Do I pay for freight?
Freight is free from Generac to your loading dock or to our warehouse. From our warehouse stock, call for quote.
Is a battery included in my standby generator?
Natural gas/propane generators of 45kW and below are shipped without a battery, so you will need to supply it. Size: Group 26,CCA Cold Cranking Amps; 525 minimum. Example: AC Delco #2660 at 540CCA, or #2670 at 580CCA.
Is a battery included in my electric-start portable generator?
Portable generators are shipped without a battery, so you will need to supply it. See the spec sheet or manual. Most electric-start portables can also be started by a pull-cord recoil start.
Can my natural gas generator be converted to propane?
Since generators of 45kW and below are only shipped set up for natural gas, a simple field conversion will be required to use propane. For most models, in the regulator replace the natural gas orifice with the supplied propane orifice, and close the regulator about a quarter turn.
What does the "T" or "S" on a Towable generator's model number mean?
The Industrial Towable Generators whose MfrItem# ends with "T" includes the trailer; those ending in "S" are only on a skid.
What is NFPA? What's the difference between an NFPA generator and a non-NFPA one?
NFPA means National Fire Protection Association. The NFPA-110 standard applies to "Life Safety" applications.
An example of an easily-overlooked Life Safety application is Exit Signs that do not have an approved battery backup, nor a lighting-certified UPS backup, but rely solely on the Generator in case of an electricity outage. For other Life Safety applications, please consult the National Fire Protection Association.
So if you determine that you have a Life Safety application, please use our “QTA” Series, which is designed to meet NFPA-110. The price for all QT-NFPA generators includes the following standard equipment:
- 20-light Remote Annunciator Panel
- Brushless Exciter
- Block Heater
- H-100 Controller (H Panel with alarm relays)
- 10-Amp Battery Charger
- Sound-Attenuated Enclosure
- Startup Service Included
Do you have more generators that are not listed on this website?
Other generators are available in both this size range and up to 6 million watts. Please call us with your requirements.
How do I select which voltage and phase is appropriate for my generator?
Your electrician will tell you what voltage and phase is currently being supplied to your building. Normally you would use that voltage and phase, unless a reason exists to change the service (which can be expensive). These are the voltages and phases which we supply:
- 120/240Volt, single phase (written as 1ph)
- 120/208Volt, three phase (written as 3ph)
- 277/480Volt, three phase (written as 3ph)
- 120/240Volt, three phase (written as 3ph)
How do I know what size generator will meet my needs?
The size of the load (the power needed to run the appliances, lights, etc.) determines the size of the generator you will select. First, take inventory of all appliances and other uses of power in the building, recording the watts each requires to START and to RUN. (Starting wattage may be higher than running wattage, especially for motors, and you must allow for the starting wattage when the generator first starts up.) Then determine how many of these power-uses will be demanding power at any one time. The sum of all these wattages determines the minimum size generator you should choose. It is wise to allow some extra wattage in case your power needs grow in the future. For example, if you need 95,000 watts, you could either buy a 100kW or a 130kW generator.
What does "kW" mean?
"kW" stands for kilowatts, or thousands of watts. A 35kW generator will power 35 thousand watts, for example.
How do I choose between fuels, such as natural gas, propane vapor, diesel or gasoline?
- Is natural gas available at your site? If so, it may be the cleanest, most dependable source of fuel you can use. You will not have to refill a tank.
- If natural gas is not available, propane vapor is the next alternative to consider. The propane supplier should be able to answer your questions about availability in your area and how large a tank you should consider.
- Diesel fuel requires a tank also, which is sold with the generator. The generator may sit on top of the tank. Diesel fuel is more polluting than natural gas or propane vapor. Diesel supply in an power-outage could be a problem if the diesel supplier does not have power to refill his trucks.
- Gasoline should be the fuel of last resort because of the dangers associated with keeping it, and the possibility that it will degrade over time.
What are the advantages of aluminum enclosure VS. steel enclosure?
Aluminum does not rust. Steel inevitably rusts; Generac Power Systems' warranty for steel enclosures is one year.
What does 6.8L or 2.4L mean in the description of a generator?
The description of the generator contains the wattage, the engine size, the word "generator", the fuel, the enclosure, the voltage, and the electrical phase:
20 kW 1.6L Generator -- natural gas -- steel enclosure -- 120/208V 3ph
In this example, "1.6L" is the engine size.
Why does it say "switch only" on the description of some switches? What else would I get?
Some automatic transfer switches come bundled with a Service Entrance disconnect switch, or with cables. Other switches do not come with any extras; they are "switch only".
What does Tier 1, 2, and 3 mean?
Federal standards (Tier 1) for new off-road diesel engines were adopted in 1994 for engines above 37 kW (50 hp), to be phased in from 1996-2000.
Tier 2 standards were phased in from 2001-2006 and yet more stringent Tier 3 standards phase in from 2006-2008 (applying to engines from 37 - 560 kW).
Tier 4 standards, to be phased in from 2008-2015, further reduce CO and NMHC + NOx and PM emissions for engines from 37 kW - 560 kW.
