Natural Gas Generators for Sale

Natural gas ratings

Most standby generators produce less power on natural gas than on propane. Check the natural gas rating, and have a plumber confirm your gas meter and line can supply the unit at full load.

Buy online with clear pricing

Every listing shows the selling price, stock status, fuel type and whether a transfer switch is included, so you can compare and buy in minutes. Use Buy Now on any product to start your order — no quote requests, no waiting for a callback.

What to check before you order

Confirm the kW rating for your fuel, your electrical service size (for example 200A), the transfer switch you need, and where the unit will be placed. Freight-shipped equipment needs someone available to receive the delivery.

Ready to buy?

Pick the generator that fits your home or business, check the price and what's included, and place your order online. If you're not sure which size to buy, start with the kW rating pages or contact us before you order.

Is installation included?

No. Unless a listing says otherwise, prices cover equipment only. Standby generators should be installed by a licensed electrician and, for gas connections, a qualified plumber, following local permit rules.

How are standby generators delivered?

Standby and commercial generators ship by freight on a pallet. Confirm curbside delivery terms and that someone can receive the shipment before ordering.
