The best thing about my generator setup which is functionally the same as yours is that it is MAGICAL. Most of the times I've used it, right after selectively shutting off the water heater (I'm all-electric), dragging out the generator, connecting the cable, getting things cranked up...wait, I need to fill the tank completely up first to get maximum runtime, and usually all of this is in a downpour, and finally switching over the breakers, the MAGIC happens and line power immediately comes back on. It's turned into a meme in my family. "Dad! Get the generator out so the power will come back on!"

[@diyhvacguy]

[@Freight_Train]

I hear you. After rigging a series of hidden heavy duty extension cords to various parts of the house to use my generator, our first power outage lasted 15 minutes. I was so disappointed the power came back on and I wasn't able to really test the whole system.

[@shenmisheshou7002]

I live in Texas and after the big freeze 2.5 years ago that killed about 600 people, I decided to put in a generator inlet and interlock kit after that because I never wanted to be near freezing to deay again. I went with an inverter generator, which is much quieter and much more fuel efficient (though if you are running on NG, that is not so important), and while my generator is not big enough to run the AC even with a soft start kit, most of our extended power outages are in the winter and spring where keeping central heat is more important than AC. This past winter we were out of power for 3.5 days and I was one of the only people in the entire area that had power. My inverter generator is 5000 watts continuous, and this was more than enough to run everything in the home with the rare exception that I could not run both the microwave and toaster at the same time (we have a full fridge, mini fridge, and small chest freezer, and all of these were kept running as well.) It worked so well that five of my neighbors decided to put in 5000 watt generators with an inlet and interlock. They know they may never need them, but they now have the ability to keep their families worm for days at a time if the power is ever out again. If I lived where there were hurricanes, I would probably go with a standard backup generator, but for these 3-4 day outages, the interlock setup is fantastic.

[@SaltySouthTexan]

Killed 600 people? In TEXAS? I went through the SAME freeze and didn’t hear of no 600 people dying. Unless you mean nationwide? Texas lost 28 people according to Tx officials

[@Emmilythecat]

I bought one of these from Costco 3 years ago. Ran it on propane the whole time. Had to run extension cords. I do not have the generator inlet box yet or a natural gas outlet yet. It is one of my goals to install soon. When we had our hard freeze, we were able to run medical devices and keep our fridge going. Very happy with our generator.

Thanks for this video. It is exactly what I needed to see in addition to the Soft Start and Power Surge videos. We just bought a small house in Central TX where power outages are the norm in Summer and in Winter.

[@Nolaman70]

My 4 ton went from inrush of 120 Amps to 40 Amps for reference. I have a similar setup but don't run my Central A/C with my portable generator. It does run my entire inside breaker box. I do not have a main breaker or shutoff on the outside box, pulling the meter is the only way to disconnect power to the main outside box. I just shut off the inside box, outside, then run the inside box from the generator. My Central AC is on the outside box. Works great for me as I can run everything except Central, Oven, Hot Tub.

Living in Austin, TX. The past two winters have produced storms that knocked out our power for days. I invested in this generator (bought for $600) and a shed to store it in. We've had to break it out once since then, but by the time my son and I got everything hooked up and running the juice returned (of course). At the end of summer we have a pool being installed and I'm going to include running an inlet box to the main panel when the electric is installed for the pool.

I have virtually the exact same setup. AC soft start and a Firman Tri-Fuel. I opted for their 10kW (when running on gasoline) generator because I have 2 older refrigerators and 2 older deep freezes as well. I've never had to use it, but in testing, it will run my entire house. While using a portable generator is a little bit of work to get the power back on, the generator is not limited to backup power only. I can use it for other purposes.

[@Bassguitarist1985]

One thing to note with soft start devices, they lower the inrush current at startup. THEY DO NOT LOWER THE RUN CURRENT OF AN AC COMPRESSOR. Soft start devices do not save your money (in reality its very negligible) in electricity bill costs, but they greatly save your compressors life span minimizing wear and tear since it's not hard starting with a partially for fully locked rotor from the pressures inside. Great video!

