Default Generators

In the process of building a house and I am putting in a generator. I have seen plenty of stuff on Generac and seems like a lot of people have them. Looking to do the whole house so possibly a 10k. I then was told about Briggs and Stratton and they are also good. Looking for some feed. Ack on both. They will be powered by natural gas. Thank you in advance,

Mark

Spend a lot of time researching this.

First 10k probably won't do a whole house.

Lot of variables involved. Air cooled vs water cooled, 3600rpm vs 1800rpm, propane, ng, diesel.

Generac is a minimum starting point on average and now builds most of their units.

B/S are mostly big box store minimal units.

the lifespan of the air cooled generac is measured in hundreds of hours wheras water cooled units, which run much cooler run in boats for thousands of hours. In an area like so .Fl where it is rarely used it is good for years. Up north where it is used frequently, a water cooled unit such as Kohler,Onan,Cummins etc is a multi-;year investment.
Unless you have a 2000 sq foot house the 10k won't power all of it. However you could prioritize which appliances you need in an emergency and get by.

Questions: What fuel /type of central heating do you have
What size air conditioning
What fuel/type of hot water heater do you have
Electric or gas stove/oven?
Well /septic or sewer and city water?

If your house is gas heat, gas stove, gas hot water heater, city water and sewer, then 10k may be able to run everything.

If you have electric hot water, electric stove, well pump, septic pump (if applicable) then 10k is to small.

The air cooled 3600 rpm generators are great for cheapness and infrequent use. However their efficiency sucks. 1800 RPM water cooled sets are significantly better in every aspect. From voltage regulation to fuel consumption, noise, etc. They are also a lot more expensive. Then you have to chose diesel or propane. Its nice to have 1k plus gallons of propane that you can store forever, but you can't just go get more if you run out . Diesel you can't store are many gallons with out treatment, but you can get a diesel transfer tank and move 75-100 gallons yourself at a time.

Kohler and Cummins/Onan tend to use proprietary controllers and regulators especially on smaller sets. Other smaller companies use generic commercial parts that are much more readily available. You don't have to go name brand if you're going 1800 rpm conventional alternator sets. Don't let a small packager scare you. Companies like State line, tradewinds, or Gillette generators, there are many out there.

Do a search here, there are MANY genset manufactures. http://www.egsa.org/Membership/Membe...orySearch.aspx

You have to have a good servicing dealer for whatever brand you have. Generac and Kohler probably your best bet.

This is true if you are going Generac, briggs ect.
Once you step up a level in sets they start to use cookie cutter parts.
Any good generator service center should be able to trouble shoot an AVR no matter what brand, or a bad winding in a marathon or meccalte alternator (no, not the 12V type, the alternator is what actually generates the power).

In fact, it is sometimes easier to trouble shoot and service off brand sets. They still use Deere, kubota, etc for engines. Baseler, Deep Sea, Comap, or Datakom for the controller. Governeros america for the AVR and or governor if equipped.

We have been in the generator industry for 26 years selling to all of the packagers. I have a store room full of AVR's, controllers, chargers. I have a 25KW kohler set and I had to order a specialty kohler part for 600 dollars to fix my set. Or it would have been a part I sell for 75 dollars if it was any other manufacturer. I don't like proprietary parts in generators.

Of course if you only want to spend 3k then pick whatever brand the big box store has.

I had Tradewinds build me a John Deere/Marathon 60kw diesel whole house unit.

You can treat the fuel for 10-15+ years. I have 2 medium tanks vs one large tank and rotate fuel out.

Whole house, constant duty rated, fuel efficient (propane units will kill your wallet, if available), quiet (noise is a big deal), off shelf parts, aluminum housing/stainless steel hardware, serviceable by any technician.

New construction saves $$.

Adds value to your house.

My father has a 10k generac. I think he paid $2500 for the unit. It held up during Sandy, he was just lucky his neighbor is friends with the propane dealer and got topped off the third day without power.

Burn rare is about 1-1.2gal/hour of propane.

As mentioned above it most likely will not power your central AC. My father is 100% electric single unit heat pump so unless he went way larger not going to work. He has had the unit for 5 years and no significant issues. Turns on every week for 10min to test.

One issue it's loud as F$?€. Unless you want to drop double or more they aren't bad units.
