800w generator what will it run

BrotherBart said:. Singed Eyebrows said:. It is kind of baffling why a generator would produce the choppy second picture. I can understand a modified sine wave inverter doing this, the generator rotor should cut the flux in a pretty controlled manner though. Later New Member. Jan 30, Retired Guy said:. I did a lot of research before buying mine I wanted to be able to power my tv, computer, tivo, fridg, etc the fridge has all sorts of electronics.

I assume the dirty power is just do to undersized equipment, jumping brushes, govoner adjustment of the engine and taking and unloading loads. I figure it is inherent to small generators, and that is why they sell inverter generators.

I heard a lot of stories and buzzing power and problems associated with regular generators and a few from this type of inverter generator too. For me I did not want to be worried about what I plug into my generator.

With this I am not worried. Figure out what you need the generator to do, find the generator you think is right, read your reviews. You cant go bad that way. You can find osciliscope readings for most any generator on the internet, you just have to look.

You were right Maverick, I was able to find scope outputs for my champion genset as well as a more typical other brand genset. Before we get all excited about that clean Honda sine wave perhpas we should see what the grid power looks like. They don't use inverters. Wooddust Member. Aug 31, 85 Missouri. Regardless what you do anything from HF is garbage.

Well, I don't think my watt generator from Harbor Freight is garbage. Similar threads R. Harbor Freight5 ton elect splitter on a generator problem.

Before deciding on a generator, it is important to consider ALL the appliance you may want to operate, how many will be used simultaneously and the TOTAL current consumption at any one time. Most appliances have a descriptive plate stating the current, usually in watts.

Various electrical applications have very different power requirements, so it is essential to understand each particular need. For example TV sets, cookers, kettles and filament lamps have resistive loads, this means that their start up and operating currents are virtually the same - and as stated on the manufactured descriptive plate. Buying the right generator can seem like a formidable task. But in just a few easy steps you can effectively and confidently decided and choose which generator is right for you.

Motor starting is an important consideration when buying a generator. Keep in mind that induction type motors, like those that run sump pumps, refrigerators, compressors, pressure washers typically require 2 to 3.

Please note that power tools using a universal commutator do not require any additional start up power. The calculator below lists tools and appliances you may want to use with your generator. Short answer is that there are enough watts in you generator to run it, but possibly not enough to start it as it needs often many times the running watts when the unit turns on. Please check with your manufacturer or certified electrician, which I am not. Good luck.

Hi Ray, I am so confused! Ok, I am looking to run a watt portable heater in my car for my dogs when I am parked for a extended period of time. I am looking at a surge watt generator with a average. Will this power the heater? I am not connecting anything else, and I cannot find anything on the surge requirements of the heater. Can you help please? Thank you. Hi Jeff, Normally portable heaters do not require surge watts.

However you are asking too much of a generator to power an appliance that requires watts where the running watts is recommended at watts. It is generally not recommended to use the additional surge capacity of your generator to power an item ongoing.

You may cause your generator to shut down leaving your dogs in the cold. I know its difficult to find portable heaters at less wattage. If not you may have to step up the size of your generator.

That would keep from having to carry around the generator and fuel. Ray, Thank you for the clarification and help. Basically just small tailgating stuff. You saved me some cash and my dogs appreciate that! Your the best! I need to power to televisions and a speaker what size generator would I need. Or what factors do I have to consider? So lost…. The first thing to do is take the watts required to run each of the items you want to power.

If you expect to run each of these at the SAME time, you must add up the wattage requirements. Usually only appliances with electric motors have a surge requirement. This should be enough to run the items you mentioned as well as be useful at other times as well. If you wanted to replace power in your home, you will probably want at least watts to watts or more for general usefulness to power more items at the same time.

I am looking at purchasing a watt generator for my home. I would need it to power the heat pump and refrigerator and aome lights.

Will this be big enough? Here is my best answer. First, is the watts the running watts or the surge watts? You will want to make any determinations based on your running watts. A refrigerator will typically need watts supplied by the generator including the surge watt requirements.

Lights will take very little, depending on their wattage and how many you plan to power. The question is in the capacity of your heat pump. I know very little about heat pump requirements other than that they can be as large as 10, watts. You will be able to find out if you can check the plate near the serial number. Otherwise contact the manufacturer with your model number. Add up all the watts of anything that you want the generator to power. Keep in mind that you can alternate the things you turn on to keep the total below the running capacity of your generator.

Hope this helps. Hi Paula, There are a few factors to consider. After reading this article, you know that you need to determine how many amps each of your devices require. Lights take very little. Is your refrigerator in a motor home? A camper? Remember, refrigerators require surge watts as they cycle. You can disconnect your fridge while you run other cooking appliances for a short time and keeping the door closed , which might take that many watts as well.

