What size of an inverter generator would you need to run a MacBook Pro?
Look on the AC power adapter and read its rating in watts. You will need an inverter with at least that output capacity.
No. For that, you need an inverter or a generator.
You need a power inverter or a mechanical motor-generator.
You will need to find a inverter, or you can use a DC motor coupled to a AC generator.
Yes, but it would have to be a pretty big and expensive wind generator. You would need an inverter to produce at least 500 watts of 3 phase power. Unless you also had some big batteries, you could only run your motor when the wind is blowing!
To convert direct current to alternating current you need either an inverter or a motor-generator set.
You need at least 6 times the wattage. Call Samlex.com. This is for the surge and heat fuser. This is too expensive so I am going for a portable generator.
You would need at the minimum a 56 KW generator. In reality you would need a 60KW.
Is it better to buy an inverter or a generator if your power requirement is 4000-5000 watts and run air conditioners?
I assume you are speaking about inverters that make Alternating Current out of DC batteries, like those that are frequently used in vehicles, typically for camping or construction Most inverters are smaller than 5000 watts, but if you could get one, for air conditioning you would need a lot of battery storage because I assume you would not just run the air conditioner a few minutes. I would think the generator is the better way
Depends on the wattage of the cooler. 800 watts would be a small cooler I think. You need to check the cooler specification before connecting it to the inverter.
You need to read the fridge's nameplate to get the power rating you will need to supply from the inverter.
When using the Inverter the CCU can be adapted to the users needs. A regular 12 volt battery would work on any small devices.
A 300 watt audio system means it has a peak power of 300 watts but the average power might be only a fraction of that, perhaps 5-10 watts. So it might run off a car battery, with an inverter to supply the correct voltage if needed. <<>> A 300 watt public address sound system will operate very nicely from as small as a 500 watt AC generator. A 1000 watt generator will give you more… Read More
That load is 72 kVA so you would need a generator of 80 kW driven by a motor of 120 hp. For continuous use you would need a 100 kW generator and 150 hp motor.
It depends on the inverter. Keep in mind that the average starting current of a motor is four times its running current, so the inverter would need to be able to handle a 54 Amp transient. (Or higher, depending on design margins.)
It varies a little depending on your brand, but the back of the television should give you a fairly good indication for power consumption (about 221W for a Sharp 42" LCD TV). Then you'll have to check out to see if TV can handle a Modified Sine Wave (MSW) supply or if it needs a Pure Sine Wave (PSW) supply. You don't want to plug in your 42" TV and burn it out. The PSW… Read More
You can visit Honeywell.com. They have a generator calculator, so you can calculate what generator would be best for you.
To get 220v from 12v, you will need to step up the voltage. One option is an inverter, another option is a step-up transformer, a third option is a motor-generator set. There are other options. It all depends on your power requirements.
A battery by itself will only supply DC output. You would need a method to convert DC to AC, such as an inverter, in simplified terms: an electronic circuit which has an oscillator to create the desired frequency then amplifies it to the desired magnitude output. Another way, which I don't know if used anymore, is a motor-generator set. A DC motor's shaft is connected to an AC generator's shaft, and the output is taken… Read More
Yes. You can use lower voltage to power higher voltage loads. You need a step-up transformer, an inverter, a motor-generator set, a charge pump, or some similar type of device.
The generator would be a 230 v 3-phase generator with a rating of 18 HP or 13.5 kW. If the motor has a power factor of 0.8 the generator would need to be 17 kVA.
A DC to AC inverter takes a DC voltage input to a AC voltage output. So if you have a 12v battery and need to run a 120v AC tool or something. All you need to do is plug a inverter to your battery and plug your 120v tool the the inverter. Takes all there is too it.
What do u need for a dodge truck if u are needing to run a tool that is 120volts a inverter or converter
Can you run a 120 volt 5 amp window ac unit off a 12 volt deep cell battery with a 12 volt dc to 120 volt ac power inverter installed on the deep cell battery?
You "could" run a 120V 5A window AC unit off a 12V deep cell battery but, assuming 100% efficiency (something you can never get), you would need an inverter or motor-generator set and 50A out of the battery to run, and maybe 5 or 10 times that to start.
Yes, a three phase motor can run on a DC supply. You will need to provide an inverter, or a motor-generator set to do so. (In practical terms, the answer is no, because the costs will be high for any kind of significant power.)
If my house has a 200 amp line what size generator would it take to run the house and have the same power?
Your house runs nowhere near 200 amps, so you need to make a list of appliances and fixtures that you use, or that you will need while the generator is running, and add their power consumption together. Add some extra capacity for growth and so the generator is not always at full power. Then talk to dealers about generators with the amount of power you need. To run the house on a generator with the… Read More
Depending on your needs I would compare them side by side. Do you need an optical drive among other things? Is mobility a higher priority? Weigh them out and decide.
