How do you size a generator for a motor?

Make two lists. List the appliances you want the generator to run when commercial power is available. Next, list the appliances you want the generator to run when commercial power is NOT available. Determine the wattage of each appliance and then add them together for the first list. Repeat this for the second list. This will give you total wattage for each list. This will help you determine the size of the generator needed to power your devices when commercial power is available and for when commercial power is not available.Understanding the wattage values of each appliance is important for correctly choosing the wattage values to add together to get the total estimated wattage needed to power your appliances.If all of your loads are resistive, such as incandescent lamps and heaters, you simply add up their wattage to get a total. However if you have electric motors which will cycle on and off or appliances like a heat pump or an air conditioner, you must take into consideration the required starting current of these devices. The start up current of these devices can be up to 6 times the running current.Starting Watts are the power the generator can produce for short periods of time.Running Watts are the power the generator can produce continuously.Here is an example of how to determine generator size:Question: I am considering the purchase of a standby portable generator to power key appliances in the event of a power loss which sometimes occur during winter snow storms. Do I just add up the total number of watts required by the appliances I want to run? In the event of a winter storm interruption of electricity, I am looking to keep the refrigerator/freezer running, along with the blower motor of a pellet stove, a few electric lights, and a radio. All else can wait until power is restored!Answer: The total estimated wattage of 1840 watts is needed for the radio (15 watts), the motor (575 watts), and the refrigerator/freezer (1250 watts). To this I added 500 watts for five 100 watt light bulbs for a total of 2340 running watts. Next I added the starting watts of the motor to the running watt total of 2340 watts, to get the total estimated wattage of the generator needed to power all these appliances simultaneously. For example, assuming the starting watts needed for the blower motor are 3 times its running watts (3 times 575 watts = 1725 watts), so the total estimated wattage of the generator needed to power all these appliances simultaneously is 2340 running watts plus the 1725 starting watts of the blower motor, for a total of 4065 watts. The generator needed to run all these appliances simultaneously would need to have a maximum power output of at least 4065 watts.Note: The maximum power output is also called short time watts, peak watts, maximum watts, surge watts, and starting watts. It's helpful to keep this in mind when reading portable generator wattage ratings.


How to compute the minimum load of 16 MW generator?

A generator, rated at 16 MW, should be able to continuously supply a load of 16 MW. You don't need to compute its 'minimum load', because the minimum load will be zero watts! In other words, you can run the generator with no load whatsoever if you wish to waste fuel.The point is that the power supplied by a generator is determined by the load, NOT by the generator itself -so it is important that the generator is capable of supplying the maximum load applied to it. A generator's 'rated power output' simply tells us the maximum load it is capable of supplying.


Can a 5.2 kw generator run a 2.5 horse power pump?

1 hp = 746 watts 2.5 x 746 = 1825 watts or 1.825Kw The Generator is large enough.


An electric generator produces 10 megawatts this amount is equal to?

10MW is equal to 10,000,000 watts or 13,404 HP


How much elecricity does it take to power a generator?

A few Watts more output than one appliance used or a few Watts more output than The TOTAL ADDED POWER RATING OF ALL THE APPLIANCES CONNECTED TO THE GENERATOR. Usually Professional Electrical Engineers work using a simple calculation called THE DISTRIBUTION FACTOR, But to simplify matters for DIY just ADD all of the Wattage ratings together of all of the appliances and then ADD say about 20 Watts and the total is the required Wattage rating of the Generator.

Can a 120V generator run a camper's air conditioner?

Well all generators with a few exceptions produce 120 volts. What will determine if a generator will run your air conditioner is the number of watts the generator will put out. You need to learn the wattage needed by the air conditioner and also learn the max watts put out by the generator you have (Assuming you have one already) it the generator produces more watts that needed by the AC unit you are good to go. Not on the other hand if the generator you have dose not produce enough watts or you do not have one then it is a matter of buying a generator with the wattage required by the AC unit in your camper. Now if you are going to buy one I would also determine what else you would like to run from the generator (in addition to the air conditioner. Figure out the watts need by these items add them together with the watts needed by the AC unit. Then buy a generator big enough for your needs.

You would need at the minimum a 56 KW generator. In reality you would need a 60KW.


What size generator do you need to run a 7.5 hp motor?

Conversion from gas to electric should be 750 watts/hp So 7.5*750=5625 watts These are running watts so that is a bare minimum. Depending on the application it needs much more starting watts (up to 3 times for a compressor). Generator should be no less than 8000 watts, maybe more if you work it hard.

How large a 110 volt generator is needed for a 40 amp 12 volt battery charger?

amps*volts=watts 40 amps *12 volts= 480watts watts/volts=amps 480watts/110volts=4.36363636amps So you need a 110 volt generator that can produce about 5 amps as a bare minimum. To take into account system heat loses that occur when converting power consider doubling it to be safe. (this is over kill but the advantage is that your generator is not working at full capacity at all times)

How do you assess generator capacity for domestic use?

The first thing to realize is that the little store bought generator in not going to run the whole house in a power failure. These types of generators usually output from 1500 watts up to about 8000 watts. To power a house and all of the appliances a generator in the range of 30000 watts would be needed. What is needed is a list of priorities of devices that need to be used during the power outage. Locate the nameplate of the devices and start totaling up their wattage. If the wattage is not stated on the label multiply the amperage times the voltage which will result in watts. Watts = Amps x Volts. Once the wattage's are totaled add 10% to the list and that is the size of the generator that you should be looking for.