Hello Elmo, More important than the cost of the generator is the capability of the generator in Volts and Watts.

There are some things that you need to know about your chop saw. You can get a generator with surge watts and you should be just fine. You need to buy a generator that provides that many watts. But add more watts up to to cover the surge requirements of your saw. Sorry to give YOU the math lesson. Seriously, thanks for the good info!

Hi Russell, The answer will depend on a few things. First the requirements of the appliances that you plan to power. For example, Your lights are determined by what wattage they are.

Are they all 60 watt? Then your requirements for just the lights assuming that they are all on at the same time is between and watts. Your TV probably needs around watts. The heater will have a wattage requirement. Find that out and add that. If it has a fan, it may require more as would any appliance that has a starting motor in it. So your fridge definitely has a cycling compressor in it. Guess watts if you plan to keep it running continuously.

If you schedule what is running at the same time you may be able to. Be safe, get the They are a bit louder, but not that much more expensive. Hope that helps. You will first want to know how many tons for your central AC unit.

A two ton unit should be fine with a 12Kw generator. You may be at its limit if you have a 3 ton AC. Good Luck Ray. Hello, I have a small concession business that I am trying to start.

Collectivly all my major machines add to watt requirement. What size generator will I need? Thank You. Assuming some of your machines have motors or something that will require occasional surge watts. Smaller and you will be limited to what you can run at the same time. This answer is beyond my knowledge. Maybe one of our readers can help. Hello, if I need to run a medium sized deep freezer for about 10 hours, what size generator will I need to keep it running? Hi Melissa, Not knowing your amp requirements for you particular freezer, this is only a guess.

Check the information plate and see how many amps your freezer requires. Multiply that by volts and that will give you the watts required. Especially if you plan to open and close the freezer often during this 10 hours. Remember though, a freezer can keep its contents frozen for several hours with no power with the door closed. So it will depend on the size of your freezer and why you need 10 hours of power, whether you need a generator at all.

Let me know if you need more information. There are alot of assumptions in my answer. Guys if I need to power a steamer that is Watts.. Hi Ramon, You will be better to get a larger unit.

You may have trouble with it bogging down or shutting off. With a larger unit you will have a more versatile generator that can be used for other things that you may not be thinking of right now, but will be glad when you do.

Looking at microwaves that are w or w. Thanks in advance for any assistance. Hi Sylvia, You have important information in that your microwave is up to watts. This is the minimum number of watts that the appliance needs to operate. Please remember that certain appliances those with motors require more watts than their running watts when they start.

The same will apply to your fan that you want to run. An inverter generator is the choice here if noise is an issue. They are a bit more expensive though. Make sure that you operate your generator well away from your van. The Carbon Monoxide emitted can be deadly. Would a output be suitable or something larger, thinking my character will have the small freezer already up to running order before being plugged in initially. Thanks Jan. Remember a freezer is very efficient in keeping things frozen, when the door remains closed.

Should you open it, keep this to a minimum and your contents should remain frozen for several hours. What kind of generator will I need for the chiller. Tracy, I assume that the chiller works and that the generator work.

Simple assumption but important. Your frigoglass chiller probably needs more power. Hi there, I am not sure if this is even possible, but I am wanting to cool a 10x20x8 ft pop up garage tent.

First, I was wondering if this could be done with an BTU portable air conditioning unit. Second, what size generator would i need to power this and would it be relatively quiet? Let me know if I can provide any further information.

Are you going to have your AC in the tent, drawing air from outside? It seems that this would not be well insulated and the cool will dissipate easily. That aside: Find out how many Amps your unit needs. You mention how quiet. The larger the unit, the noisier it will run. Consider a quieter inverter generator but it will cost more.

It should go without saying that the generator will be run away from the tent, right? Take the higher number of amps required between the two. Multiply this by the amount of volts your generator will produce probably Double this number to cover the surge and get a generator that can supply this amount of watts.

What size generator do I need? Hi Jeff, Without knowing the amp requirements of all you want to do, it is difficult to know if this will be enough. Make sure, that even with an inverter generator, to protect your laptop when operating from this generator with the other things running at the same time. Pls, can 1. So if you have a volt generator, multiply with total amps, say 20 amps, then you need watts just to run them. By this example, watts will not be enough.

So, I have a small air compressor. Will this run the compressor? Hi Brian, That might be a bit undersized. Your watt Honda probably runs at watts. If your item runs at 10amps, you need watts just to run it, not counting the surge watts that it will require on startup. I need to purchase a portable generator as opposed to a heavier standard. Do you think a start up run watts portable generator will do the trick?

John, it sounds like you should have enough if your unit needs 5 Amps or so. I am thinking about an induction cooking plate. It is labeled as watt.