[@Watchyn_Yarwood]

just curious, if soft start is beneficial that way, why don't the AC units come from the factory that way?

Bro. That is a bada** setup. Literally all you need. Once past the initial cost I'd say it pays for itself within the first couple times of use. Maybe even after the first time from a peace of mind type scenario. In gonna price it all out and see what's what. Good clip

This is a great idea, I wish I knew about this before my own budget whole home generator build. Fortunately for me, my generator runs my home including ac without this great device but I wasn’t sure until last week. I still may upgrade so thanks again

[@ahent1975]

Please remember all generators are not created equal and to run electronics it is safest to have one with a Total Harmonic Distortion (THD) of less than 6% or it can ruin computers, DVD players, and other sensitive electronics.

[@TrungNguyen-jf2sg]

Yup that’s true. The only generator I can find out there that is 3% THD is a Westinghouse IGEN 4500DF but it’s only 120v. My outdoor Unitary Heat pump is a Coleman HMH7 with an inverter board. My natural gas furnace is a 2 speed variable ecm so it also has a board that requires good sign waves. I was going to buy that Firman he’s got but I think the THD on it is too high. I’m an Hvac tech as well and did this research with a help from the supplier tech support. I’m surprised that Firman powered up his minisplit as well but how do you guys feel about wear and tear on those boards with that high THD? Bad thing about this Westinghouse is it’s only 120v 30amps so it’s only good enough to give me natural gas heating but no AC is we’re out during the short summer here in Seattle. Great video, just my thoughts and also if anyone out there that knows any portable Generators like those that can do 240v 30amps any type of fuel with a low THD roughly 3-5% is what I’m trying to find. 👍

I spent about $3,300 for everything including the electrician to install 50 amp outlet, natural gas conversion kit and hose, plumber to install gas outlet, MicroAir soft start and Duromax 13000eh generator. It ran a 4 ton AC just fine. This guy is only powering a 2 ton AC.

[@rwstarke]

FYI .... According to the T07571 manual, the maximum is 31.25A. I have the same generator. I have seen a 42A peak at startup using the Micro Air soft starter, but it is usually 36A. Then the A/C runs on 13A. When the A/C starts, I still have the refrigerator, HDTV, desktop PC, LED lights and other small devices on without a problem. I think that the generator is producing more watts on NG than what is stated in the manual.

[@attimus02]

Are you running a FIRMAN generator like he has or an Inverter? I have the same FIRMAN and was told not to run electronics off of it due to the dirty sine wave of electricity that could harm sensitive electronics

@@attimus02 Same generator, same model. It is not pure sine wave. I do have four UPS's on my HDTVs, computers, routers, external hard drives, Xfinity X1 box and have not had a problem except the UPS's will beep and click when using the generator. I have a stupid power strip plugged into the UPS battery backup side with items plugged into the strip. All I have to do is move one plug to the surge protector side. And then turn off UPS. Surge protector with EMI/RFI Filter will still work. APC PowerChute has a sensitivity setting which may help with the clicking. If I don't use a UPS then I do have APC surge protectors. My Fisher & Paykel Dishdrawers will beep. As a backup, I have two 1408Wh and two 666Wh power stations, and eight 100W rigid solar panels which I made into four suitcases to set up in the back yard. I could also use the generator to charge the power stations and use on anything sensitive.

Now I’m thinking this is an awesome supplement to a more expensive setup too for whole home battery backups. If the power in the battery starts to get low, you could maybe use this to recharge your batteries for completely uninterrupted power supply over long term (cheaper too since that generator uses 72cuft/hr when completely idle but 101cuft on full load).

Something VERY IMPORTANT that was not mentioned. You need a 240 v generator not 120v. Most generators are 120 volt. After buying 2 cosfco generators, a parallel kit and paying an electrician $1500 to do the electrical work to put in an inlet and an Interlock kit I found out the hard way, that my two firman generators would only power "every other circuit breaker". The electrician confirmed that the only way to power the whole house is that you have to have a 240 volt generator. Unfortunately 240 volt generators are expensive and I lost a lot of $$ since I waited too long before finishing the project and had to sell off my firman generators. Sure costco allows returns but if you return too many items or too many big items you risk getting your membership terminated.

