Generator
Wattage
Capacity
Generator Running (Rated) Watts Generator Starting (Surge) Watts
Gasoline: 3800W Gasoline: 4750W
LPG: 3500W LPG: 4350W
What this means:
The generator can produce a maximum of
3800W/3500W on a continuous basis to sup-
ply ongoing power to your electronic devices.
NOTE: Also check the rated amperage for
each outlet and make sure not to overload
the individual outlets.
What this means:
Some devices such as box fans require short
bursts of extra power in addition to the rated
wattage listed by the device to start their
motors.
The generator can produce a maximum
wattage of 4750W/4350W for a short period
of time (seconds) to cover the extra starting
power required by your electronic devices.
Electronic
Device Wattage
Calculation
Find the wattage information of each device you plan to connect. The information should be
listed on the device or in its instruction manual, or you may refer to Fig. 11.
The wattage can be calculated using this equation:
Watts = Volts x Amperes
To calculate the total running watts of your
devices:
+ Add up the running wattages of all the
device(s) you plan to connect
= The total running wattage
This wattage should NOT exceed the running
wattage of 3800W/3500W.
It is recommended to maintain a load at or
below 3420W/3150W (90% of the rated
output) to ensure steady voltage output and
to prolong the generator’s lifespan.
To calculate the total starting watts of your
devices:
+ Add up the total running wattage of all the
device(s) you plan to connect
+ Add the single highest ADDITIONAL start-
ing wattage out of the device(s) you plan to
connect
= The total surge (starting) wattage
This wattage should NOT exceed the starting
wattage of 4750W/4350W.
If any of either of the total calculated running watts or starting watts is higher than the
capacity of your generator, adjust the load until both wattage requirements are met. Other-
wise you will overload the generator, and cause damage to the engine and your electrical
device(s).
CALCULATING THE WATTAGE OF YOUR DEVICE(S)
Connect electrical devices running on AC current according to their wattage requirements. Calculate the total run-
ning wattage and starting wattage of the device(s) you wish to connect, and MAKE SURE that they are within the
capacity of your generator and the capacity of each individual outlet.