Can the generator handle it or do I need to purchase something else? I understand that I would be maxing out the generator, but I have 3 solar panels at this time. Want to use it for camping or survival. It may fluctuate below what you expect. Ray, Can I damage the generator by trying the Watt cook stove or could it possibly damage the cook stove?

How would I know that it is OK? It is an induction plate. Spoke with the company and asked them to consider a slightly lower Wattage and they seemed interested. Time will tell. Hi Sharon, If the generator bogs down or shuts off due to too much load, it is not good for the generator repeatedly. I suggest looking at its manual or contacting the maker again.

As a rule of thumb I always recommend a larger generator capacity that you expect to need. Hello… I have watts mitsubishi generator. Can it handle a deep freezer watts and a light bulb 20 watts. Seeing you table, a deep freezer watts needs surges watts as well. What is the correct size watts from a generator i need to buy? The table are estimates only. But from what you tell me watts should be enough to run your watt freezer and a light bulb, even with the surge requirement of the freezer.

Remember, the freezer does not need to be run continuously in an emergency. With the door closed it acts like an ice chest, keeping things cold. You can use your generator for other purposes periodically.

But you have to be diligent in your timing. It is recommended to go with a watt generator or larger. If you already have the generator see if it will operate under working conditions.

There certain times during the year that I need to power my sump pump during power outages, not many times but enough to create a lot of concern. I have a Zoeller pump which operates at 9. I am looking for an inverter generator that would provide the power needed to run my sump when needed but would also provide power for other recreational activities tailgating, camping, computing, TV, etc and be easily portable.

Am I in the ball park with those numbers? The Honda in parallel provides watts Any thoughts would be greatly appreciated. Sounds like you ran the numbers right. Yes there is a slight loss of power when you run tandem, but it you have excess, you should be ok.

Good idea for the tandem where you can use only one for your lighter needs. For instance i want to run the most items but not the whole house. So a refrigerator, a portable air conditioner, and a tv. You would probably be at or very near the limit due to this uncertain requirement which can be hard to determine.

The ac unit says it consumes at V When the compressor kicks in it needs around 1. What size generator would i need for this? Thank you in advance for your feedback. A generator is a several year investment, and who of us can see our needs years into the future.

Hi have just brought aw pure sine wave generator will it have enough power to run the hair straighteners. If they are simply a flat iron, then possibly so. As you know blow dryers can use a lot of power. A watt blow dryer may not work when you turn it on due to extra surge watts needed. I have a machine which is rated like w 2 hp v… To run that machine what capacity generator i need??

Please guide me. Your machine with a motor requires an amount of surge watts which can vary depending on what your machine is. The most logical way to go in my thinking with this information is to take into consideration that it also requires V. That will determine in part the power output of your generator. You might consider a — watt model with V capability. Make sure that you consider your outlets on your generator and your machine. I am setting up an ice cream van in an RV and will be using a separate freezer when operating, volt.

The double that number for surge requirements and you should be OK. For example 10 amps time volts equals watts. Double that and you get watts as your requirement. Remember, get as many watts as you can afford.

Consider an inverter generator if noise will be a factor. Good luck, Ray. If you plan to use the generator in close proximity, inverter generators run more quiet than standard generators. Inverter generators are also enclosed in a housing which dampens the sound. I am in an electric wheelchair that has a 24 volt battery charger that I hook up to my chair to charge it every day.

I would also like to run a refrigerator intermittently in case of power outage but also I have a small deep freezer as well. I was thinking an watt generator is what I probably need.

Also I live in an apartment I do have a porch that during a power outage I can put the generator on and run it but then do I have to buy something like an extension cord that will come into my house to be able to plug the refrigerator and freezer in? Thanks for any help you can give me. Hi Patrick, Thank you for reaching out. If I just take into account the uses that you mention, i have a suggestion for you.

For your refrigerator and freezer, you can probably get by with a to watts generator. They can be unplugged periodically. When you plug in your battery charger in to the generator, the freezer can be unplugged for example. Also a factor for you is noise and proximity to your living area. A standard watt generator is LOUD. It could disturb you or your neighbors. This is another reason to get a smaller unit.

You also might consider an inverter generator which is more quiet, and less heavy. Consider that an inverter generator is more expensive per equal wattage.

This is another reason to downsize your generator wattage to the range. All of these should work: W standard generator more than you need regarding power and expense W standard generator enough power and less expensive W inverter generator enough power and less noise, but expensive.

Finally, you mention running the generator from a porch with cords. Yes, but make sure that the generator fumes are well away from your living area. Outdoors in a well ventilated area is best. Never in a garage. This will determine the length of cord required. These can be pricey as well.

