Generator recomendation
« on: October 25, 2020, 01:13:52 PM »
The wife has mentioned that we need a generator and being one who tends to like things like this, I am looking. But, I don't know anything about gensets, so, what should I be looking for? Its just the two of us, two small chest freezers, and a need for AC due to medical reasons. Also, keeping a refrigerator running and a few lights going and phones charged would be nice.

So, who makes a good one?

How much should I pay?

I can figure out watt ratings and work back from there to find something in the right range, but am I missing a safety buffer?

This is what I am looking at:
https://www.northerntool.com/shop/tools/product_200664805_200664805?cm_mmc=Bing-pla&utm_source=Bing_PLA&utm_medium=Generators%20%3E%20Portable%20Generators&utm_campaign=Powerhorse&utm_content=750137&msclkid=3ad89dd146a51d7881c6c251a51075c0

But I have never bought from Northern tool, and if I am dropping that much cash, I don't want to deal with a huge hassle if it doesn't work as I want it too.

Thanks in advance guys!

Oh, one other thing, I hate Honda products and will not buy one.

This is never an easy subject simply because of the number of variables that one needs to consider.

1) Are you installing an auxiliary panel with a transfer switch? (this cuts the main house panel and provides a separate auxiliary panel for generator power
    circuits) I highly recommend you do this install so you can easily run needed circuits in your house, AND you don't backfeed into the power mains during an
    outage. It's also much easier to run your household without stringing miles of extension cords all over the place.

2) When you say "needed AC" are you talking about a window unit? if not, then running central heating and/or AC will require a higher amp 220v output
    capability and that usually means a generator in the 6-8KW running range, but you need to check the specs of the AC compressor to make sure it will
    start. Some will require a hard start box (aka boost kit) to make it work with generator power.

3) No budget generator will run your entire home, and you need a list of your power requirements (watts and amps) so that you know for sure which appliances
    can be run on what specific circuits. Knowing this info will help you eliminate the power hogs during an outage and will prevent circuit overloads and/or
    tripping breakers at the panel or the generator. For example -- a simple little Keurig style coffee maker is a huge power hog, and can trip a breaker very easily
    if the circuit is already loaded with a refrigerator or other kitchen appliance.
    Make a spreadsheet and enter all the wattage and amp requirements per needed circuit to see where your potential overloads are. Then balance the loads
    accordingly. Once balanced, you can have the auxiliary panel and generator unit sized to fit your spreadsheet.

Good luck!!

I`d like to know how many kw`s a bloke needs need?

Is the need enough? Or does the want suffice?

I am just guessing but my experience tells me you need something in 8000 watt range. To run a couple freezers, a fridge and an ac unit.

What you're likely to "miss" is surge capacity for starting motors. The AC is probably the largest although that'll depend on what kind of AC you have. If it's inverter driven mini split or high end central it won't have any significant inrush.

The A/C will be the big load. A hard start kit will help the A/C but the generator is still gonna have to pick up the end rush current and carry it. If you’ve got a newer inverter A/C unit it’s a lot easier to start those. The easiest way is to do a limited transfer switch. Where only some demands are sent to generator power.

I know you said no honda.

But, I have a northern tools 8000 watt. Cage, tank and generater head made in usa. Powered by a gx390 honda. It has been rock solid. I have had it for close to15 years and it has sat for at least 6 months and always started on the first or second pull. It powered my farm for a week after an ice storm when I bought it.

Do you have a well?

What kind of heat?

Sump pumps?

Is this for use when you are at home, or to run the house when you are away?

Do you have natural gas or propane?

Will your wife have to start and connect it if you are away?

You linked to a 2KW generator.  That is on the smaller side, but if 2KW will meet your needs, then that is what you want.  Larger ones use more fuel, and therefore more trips to the gas station.  In that size I would recommend an inverter generator.  They are quieter, and use less fuel.  Most non inverter generators are two pole generators and therefore run at 3600 rpm (LOUD) to make 60 hertz AC.

My house came with a Generic natural gas 16KW genset.  It is set to start when the power goes out.  I was away for a few days, and my neighbor told me it ran for 9 hours.  The generator was making 16,000 watts for 9 hours, and I was using about 20 - 50 watts the entire time.  They sell a cell phone interface for it, I might have to check into that.

and a need for AC due to medical reasons.

Did you mean Air Conditioning or Alternating Current?

Any 240 volt loads, or all 120v?

Thanks, everyone, but maybe a little more information is needed for you guys. Basically, after the power shutoffs in California over the last few years, my wife and I wonder if Oregon will do the same thing, which wouldn't be surprising considering our governor. So, we want to make sure that the food we put away will not spoil, and the small AC unit will keep me cool, as I have MS and high temps are a killer on me.

So, The AC is little more than a window unit, although it looks better. 1270 watts. And this is the only one I would worry about inrush amps, but that is not listed.

Two freezers, 5 cubic feet each (only things that will fit in the basement) 300 watts altogether

Refrigerator, which is only listed as 4040KwH per year. But, breaking it down is 45 watts I think. Not sure if I did that calc correctly, it has been a while since HVAC trade school.

Other than that, I just want to be able to power a light or two and recharge phones and laptops.

We would only be worried for a few days at a time, so a lot of the plans for adding a panel are a little overkill for what I want. Again, it is just to run the basics and enough to keep food from spoiling. The stove is gas, so that isn't an issue. I can make coffee the old fashioned way pretty easily, and the wife drinks tea. No well, no sump pump, nothing like that. But I do like the idea of a quiet generator.

I hope that helps

I would only run it on extensions as that allows me to control what actually gets

champion 93723

dual fuel gas/lp, 3500 watts inverter, 30 amp rv plug  and receptacles. should ran a 15000 btu camper ac,

a little pricey at over 1100 dollars but should give lots of options. 20 lb, 30 lb 100 lb lp tanks and gasoline.

With proper load management you could get by with a fairly small genset. Not everything needs to run all at once. Run the AC and fridge for 23 hours a day and run the Freezers twice a day for the 15 or so minutes they need to keep everything frozen.  The smaller the set the easier it is on fuel. bigger sets take more fuel even when lightly loaded. My wife ran our house with a 4000 watt set for 5 days on less than 10 gallons of gas after hurricane Harvey. No AC tho.

The one SKfarmer recommended is a good size. Sams has some killer deals on smaller machines too.
