12-volt DC System
The majority of your motor home lighting is powered by 12-volt electricity. The 12-volt DC
system is composed of components that will operate when the following conditions are met:
Power is supplied by the chassis alternator when the chassis engine is running.
12-volt DC power is supplied when the shore power cord is plugged into a 120-
volt external power source. House batteries will be charged also in most situa-
tions.
The house batteries power many interior 12-volt components including the light-
ing fixtures, water pump, 12-volt motors, 12-volt appliances, etc., when the motor
home is not connected to a 120-volt power source.
Inverter/Charger fault conditions
Certain fault conditions will cause the inverter to shut down.
These conditions include:
High or low battery
Power consumption overload
Inverter overheating
Inverter internal fault
Refer to the inverter/charger owner’s manual for fault code
diagnosis and resolution.
Inverter/Charger 12-volt DC circuit breaker
Each inverter/charger and its 12-volt wiring are protected by a replaceable high current fuse
typically located on the frame rail near the auxiliary battery bank or in the battery box. A
2000 watt inverter/charger will be protected by a 300 amp fuse and a 3000 watt inverter/
charger will be protected by a 400 amp fuse.
Inverter/Charger integral 120-volt AC circuit breakers
The inverter/charger is equipped with integral 120-volt AC circuit breakers located on the
inverter/charger metal case. In overload conditions these circuit breakers will trip and inter-
rupt inverter/charger 120-volt AC input and/or output.
After correcting the overload condition, reset these circuit breakers to resume inverter/char-
ger 120-volt AC operation. Refer to the inverter/charger owner’s manual for additional
information.
For complete detailed operation and safety information refer to the manufacturer’s owners
guide found in your warranty packet. Follow all safety information displayed in the manual.
Inverter
NOTE:
High battery voltage may be caused by excessive or unregulated
voltage from solar panels and/or other external battery charging sources.
NOTE:
Leaving the inverter/charger in the “on” position when the motor
home is in prolonged storage (no 120-volt AC shore power connected) will
drain the auxiliary batteries even though all 120-volt AC appliances are
turned off.