[@dewholdingsllc1050]

Thanks for the content. Gathering information. I knew about the soft start boxes from the RV world and how they allow RV AC to run on much lower amps. Including a small generator. Good to see the generator is working to power Home AC. I have a NG pipeline at a new property but not electric service so I’m having to plan on doing a non grid tie solar array and a permanent NG generator tie in with a solar power cell for storage. Electric power equipment is in extreme shortage right now in USA and really expensive because of the shortage and the electric coop says it’s a year or more out to obtain a new line. They require a 25kva outdoor rated transformer and I have not been able to locate one in this state and one I did find in South Dakota was $7300. If I buy the equipment and the cables to run the lines I don’t get reimbursed, just donating the equipment in order to get a new line. I personally would rather invest my money in a NG generator and solar array and storage system. Keep these low budget low energy content coming.

[@shenmisheshou7002]

The soft start does not reduce the running amperage, only the in-rush that lasts about 1/3rd of a second. If the AC takes 2000 watts to run, it can take up to 6000 watts to overcome the locked rotor amperage, which is what the compressor needs to overcome the static pressure in the system. The Locked Rotor Amperage (LRA) is written on the spec plate of the AC. For example, my 3.5 ton unit has an LRA of 109 amps, but once running, the system (including the circulation blower) runs about 4000 watts but even with a soft start, the draw starting draw is too much for my 5000 watt (6250 peak) inverter generator.

[@JohnSmith-uy7sv]

You're a lifesaver. So thorough. Not that it's a big deal, but could you use one for the hot water tank? I always turn ours off in a hurricane and if we need to use it, turn off all the lights and run it. More important to have A/C and lights than anything. I just have to see what size ICM870 I need for my 3.5 ton unit. Thanks again. 🙂

[@truthseekerKJV]

There is always a downside to running the HVAC through a generator. The power just isn't the same as grid power, but it's better than sitting in a hot house with no lights.

[@dammitbobby283]

The problem with this setup is it's exposed to the storm that knocked out the power in the first place which means the person starting the generator is exposed. Nobody wants to stand in a storm. Also the generator will get soaked by rain.

[@mwredfern]

This is a great video! Can you answer a question for me? Are you running the fridge also? How many fridges. And if needed, are you able to run a tv and a gas oven with this unit. Also, water heater. The reason I ask, cause I feel like there’s some misconception out there with how big a generator is needed. I have a townhome, with 2 ton AC, 2 fridges, water heater, electric washer dryer, 2 tvs, 2 computers, a Wi-Fi router and of course lights throughout the house. Not everything will be ran at the same time. So I feel like something under 10000 is big enough. Thanks again for this awesome video. Look forward to your reply and anyone following the comments.

Excellent video! How would you know when the grid power comes back on?

[@donarndt9525]

You forgot one very important thing. If you are connecting to your circuit panel you need to unbond the ground from the frame of the generator. You don’t want two locations where you bond the neutral and the ground. There is a jumper on the generator you need to pull off. If you are using a cord right to the source, not through the circuit panel you have to put it back on.

Good Demonstration, BUT.....Be very concerned about potential damage you can do to sensitive electronic equipment ( AC , TV, Computer, etc.). I own the same generator and according to data posted on the Firman website it is rated at 11 to 14% THD. This is way higher than what is recommended for sensitive electronic equipment. The power supply for sensitive electronics should have < 5% THD. I would hate to damage the circuit board on my inverter based AC ...or even my two speed compressor as it would be a very costly fix. I like this generator, but wish it put out cleaner power. Any thoughts on how to address the PQ issue with this generator? I live in South Louisiana and ran multiple window units with the generator and didn't have an issue. Sure would be nice to be able to run one of my central AC units.

