuit breaker
labeling near the sub-panels indicate which appliances can be operated from inverter/charger
power. Refer to Power Cut Out Switch section for location of inverter disconnect switches.
Inverter/charger 120-volt AC output is a pure sine wave type. The inverter/charger will
operate most appliances, tools and other 120-volt AC equipment.
The inverter/charger also functions as a multi-stage 12-volt power converter/battery charger
when the motor home is connected to 120-volt shore power or when the generator is run-
ning. In this mode the inverter/charger charges the house auxiliary batteries. Chassis batter-
ies can also be charged either from shore power or using the generator.
NOTE: The inverter can be controlled through the Vega Touch system.
Refer to the touch screen user guide in your warranty packet or online at

The inverter/charger generates heat while operating and needs unrestricted
air flow for proper cooling. Do not store anything around or on top of the
inverter/charger that would restrict air flow around it.
Inverter/Charger Remote Controls
To enable automatic inverter operation during power blackout or brownout conditions leave
the inverter/charger(s) in "INVERTER" mode at all times. The inverter/charger is in "IN-
VERTER" mode when the green "INV" light on the remote control panel is illuminated.
When in "INVERTER" mode the inverter/charger(s) will be on standby when the motor
home is connected to 50 amp 120-volt AC shore power or when the generator is operating.
All connected appliances operate off of shore power or generator power during this time. If
shore power is interrupted and the generator isn't running, the inverter/charger(s) will auto-
matically activate providing 120-volt AC power to connected appliances. See the inverter/
charger owner's manual for additional information.
Inverter/Charger battery charging function
The inverter/charger functions as a multi-stage battery charger when the motor home is
connected to 120-volt AC shore power or when the generator is operating. The inverter/
charger automatically senses auxiliary battery condition and applies the appropriate battery
charging profile.
In the event the motor home auxiliary batteries become completely discharged, the inverter/
charger will be unable to sense battery voltage and will not begin its charge sequence. To
manually initiate charging, turn the chassis ignition key to the "on" position for a short pe-
riod of time. If the batteries do not charge, or fail to hold a charge, they may be defective.
See the inverter/charger owner's manual for additional battery charging information.