Hello im trying to figure out which generator i would need for my project. Im wanting to run a small window unit, mini fridge and microwave, and Tv. As well as charge electronic devices. In other words im going to be living in a converted rv for a while. Will a watt inverted generator r do this for days at a time? Hi Ty, Remember you will not be running each of these mentioned at the same time. You can figure that when you use your microwave, you can turn off your TV or unplug your mini fridge just remember to plug it back in.

So the short answer is probably yes. I can sort my electricity usage by monthly, daily, and in 15 min. My question is:- If my peak running watt usage in KW for a 15 min. So here is my thinking. Hi Michael.

Yes the ratings are for the generator output at any given time. Also, during emergency situations, one would rarely use as much power as during non-emergencies as you would normally cut back. Add up the total usage that you expect to use the generator for and double and triple check this need. You may find that you can get away with a smaller choice generator. But you are wise to not expect to tax your generator to full load.

Double check with a electrician before you make your final call. I plan on building appx sq ft home. At the most per 12 months of electric use came down to kw per month which averages out to be 2. I also went out and looked at my breaker box and added up the total amps for Any time I speak to someone they only add more confusion about what is needed.

So my question is this: all things being equal is there a way to figure my needs? Hi Carla, yes it can be confusing. First question for you, are you planning to live off the grid with the generator being your sole source of electricity? Or are you planning for when there is a power emergency and you are without power for a length of time? But if you need temporary power, then there are some basic considerations.

Your breaker box in your new home will be sufficient to run your home. Refrigerator, freezer, sump pump, whatever. Most power needs in your home are not continuous. If each light bulb was watts, if they were all on at the same time, you would need alot of power. But use them one or two at a time and your needs are much less. You could turn off your TV when you want to use your microwave. Make sense?

Your estimate of watts is probably enough. I have a 1. Would this generator do the job. It may be a bit on the small side, Rob. Especially with the startup requirements of the compressor. Not that much more to get W. LOL I read everything and have been educated and entertained. And easy storage for my truck. I drive 18 wheelers. Check out the Yamaha for the higher end and the Earthquake on a lower end. Both reviewed on this site. Are you planning to use the generator in your 10 wheeler while on the road?

You might consider a solar generator which will store enough power to run your tv and gaming system when you use it. AND it will be silent operation. Ray, you are one of a kind! A boon to people who is a novice on portable generators, like me. Now following your formula, I have a 25 cubic ft of refrigerator, with a wattage of Have you heard about it?

What do you think, since I will only be using it for emergency back up, that may happen maybe every 3 or 5 yrs, or not at all. Hi Eligio, Yes, watts is enough for your example.

And YES you can find less expensive brands with near equal consumer satisfaction. Yes WEN is a good company. The are however VERY handy to have around even in a non-emergency situation. I need to power 3 X 12, BTU split units air conditioners 1 refrigerator and 1 deep freezer, with some lights and 1 television. Should be enough. But still you may find you have a bit left over. Hi SMS, It depends on how many amps your list will draw. I also depends if all the items that you mention will be run at the same time.

Your fridge will probably draw the most if it is a normal size. Look on the plate on the back to see how many amps it needs to run. Next is your water pump. You can always unplug your fridge when you run your pump if not needed all the time.

For your computer, you might want to consider an inverter generator to keep your electronics safe. Are your fans on the roof, standard ceiling fans? Do you need to run them all at the same time? The first thing you need to do is look for the power draw on each and add them up, and if you need to run them together. Hi, I just purchased a watt generator just to get me by for the winter for some lighting in my warehouse.

I only hooked up three 75 watt clamp lights and they do not power on. I can run my angle grinder and my jigsaw with no problem. What would cause the lights to not work? I tried a 40 watt bulb and that powered on but seemed to be pretty dim.

You might have a problem with the outlets. When running the power tools, is it from the same outlet? I have a commercial Kalvinator 18 ft Freezer and 18 ft Refrigerator, they both are Volts with 5 Amps start up each for a total of 10 Amps. Run Amps is 2. I did the calculation of both for a total of watts. Would a watt inverter portable generator operate both appliances?

Your calculations seem correct Kevin. Just make sure of the running watts of your watt generator. The rating of is usually the surge watts. I am configuring a food truck that has total wattage of all appliances I am considering a KW generator that only has 50A plug. Please help me to understand. Hi James, your requirements assume that you will be using ALL appliances at the same time. Typically 50Amp generators would be sufficient under most circumstances.

Calculate your best estimation of what will always be running including surge watts. Periodic usage of other appliances can make up the difference. I need to power 4 heating elements at 8 amps each. I cannot use a generator because it needs to be indoors. Is there a way to generate the power needed without using a gas generator? It is needed in a hotel room situation. Hi Nick, Do you need the power continuously or periodically. You might consider a battery bank that you can keep charged through solar?

Hurricane season is approaching. During One we were without power for 10 days. We have a special generator plug hooked up to our electrical panel. What size generator should we buy?
