The generator can be selected for use when AC shore power is not avail-
able. The generator’s maximum amount of output power, measured in watts, is
calculated at an elevation of 500 feet above sea level. This figure will decrease
slightly with a higher altitude. Ambient temperature also affects total maximum
output. The amount of AC electrical load applied to the generator determines
fuel consumption.
The optional inverter/charger can be used for silent AC power if shore
power is not available, and using the generator is not going to be selected as a
secondary power source. This device has limited AC power output, measured
in watts. It operates only selected appliances and outlets. The optional invert-
er/charger is two components in one. First is as an auxiliary 120 Volt AC
power source that uses 12 Volt DC house battery power to invert to 120 Volts
AC. The second function of the inverter/charger is to use 120 Volts AC power,
supplied from either shore power or the generator, and convert it to 12 Volts
DC power to recharge the batteries. When dry camping, the inverter may be
used to supply power to selected outlets.
The main battery disconnects are located in the curbside battery compart-
ment. In the compartment are a pair of battery disconnects: One for the chassis
batteries and the other for the house batteries. Turn off the batteries any time
the motorhome is going to be stored and not in use. If possible, leave the
motorhome plugged into an AC source with the battery disconnects on. This
will help prevent the batteries from going dead. There are small "parasitic"
loads that are present on both the house and chassis batteries. Some are federal
mandate items, such as the LP detector. If the motorhome will not be used, or
will be stored for more than 48 hours, it is recommended to turn the batteries
off.
