Q:I am looking for a portable propane generator primarily as a home backup. I have a couple models in mind but have no clue about the quality. they seem to have good reviews, but wanted to ask in here anyways. i'm looking at the Sportsman GEN7000LP or Powerland PD3G8500E Tri-Fuel. anyone have experience with either of these? or can recommend a similarly capable brand/model?

Why a propane unit? Propane cost more per gallon that gasoline or diesel. If you have access to natural gas it would make more sense.

Q:I need a specification of the inverter and battery that will work for 5-6 hours with around 10-14 laptops connected to it. Can any one please help me.

You would need to be more specific. Multiply the watts of one laptop power supply by 14, then get a more powerful invertor. e.g. 14 x 50 watt laptops 700 watts, get at least a 1 Kw invertor. It is difficult to predict how long a particular battery will power an invertor, a 1 Kilowatt load will draw a huge current, about 50 amps from a 12 volt battery. If at all possible you would be better off using a petrol or diesel generator and extension leads, as the size of battery needed would be enormous, you would need a no. of 12 volt large 12 volt batteries joined together, or one battery and one x 100 watt invertor for each laptop. You might also consider using a battery to power a DC to DC convertor for each laptop. For example one laptop could use a 12 volt, 50 AH battery and a 12 to 20 volt convertor, this will probably run a 50 watt laptop for 6 hours. I say probably because the only way to know for sure is to try it out. For the price of 14 batteries and 14 convertors you can probably buy a really good silent 1 kw petrol generator. This will be smaller, lighter and probably safer than 14 x 50 AH batteries.

Q:What is the most important parameter of diesel generator

rated power factor (COS): refers to the motor rated power factor.

Q:What type of diesel engine diesel

Ambient temperature above 0 degrees with 0# diesel.

Q:I have a generator in the building I am working on. It appears quite dated, but its stats are as follows: it’s a 415 Volt 3 Phase Diesel Generator.On the plate of the generator:415V3 Phase640KVA520KWPower Factor 0.8902 AmpsSo my question is:We are testing the generator to its full load, now my load is at power factor 1. Would I be correct in assuming that because my load is power factor 1 that the full load of my generator is 640kW not 520kW.Or is it that my actual power loading is rated at 520kW, but that load is allowed to be inductive or capacitive to 0.8.Because it says 900 amps on the plate I am therefore under the assumption that regardless of my load characteristics, as long as I do not exceed 900 amps there should be no problem. Or is it a case that my load can only be 520kW and the highest I can allow the phase to go out is up to 640kVA.Hope that makes sense, ill edit if not. Thanks for reading.

While your generator will handle the amperes as either KVA or KW, unfortunately, the KW rating is is the rating of your driver. You are driver limited, not generator limited.

Q:I Have an ASUS A8N-SLI Deluxe motherboard with the chipset fan going at over 6000 RPM, an AMD Athlon 64 4000+ with the CPU fan at about 3000 RPM, and a GeForce 6200LE with a very high pitched fan that's dead annoying. To cut a long story short, my PC makes way more noise than it should be, now I don't have any case fans installed but that shouldn't mean that it has to make this sort of howling, believe me, if you were sitting next to it, you'd understand where I'm comin from, it's like tryin to sleep at night with a diesel generator in your room while it's downloading stuff. The fans shouldn't need to spin that fast as the average temp is about 30-40 degrees Celsius across all the components. Anyone know what I should try? Cheers Sam The Bam

I had this problem, and one day, my computer just stopped. in fact, its sitting in the chair behind me. but it ended up being the CPU fan, put some thermal paste between it and your motherboard. Check your local Best Buy or Office Depot. but whatever you do, DO NOT TRY TO UNPLUG THE FAN! i did and my computer caught on fire (its not funny :[ ). And as a matter of fact, i can sleep with a diesel genereator beside me fine, im used to the noise, i sleep with a fan. ffs.

Q:I have a 1992 Toyota Tercel that sits in my yard. It ran at one time, but has been driven so little that it now no longer starts. Had this problem one time before and paid someone to fix it. They replace the fuel pump to get it started again. Other issues are lost title, back left tire seems locked, and busted windshield.I hate to just trash this car and wonder how difficult would it be to turn the motor into a backup power generator for my house? Is it feasible? One of our sister companies at work has a diesel engine that acts as a backup power for their computer room, so I wondered if I could possible do the same for my home.Any suggestions?

Almost anything is possible if you spend enough time and effort on it. The real question is: Is it worth it? What you have is a crappy motor in a junk car. Take it out of the car remove the transmission. Attach the engine to a motor mount like an I beam box frame that you have fabricated. Attach a generator unit to the end of it. Then you need to fabricate a speed governor of some type to keep the engine running at 1800 rpm to generate 60cycle power. Lets not forget your crappy high mileage engine. It might work for a while but after all of this effort you will probably wish that you rebuilt it. OR You can just buy an 8KW generator for $2000 JUNK THE CAR.

Q:I own a 2300 square foot home with an upstairs and downstairs heatpump. If I wanted to buy a generator to use in the event my power went down what size should I shoot for. I would like to be able at a minimum to provide upstairs heat (1000 square feet), maintain the fridge and provide minimal light at night. Basic survival type stuff. Also how much fuel would normally be consumed running for 24 hours?Thanks I know this is vague so generalities are fine.

The whole key to this answer is fuel. If you live where you can get lp or natural gas to the house then go with the generac whole house with automatic switch. I mean a constant supply like city gas or propane. NOT FROM A TRUCK. The trucks will not run if your in the middle of a hurricane or other types of storms If you have to use propane from a tank, rent the largest one available. A 300 pound tank will only last 4 days under full load. Gasoline is dangerous and to hard to keep fresh.

Q:and what would allow the most crop turnovers of growth? Hemp???

yes as long as the generator has been retro-fitted to use biofuel and not petroleum. A diesel generator would do this best Probably algae would be the best thing to use as you can get several generations a month from it. hemp takes a long season to grow and really only the seeds would have enough sugar to be used to distill biofuel. Beets (which you can get several crops a season from as they are fairly fast growing) would be far better than hemp for fuel as you want high sugar or starch crops (starch can be converted to sugar). But why run a generator on biofuels when it would be easier to run it on solar or wind

Q:What is the most important parameter of diesel generator?

Rated power (PE): refers to the diesel generator set rated output in the case of the maximum power output, the unit is kW (kw) or MW (MW)
