Question about Coleman Powermate Proforce 6,000 Watt 12 Hp Portable Generator #PM0106000

A: Running watts are the continuous watts needed to keep items running. Starting watts, are extra watts needed for two or three seconds to start motor-driven products like a refrigerator or AC unit.

no

ac units are 2000 watts minimum, washing machines are 1500 watts minimum, microwave is what is on the plate and start at 650 watts but most are 2000 watts

the 2400 is the peak out put for start up of fridge , washer etc and the running wattage will be 2000 watts or less ( duty cycle )

to run more than one of the nominated items at once you will be needing a 5500 to-6500 watts unit

they handle a start up surge of 6500 watts ( larger one) and will comfortably handle 5500 watts run full load

it works like this , the plate on the gen set is the surge short time load capacity of the genset and not the duty load which is 500 to 750 watts less than that plate wattage

for example your 2400 is is surge rated at 2400 watts but duty load is less than the 2000 watts

many people make the mistake of buying a gen set that looks big enough but do not calculate the maximum load capable on being put on the gen set

fully loaded uses more fuel /hr

wears out faster

has power surges as the extra load cuts in and the motor struggles to get back to required rpms for voltage and cycles

will not cover extras like lights ,

a much large gen set will take it all in it's stride , no power surges, better economy, less stress

talk with an electrician , do your maths on everything you wish to run and that which you forgot about then add 1000 watts to the duty cycle and that will be close to the gen set you require

what is meant by the run time

an 1850 watt unit will run indefinitely if the out put is around 1750 watts but probably 5 minutes at 1850 watts as that is the max wattage for surge start ups ( electric motors switching on as in fridge compressors, drills, compressors)

if you are running it at around 900 watts constant then a tank(20 ltrs) of fuel will probably last 8 hours

5,500 watts should do it because you need to consider the starting watts of your air conditioner and not the running watts, but if you want to run some other things you might as well buy an 7,000 watt genarator because the price isn't that much more depending on the brand.

I have a Briggs and Stratton 8,500 starting watts. I live in SouthEast Florida and I use it whenever we have a hurricane. I have it hooked to a transfer switch and it works everything except for my electric range and my three ton air conditioner. It will also work my hot water heater, lights, fans etc. I have only used it one time and it works great.

I plan to buy a whole house generator with the capicity of 25,000 watts so if you know anyone that could use it (even in it's original box stored in my garage, no rust or ware and starts on the first or secong pull) and they are in or near Boynton Beach, Florida then perhaps we could make a deal.

As you have not provided me with the information I requested I'm going to have to take a few guesses here Bob. You could be overloading the generator. You can't run a 10,000 BTU air conditioner off of a 1000 watt generator. You need to look at your load, (what you are trying to power), and determine how much power it needs. Almost everything has a tag somewhere on the device. Most don't give watt requirements. But they do tell you, how many amps the device pulls, as well as the voltage the device needs. So you need to do some math here. Volts X Amps = Watts. So if we have a 120 volt device, that pulls 15 amps, we need 1800 watts to power it. But it gets a little more tricky than that. Motors are often rated at what they pull while they are running! But it can take two or three times more power to get them started. Example... A motor rated at 10 amps, using 120 volts will be 120 X 10 = 1200 watts. But it could take 2400-3600 watts to get it running. So in theory a 3000 watt generator may die before it can start that load. Heating elements are also power hungry! Let's say you have a small 800 watt generator, and your just trying to run a simple coffee pot! Well the heating element in a typical coffee pot pulls 1000-1500 watts. A hair dryer or microwave oven rated at 1000 watts, is the power they produce, not the power they consume! So a 1000 watt microwave may pull 1600 watts of power to run. Most non US generators are highly over rated as well. I certainly would not trust a Harbor Freight 3000 watt generator to actually put out 3000 watts of power. Not that they are bad units, I would expect their numbers to be under PERFECT conditions. Temperature, humidity and altitude also play a part! Your 3000 watt generator is going to put out more power at 50 degrees, at sea level, than it is at 7000 ft in the mountains at 100 degrees. So my "guess" Bob, is that your just asking more from the generator than it can produce. Picking out a generator is not as easy as it looks. "Hey that one is $1000 and this one is $300! They both make power! What's the difference". The difference is what do you need to run! "Heck I'll just get that 50,000 watt unit"! Yeah you can do that too, but you will never use that much power, and you will burn way more fuel than you need to. My other "guess" is that you have a governor issue on the engine. As load increases the gov will throw more throttle to the motor. My generator has an option to run full speed or on the gov. So it will idle and burn less fuel while I am hammering in a nail, then go to full power when I trigger a saw connected to it. Lot's of factors involved here Bob.

This is called hunting and it is because the load sensor is not working

This generator is a 5KW model. This means it can supply up to 5000 watts of power, total. Not all devices list the watts they need to be provided - instead these devices list the power they need as volts and amps. This can make it hard to determine what the actual watt requirements are for the device.

Overly simplified, watts is equal volts times amps (watts = volts x amps). A single 120 volt light bulb that uses .833 amps consumes 100 watts. If you checked a regular 100 watt light bulb with an ammeter, you'd find it does indeed draw .833 amps.

Working the formula a different way, we can learn how many amps this 5000 watt generator can supply at 120 volts, too. If all the loads you need to connect to this generator are 120 volt types, that means the total amount of amps the generator can supply is 5000 watts / 120 volts = 41 amps purely resistive loads (like a toaster or light bulb) maximum under ideal conditions. There is never a time when ideal actually happens, and not all loads are purely resistive - many are inductive. Inductive loads are motors (like your A/C), fluorescent lamps, computer power supplies, etc. - so figure more like around 30 amps total instead.

If you try to connect devices that require more than 30 - 35 amps, the generator will probably have problems trying to supply this load for any longer that a short length of time. Additionally, motors like those in A/C compressors draw significantly more power when first starting and can cause the problem you are describing. Try running the generator with loads other then the A/C to see how well it can supply the load(s). Or try running only 1 A/C unit and other non-A/C loads.

What I'm trying to tell you is that you may need to do some active load management to be sure that you aren't trying to get more power out of the generator than it is capable of supplying. You may need additional generators or swap this one to a larger size to handle the load properly and safely.

I hope this helps & good luck!

clean carb old fuel is no good

Your gen. is a 2000 wt max 1000wt running out put. Means it will start your jackhammer but will not maintain the wattage to run it long. You are using the max it has to put out. So let me try to explain - 2000 watt max output works like this - We will use a fan as an example. A fan sitting still and not turning takes more amperage/watts to start. that is called lock rotor amps. So lets say the fan is a 1000w to run. 2000w start the fan turning then it takes 1000w to keep it turning. Your gen. can start the fan but not keep it running it is using all it has to put out, now if that fan only uses say 750 w running watts you have some head room to keep it running with out things getting hot. Hope this is clear as mud.

Alternately,

• Turn-off all lights first.

Run your pump or water start motor.

• When the motor is running,

Turn on the lights , one at a time.

a 6250 watt generator isn't as powerful as you might think.

Here is ohms law for Alternating Current. It is different than for Direct Current

AMPS= WATTS÷(VOLTS x PF) I=P÷(E x PF) A=W÷(V x PF) WATTS= VOLTS x AMPS x PF P=E x I x PF W=V x A x PF VOLTS= WATTS÷AMPS E=P÷I V=W÷A VOLT-AMPS= VOLTS x AMPS VA=E x I VA=V x A HORSEPOWER= (V x A x EFF x PF)÷746 POWERFACTOR= INPUT WATTS÷(V x A) EFFICIENCY= (746 x HP)÷(V x A x PF)
