Lets say I have a Yamaha EF1000 that can put out 9a max. (Which I don't)
And lets say my refrigerator draws 13a to start, and 1.5a to run. (Which it
What will happen if I try to start the fridge off the genny?
I am guessing the generator will simply stall, with no harm to either. Is
Now for the really foolish question... Any way to start the fridge off the
Well, it won't stall. But it will trip the breaker if you try to exceed
the designed rating.
The EF1000 is rated at 6.67 amps(800VA) continuous, 8.3 amps(1000VA) surge.
It's just not going to start your fridge w/o assistance, like a sizeable
inverter & a battery bank charged from the generator.
It may stall. We tried (just for giggles) to run a hobart MIG welder off my
troy bilt 2500 watt generator. With the welder turned up to about 3/4 of
capacity, pulled the trigger, and it killed the troy bilt engine.
stall or trip breaker, in a very marginal operation it might harm the
fridge by continious running undervolt.
wh not get a bigger generator or apartment sized fridge or inverther
and run fridge off your vehicles battery with car running.
Indeterminate. Depends on too many characteristics of
too many devices.
If I had to pick one-and-only-one, I'd bet the cubic
inch of air in front of your nose on Jim's outcome.
Max continuous amp ratings are usually in the ballpark.
Surge amp ratings are ???

One of a couple things can happen. Might trip the circuit breaker
on the generator. But more likely, the thermal overload on the
side of the compressor will trip, and then reset after a minute
or two. So, the compressor on the refrig will keep trying to
start but never quite will start.
A hard start kit for the fridge may help. Some appliance guys
(like me!) occasionally use a boost kit for when the starting
components of a compressor go bad.

sent an email to the manufacturer asking about that, but they never replied.
My Honda EU2000 produces 13/16a, but the breaker is 20a. On an overload the
engine "pauses". I don't know about the Yamaha, but I figured it was the
The generator will not stall. The refrigerator will
cause a undervoltage problem during startup. Since
your generator is close to having enough power the
fridge will start, although it will struggle initially.
Historically, refridgerator motors do not play well with brown outs. When
you draw more amperage than the source is able to provide, you get a brown
out. The voltage will simply start lowering. Many appliances will not
function. Some will recieve damage.
For damage to occur,the "brownout" has to last for some time,while the V
drop for a motor startup will only last for a brief time.Probably less than
Motors are pretty durable.
So,if your fridge has microprocessor controls,then there could be a