[@Bassguitarist1985]

There is no way to clean up high THD at this size of generator. Its simply not economical in cost. You would need a sizable load reactor device that is matched to the loads in your house. This would basically absorb all the higher harmonic voltage/currents above 60HZ and convert it to waste heat but leave the 60hz power alone for your loads to use. Over time high THD can and WILL cause damage. The bigger enemy is actually voltage surges since portable generators at this level while many have brush type AVRs or brushless capacitor excited, the regulation will never be as "tight" as utility. A heavy load starts, the engine momentarily drops in speed before the engine governor responds, and the AVR drops in voltage and takes a moment to recover the voltage back to the preset level. The AVR can "overshoot" the recovery for a very brief time where high voltages can be seen by your devices and damage them. To your point thats not good. Sufficient surge suppression like MOVs in a circuit can help absorb these transients sacrificing themselves before your inverter based AC.

@@N-M424 not necessarily. I have tested generators with an amp probe meter and at half a load for a 6,500 watt generator with a 3000 watt resistive loan I've seen THD as high as 16%, and would only get worse from there. It comes down to the build quality of the powerhead.

[@Bassguitarist1985]

@@N-M424 it was a Generac GP6500. Full load it was closer to 20%. Doubtful it would be that low for the Firman.

[@Bassguitarist1985]

@@N-M424 that is what the firman website says about the model yes, but Id be willing to bet with a resistive load that THD would be more.

[@Bassguitarist1985]

@@N-M424 agreed. Between James Condon and myself we are testing THD one portable generator at a time!

Great video and info

[@benh580]

Awesome setup. My power went out for 8 hrs the other day. I have two ac units (upstairs and downstairs) I was able to run everything except the upstairs ac with a 12000W generator. I wonder if i added a soft start for both ac units if i could run them both. One system is a 2.5 ton and the other is a 3 ton.

Hi, thank you so much for this video. We just bought the newest version of the Firman from Costco with Tri-Fuel. We have plumbed LP in our community and I am setting up the Firman as you have with a quick connection to this gas system. We live in Maui in a community north of the fire we just had. I realized we were totally unprepared and luckily found this generator after the fire and we are quickly becoming prepared. I would just like to ask you what is the best way to estimate how much gas we would be using from the community system to only power with extension cords. We would be powering for now only our deep freezer which is 7 cubic and a refrigerator 13 cubic and a Starlink satellite. In the future, I would love to set it up like you have to have a connection to the house but electricians are hard to come by right now during this crisis. Thank you for your help and God Bless.

[@jeremygallimore3042]

Hey man I’m an HVAC guy in Salt Lake City and I have to say I’m pretty impressed with your set up. I’m sure this is a yes but did you have your refrigerator & deep freeze running? It’s not a huge load just curious. Great video my man. Keep up the good work!

[@diyhvacguy]

Yes, I had two regular fridges (home and garage beer fridge) AND my deep freeze running 👍🏼

[@user-tk1ec1hd4e]

Just subscribed after watching this. I still cant pull off doing this alone so will just pay someone 🙈

[@marylandgal5286]

Thank you i rarely see vid about how to run hvacs on generators. Had never heard of a soft start kit! Can you run heat with this too? Or just AC ?

[@johnjames5842]

Only problem is in most states the natural gas is pumped using electrical powered pump stations, so no power in a wide area, and you may have no natural gas. The solution is a Tri-fuel generator, si you can use Nat gas, propane or gasoline, in freezing temps propane wont work, pressure is too low, you need heating blankets on the bottles . everything else in theis video is awesome and very helpful, im in the process of buying all the stuff to do this at our house, in case we have a weeks without power from a freeze or storm.

[@mfb6310]

So what are you going to do? I have NG but yes it is tied to the area's pump stations. If I chose propane, I'd have to get a big propane tank, the gen and wire it all, and keep it all warm. Huge battery bank is almost as expensive as a standing generator. I'm no electrician. Solar is too expensive to just decrease a monthly electric bill, if not in inclement weather by chance. And geothermal is expensive! Curious to your solution.

