Question about Coleman Powermate Powermate 5000W Generator

2 Answers

Generator Wattage I was wondering if anyone knows if a 2000 or 2500 watt generator would be a good fit for running a computer, monitor, cable modem and firewall. I guess i don't want to have the generator go into a brownout condition if i have too much equipment for it. Thanks...

Be very careful with anything electronic. These generatore are not regulated electronicaly, only by the RPM. I would invest in a voltage regulator for voltage spikes and high voltage but you will still have to watch for "brown outs" (low voltage) which will burn out electronics as well.

Both sizes will handle that stuff as long as generator maintains a constant rpm. otherwise you run risk of low voltage or voltage spikes which cpu will not handle for very long

Electricity current eratic


The output of the generator is listed as a constant voltage and a maximum current or wattage - that could also be thought of as capacity.

Typically, it would be rated for 120 or 120/240 volts for generators sold in North America and the wattage could be as low as 3,000 - 5,000 to substantially more than that. If you were to look at the watts or amps while a connected light bulb were turned on, you would see the voltage stay at 120V, but the amps would go from 0 to .833 Amps - and the wattage from 0 to 100 (assuming a 100 W bulb). Next, connect a toaster - again the voltage stays at 120, but the amps and wattage would jump from .833A and 100W to 8 or 9 amps and 1100 watts. As soon as the toast was done - the amps and wattage would drop back to .833A and 100W. The same could hold true for a well pump or air conditioner that is connected to the generator.. these devices turn on and off automatically as determined by a pressure switch or thermostat. Seeing a wattage or current that fluctuates is normal as the amount of power needed from the generator changes as the devices turn on and off by them selves.

Also, it is not unusual for motor operated devices to draw 2 or 3 times as much amps or wattage during the first few seconds when starting as opposed to what it uses when running.

What faults can a change over switch caurse between the generator and the load


One consideration is how many circuits and how much total wattage is being used when the generator is in service.
"Gas Powered Generator GG2300 2300 Watts Surge 2000 Watts Continuous Output 10 Hours of Run Time at Full ."
This is a relatively small generator with 2000 watts output, so the problem may be that the generator can not handle the wattage demand. You can get a pretty good estimate of the wattage demand by adding up the wattage of everything , all lights, appliances, etc that's being powered by the generator. If the total wattage is greater than the output of the generator (2000 watts) then the generator is too small.

I have a kenmore refrig/freezer. Full load amp is 6.5 , 60 hz and 115 volts. I have a generator that will take 1100 watts with 1500 peak or surge watts. I heard that refrigerators use more electricity or...


Hello,

The calulation of max wattage is going to be 750 watts at start up and be around 500 on normal running wattage after start up so a 1100 watt generator should be fine.

The generator kicked the breaker of and was smoking and smelled like electrical


What type of load (electrical) was hooked up to this generation?? If the surge voltage and current was exceeded above the generator maximum for any length of time. There problems, it could be the regulator, insulation burnt off the windings.


I am taking a guess here. Now, 7100 Watts is it typical surge wattage. This mean that the generator will deliver 7100 Watt (voltage times current) this is know as the power factor. The actual operating load would be 6800 Watts and I would even operator the generator at its peak wattage. Something in the neighborhood of 10--15% less the peak wattage. Therefore a good positive theatrical Wattage would be 5800 to 6350 operating wattage. Then this generator would run all day.



Just remember Ohm's Law. Current plays a big factor in loading of a generator while the operation voltage is at 120 AC Volts. Example: electric motor; Now electric motor when starting will pull three time its operation current. Operating current for a 1/2 HP AC motor is 6 amperes but start this electric motor will require 18 amperes. This is one reason why they starting capacitors on smaller electric motors. Larger three phase electric motor can literal stop a generator cold...in its tracks. It put such a large demand on the generator it stops the engine powering the generator. I have seen crankshaft break because the generator could handle the heavy current load.



Remember, any time you are running a small gas powered generator. All ways figure what the load and surge current load will be before hooking up any generator. Normally this is figured in VA (volt/amps). Wish you lock. GB...stewbison

Can a 220volt floor sander be run off a generator


Hi Glen,

Welcome to fixya!

You would have to check the capacity of your generator. If it can handle 220 volts and the amp rating of the floor sander does not exceed the amp rating of the generator, you should be good to go.

Good luck.

When you accept this solution, please place a vote for me.

Thanks,

I am interested in a generator that can light a 3-bedroom hse and a chauff cutter


Your cutter machine may use more power than your whole house depending on the size of motor. A one horsepower motor 115v will use about 3000 watts to start and about 1000watts to run. To estimate how much power you need, add up all the watts that you will use at home and add to that estimated wattage of the cutter motor (motor will use 3x rated wattage to start plus loss of power thru the extension cord). Buy a generator that will give you needed power and still have a 25 percent reserve. If you need 2000 watts on a continued basis, the 2800 watt may be good, however I would be more comfortable with a 3500 watt if the price was right because of the cutter machine. I would consider converting the cutter to gas power and buy a smaller generator to save on gas since you will be most likely running the generator far longer to power the house. Good luck

We have a Valsi 5500 watt generator that isn't putting enough voltage out to run everything in out small travel trailer. It runs the lights but doesnt push out enough voltage to carry the A/C, microwave,...


How long have you had this generator?
Has the generator worked on all of these loads before?
Model 5500 is a 5500 Watt generator which could easily be 5500 watts (Peak) and not continuous.

Your AC is an inductive load.
Your lights are resistive loads

An inductive load can cause issues when starting due to an increased current demand at start up that some generators cringe under. Do the lights flicker or are they stable? I'd say your diodes on your stator are working if you have light stability but you haven't provided nearly enough information for a detailed solution.

I'm sure you have enough voltage but you aren't getting enough current to run specific loads. How many watts is your AC? How many watts for your microwave? Both of these units demand a great deal of energy to run and when you place too much demand on your generator, it will choke it out and eventually, will cause damage to the generator. You may consider getting a beefier generator with a greater amount of wattage output.


Seeing these specs online and noting what you are trying to run, you have an undersized generator and need to get one that can produce a greater amount of running wattage (as well as peak wattage).

Kenmore top mount refrigerator, 18 cubic feet. how many amps doe it use. question is for purchase of emergency generator. spec Plate states 4.5 amps, is that accurate? Refrig is 115 volts, 60 hz


Good day,
That sounds about right, however if your generator is rated in wattage the amps times volts won't work.
On an induction unit, such as a refrigerator, the wattage is volts times power factor times amps.
Nominal wattage should be around 375 watts. However, during auto defrost the heater will probably be around 450 watts.
As well, locked rotor amps on starting will be about 4 times running amps approx. 18 to 20 amps. so your generator will have to be able to handle that.
The short and long of it is give yourself wiggle room.

Honda generator runs great,voltage output is good but when load is applied motor cuts off. no breakers tripped or resets tripped?


check your load..the generator is carrying heavy weight when you are going to load a high wattage thats why its RPM will turn slowly and have the possiblity to stop it...It MUST be needed the the given wattage of the generator is greater than the load you apply.for example:when your generator's specification is 3500 watts,tehn the load you are going to apply is i watts to 3499 watts only..
