The AC output of the generator powers the motorhome air conditioners, the AC
inverter/converter charger, all appliances and items plugged into the electrical outlets
of the motorhome. The number of electrical appliances that can be operated at any
given time depends upon how much power is available from the generator. If the
generator is "overloaded" or a short circuit causes "over current," the generator
will shut down or the circuit breaker will trip. If power consumption, in total,
exceeds the generator power output, compensation for temperature and elevation
may be necessary. Operate some appliances in sequence rather than all at the
same time.
NOTE: The generator may shut down when it is loaded nearly
to full power and an air conditioner (or other large motor load)
cycles on. For a brief moment during start up an electric motor
can draw up to three times the rated power. For this reason, it
may be necessary to operate some appliances in sequence when
air conditioners or other large motor loads are on.
It is important to remember that air density decreases as altitude increases,
causing the generator engine power to decrease. Power decreases at approximately
3% of the rated power each 1,000 feet (305M) of increase in elevation above sea
level. It may be necessary to operate fewer appliances at the same time when the
camping location is at a higher elevation. For example: 7500 watt generator at
5,000 ft. = 6375 watts net. Temperature also affects maximum output power. For
example: At 120º F. a 7500 watt generator produces 6000 watts net.
INFORMATION: The generator may shut down for other reasons
beside "overloads." Refer to the manufacturer's manual for
further information pertaining to causes for generator shut-
down.
When refueling there is always a possibility the fuel may be contaminated.
Contamination of fuel affects the performance of the generator. Diesel fuel may
contain water or a microbe growth (black slime). Propane, due to the refining
process, may contain lightweight oil. Any contamination of fuel greatly reduces the
total output of the generator and may cause erratic AC output.
NOTE: The motorhome manufacturer does not cover damage to
the generator caused by fuel contamination, or to appliances
due to erratic AC voltage.