[@MadsWorld34]

wow its hard to believe that a generator that small would even run a house. i have a 8750 /7000 harbor freight and love it it runs my entire house. but it dont have a 50 amp plug. GRRR and i really like your power inlet box once in a while mine will work loose and i will lose have my house and thanks to you i just ordered one. even though it is only 30 amp. and the only gas we can get around here is propane so i more less have to stay with gas. another GRRR.

[@brentbrowning]

[@clivewarner2162]

Have a 5KW gen similar and it easily powers 2 mini splits, a 1.5Ton and a 2Ton.

Is there a solution for a well pump soft start to reduce the start pump Amp draw?

[@natestakely1478]

Neighbor just did this, he's now operating a portable AC in 100 degree temps in Louisiana while they look for a condenser fan motor.

[@CaptK-py8rq]

We were looking at this same generator at Costco. We have a single 5-ton AC unit, house is 3000 sf, will the soft start work with this generator with an AC this size? I know you said yours is only 2 tons. I was wanting to go this route since we have Nat-Gas. Last outage I used my gasoline only 7.5K generator. I wired in the 6 circuit Reliant transfer switch years ago but do not have the AC on it. Thank you and thank you for all of your informative videos!

[@boomni99y]

Do you have a video on how the transfer switch box was wired up ?

[@franksinatra2278]

You really should let the generator idle for a few minutes before drawing power. My owners manual makes a big point of that as it will extend the life of the generator.

[@jhariette]

I need a generator like this!!!!!

[@keiths1]

Could a similar set up be used for an emergency solar connection? Any recommendations for a generator that is a little more quiet? Or are there not many quiet options for generators that can handle all that power load?

[@aspitofmud6257]

Thank you. 👍

[@raulsanchez4493]

I need info on those soft start units & how to install them. I have 2 Goodman 2-ton units & I have a 10kw natural gas generator. I’m sure I can run both if I had those soft starts installed.

[@justinjones6810]

Just interested what brand of mini split do you think is the most reliable with the least amount of breakdowns

[@bubbatime]

Good video. Only thing I would do different is sell that generator and buy an inverter generator. Your generator has 15% total harmonic distortion which can and will destroy circuit boards in your house. Check out the Champion 201176 tri fuel inverter 9000 watt generator. It has less than 3% distortion

[@mikeperry2814]

I assume you turned off the dryer, stove and electric water heater (if applicable) breakers.

[@briananderson7030]

If I have a heat pump instead of an air conditioner do I still need that soft start if I want the similar set up? I live in Indiana so it is used for heating and cooling

[@philipmartin2622]

First, during many types of emergencies your natural gas will be shut off to prevent fires. Second, during an emergency your central air, electric stove, electric dryer and electric furnace use too much power and should not be turned on. If absolutely necessary, you can get a 5000-8000 btu window unit and only run it for a couple hours before bed time with the bedroom closed off and it should stay cool enough till morning. A microwave can do most of the cooking in just minutes on 1100 watts. You should be able to get by with a 3500 watt generator or inverter which will use far less fuel. While living off the grid, I have never found it necessary to run the generator more than a couple hours per day. Just 10 gallons of stabilized gas will easily last all week. A couple indoor/outdoor wireless thermometers keep track of the refrigerator and freezer to minimize run time. Always connect several items at once to more efficiently use your generator time. An oil lamp with a few quarts of lamp oil and some cheap solar yard lights($3each) can provide all your lighting. Using a smaller generator and being prepared for a long term power outage makes more sense than having something that powers everything but will run out of fuel in just a few days. I also use two heavy duty 50 foot extension cords and plug the appliances in directly to the generator rather than waste money on an expensive transfer box. Some people may have different needs but I don't want to waste money on a $10,000-12,000 whole house system just to use every convenience.

[@Johnnysokko168]

I have same setup but no gas in my area that would be so nice to have and not keep so many 5 gal cans around. I also have the suicide cord but i know what im doing i just back feed through garage panel. I am interested in the soft start for air thats the one thing i cant run on generator currently.

[@Ezekiel33USA]

I have this same setup, but I have a 2 ton and 5 ton AC units. I can run the 2 ton without soft start as long as I don’t have much else running on it. I am wondering if I could run a 5 ton with soft start.