A 5 kW generator would turn it over but if the full 30 hp of mechanical power is needed, that would require about 30 kW of electric power from the generator.
you need to get a lot of horses
Depends on the refrigerator. There should be a sticker on the inside of the fridge that lists the power requirements. Make sure the generator rating is RMS and not peak. You can use a generator wattage calculator to estimate the total wattage you would need to power your "must have" appliances during a power outage. This way you can estimate the generator size (in watts) you would need to power them.
First you will need a three phase generator. Mathematically there are 746 Watts per horsepower, but I like to use 1000 Watts for ease of mental calculation. This would mean you would need a 30 kW generator. If using 746 Watts per HP, you would need 22380 Watts, or 23 kW. Make sure this 23 kW is the normal load rating of the generator, not the surge rating! 30 kW would provide more of a… Read More
Does a propane tankless water heater need electricity to ignite Currently have an off grid cottage and a 9000 kw generator Do you need to turn on generator for the tankless to work?
All tankless gas wwater heaters have an electronic ignition system, with one exception, Bosch made one that used the flowing water to turn a small generator to ignite the burner. It was a complete flop and i believe was discontinued. One thing you might concider is that they really DONT use much electric, a car battery with a power inverter will run it for quite a while
Hi, I own a MacBook Pro 15" unibody 2010. I don't know what you mean by the best, but I would recommend it highly. The MacBook Pro is a durable, powerful, and portable laptop. It is the perfect solution for someone who want to do video editing and such things on the go. If you only need the computer for web browsing, making Youtube videos etc. I would recommend either the MacBook or the MacBook… Read More
What device would you connect to the primary of a transformer so that it would give an output when dc is used for the input?
You would need an inverter http://en.wikipedia.org/wiki/Inverter_%28electrical%29
Just wondering what you mean... Perhaps you meant a 1,000 WATT generator, in which case the answer would probably be "No". That's not enough capacity to run most freezers at start-up. If you actually did mean a 1,000 AMP generator, you would need to specify the voltage and amps or the watts of the generator and current draw of the freezer in question before anyone could answer your question. Since most home chest-type freezers operate… Read More
The MacBook and iPod Classic are not compatible items. You are comparing Apples to Oranges. If you need a computer, buy the MacBook. If you need a music/video player, but the iPod.
No. You need a three phase supply to run a three phase motor. If you only have a one phase supply, you could use an inverter or a motor-generator set, but by the time you did that, it would have been more cost effective to simply get a one phase motor, or (in the bigger case) upgrade to a three phase supply.
Renting a generator instead of purchasing one can save money if one does not often need a generator. While it is of little use in emergencies due to not knowing when it would be needed, renting a generator would be a useful way to obtain electrical power on a camping trip or cross-country drive.
Apple sells only only one version of the Macbook Pro 15". You can upgrade the processor, ram, hard drive, and display if you wish. If you are using this Macbook as a student, I would recommend you get the Macbook Pro 13" base model and save yourself $600. It is all a student will need. However if you are looking for the best laptop you can get for your own use then the 15" is… Read More
There are 3 things you need in order to perform MacBook data recover: Apple MacBook, MacBook file recovery software and hard drive (or external disk).
Apple has a feature called Continuity that gives your MacBook Air the ability to make a call to a mobile phone. It does require a MacBook Air or Pro with the Yosemite OS, and the iPhone would need to be iOS 8.
It all depends on what you need it for. If most of what your doing is taking notes, web browsing, word proccessing, etc, then the MacBook Air should be fine. If your an enginering student, doing HD video editing or other heavy processer work then the MacBook Pro would be better for the long run. With the newer Apple laptops you will need to max out the ram as you won't be able to upgrade… Read More
That power is 22 kW so the minimum generator size would be 22 kVA.
The offline UPS is in standby mode. The charger is maintaining the battery, but the inverter stage is not running. Power goes from input to output, bypassing the inverter. In this configuration, the charger and inverter design is less, as the charger is usually in trickle mode and the inverter does not need to run continuously. On power fail, the inverter starts up and takes the load. There is a glitch in output, a few… Read More
If the service is single phase 200 amp then you would need a, W = A x V, 200 x 240 = 48000 watt generator. Since there are no 48kW standard generators you would have to use a 50 kW generator.
You would need a static inverter. You can easily find these in marine (boat) or car parts stores for smaller applications. For larger applications, you would have to buy from an industrial supply company. You could also build your own inverter, but this would probably cost you just as much as buying ready made, would not be safe, and would not be as reliable.
Amps x volts equals watts...200 amps at 12 volts would be 2400 watts...add a few more because. the inverter efficiency is not 100 percent...
If the service is single phase 200 amp then you would need a, W = A x V, 200 x 240 = 48000 watt generator. Since there are no 48kW standard generators you would have to use a 50 kW generator. If your home distribution panel is 100 amps then a 25 kW generator will work.
You would need to use a transfer switch. The generator will hook up to the transfer switch and then the transfer switch to the panel. Usually you would have an emergency breaker panel to hook up to since a 7000 watt generator wouldn't be able to power up most entire homes. You would pick which circuits you would need in an emergency situation and bring those into the emergency panel. The transfer switch makes sure… Read More
You would need to check the rating of the pump.
