DISCOUNT ELECTRIC GENERATORS

PORTABLE AND STANDBY MODELS IN THE POWER RANGE 1,000-17,000 WATTS

There are two main types of generators (gensets) for home use: standby and portable.
Standby generators are hardwired to the house electrical system via a transfer switch and permanently connected to an external fuel source (such as LPG or natural gas). They can provide continuous power in case of emergency for as long as the fuel is available (see standby models review and ratings).
A portable generator is normally used for temporary powering selected AC loads via extension cords or via a cable plugged to a manual transfer switch. This type is generally cheaper than stationary, but most models get the fuel from an on-board tank and therefore need frequent refueling. Some multi-fuel portables, such as NorthStar 8000 TFG listed below can also be connected to an external fuel source for extended runtime (see portable models review and ratings).
Prices for residential gensets range from about $100 per kW to as much as $1000/kW. Here you will find info on some of the popular models at discount prices, which we picked in various genset categories.

NOTES:

The "best prices" shown above relate to what you can get from Amazon.com site. In most cases they represent a discount from the respective manufacturer's list prices or MSRP. It does not imply that other retailers are selling at MSRP, but these prices often are indeed the lowest ones you can find anywhere online at authorized dealers. However, you should always do your own research. Prices do not include taxes and shipping, although Amazon usually offers free shipping on their gensets.

An average size single-family house typically needs 4 to 7 kW to power essential items. Among midsize portables, Eastern Tools and Blue Max series feature one of the lowest cost on the market. For California emission regulations consider CARB compliant PowerMax series with included wheel kit. For a jobsite or camping trips Blue Max's Contractor Line is probably the cheapest in its class.

The homes with up to 4-5 ton central air conditioner would normally need a 14-17kW system (see our sizing guide). In this power range, GUARDIAN® models have probably the lowest dollars per kW among top brands. Note you can order installation and service of your GUARDIAN® or Generac system from their local dealer regardless of where you bought it. Note that while standby models are usually listed by their continuous power, portable models are usually advertised by their peak (start) power.
