Technical Question What is the difference between running watts and starting watts?

An inverter changes 12vdc to ac. If it is 35 k it may be 35000watts. Therefore it needs that many watts or more to run it efficiently. Check with a manual for information on how many watts it needs. Most average homes need 10000watts or 10kilo-watts. If you are making DC Volts you need to hook up an AC LINE INTO YOUR VACATIONER and this will give you standard a.c. for refrigerator and overhead lighting. With that 35k watts if that is so you may need a 240 VOLT AC HOOK UP.. Some trailers use AC and some DC . Mine has an inverter but I think it uses120 volt AC . Some VACATION Homes have DC possibly 4 -12volt batteries or more but those batteries are each possibly 300 AMPS at. around 14.5 volts DC. Watts =VOLTS x AMPS . 14.5 X 300 = 4350 X 4 =17400 Watts or 17.4 k watts . 120 VAC input times 15 AMPS = 1800 watts standard a.c. But with 240VAC x 25AMPS = 6000 watts. Along with those 4 batteries it would have plenty of power to run it. If the Dc was hooked to an inverter it would produce a.c. Instead of DC. Inverters are all different so check the wattage being output and input.

Watts to volts doesn't translate as they are different units to measure things. Watts is a power measurement while volts is what is trickling through the cable. You could have 12 volts at 6000 watts or 240 volts and 5 watts, depends on usage. If it's for a car audio amp, it will be generally 12 volts to power it which at 1200 watts means it will run at around 100 amps current according to ohmslawcalculator.com

What is in a Watt.
Although Watt should be a dimension of power (current times Voltage) most manufactures give numbers you can't use. They always speak of maximum power. That number only can be reached in a laboratory and is measured on a clean resistor. They try the lowest resistor (not an impedance) the amplifier can work with, without blowing the end stage.
Then they put a free marge to tell you it should have a musical power of xxxx Watts. The output differs for speakers of 2 ohm, 4 ohm or 8 ohm. But there is not one speaker with an impedance over the whole audio spectrum.
Just read something over audio and power amplifiers.
The output has nothing to do with the quality of the sound. I have heard 15 Watt amplifiers perform hundred times better then some kilowatt amps.
Even if the manufacture says the amp is 1500 w it could be within legal limits and fir the amp is measured and can't deliver 100 watts of real power nobody can do a thing, because the watts could be the musical power. and that is a free invented non measurable measure. I don't even want to start over distortion, because the cheaper amps do produce more distortion, than music. If you use it for a sub woofer that is no problem, because you feel more than you hear.

Sorry for this big story and not saying what the real output is, because nowadays nobody bothers measuring amps like this.
The more serous audio magazines, will put some test about amps, and you should read one or two test to know what I mean about the worth of watts in audio.

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.

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.


GENE

With inverters and generators, the power rating is usually off by about a quarter.
Watts and volt-amperes are totally different and sometimes inverter manufacturers don't tell about the difference. A basic rule of thumb is to take whatever the inverter is rated for and knock a quarter off. So, in your case it would be best to assume a maximum rating of 1500 watts.
Also, inductive loads like drillers (electric motors) usually have a start-up current 3 to 8 times the rated operating current. Meaning that 100 watt driller will draw 300 watts to start up. So, if you use an electric motor rated at 700 watts, its startup load would be 2100 watts or even more and thus trigger the inverter overload switch. Hope this helps you.

You will need to replace the cooling fan with a brand new one

By lowering the WATTS from 550 down to 300, you may find the P.C. starts shutting down or restarting, as it does not have enough power to operate everything inside the tower. You need to add up all the WATTS on the different things running on power ( i.e. Motherboard, Graphics Card, RAM, Fans, Sound Card,USB plug-ins, HDD, CD/DVD drive). You maybe not have all listed but by lowering the power might be not worth it to be honest.

At the bottom of page 3 of manual (link provided below) in the "Technical Specifications" section, indicates it has 800 watts of cooking power. The 1200 watt rating is the total electrical load on the circuit that is required to run fans, lights, etc. in addition to the 800 watts for cooking.

I hope this helps!

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)
