(Generac Commercial): 80 kW Generator Sets LP Aluminum 1-Ph

…Single-Phase Volts; Propane Operation

This standby generator is best suited for: 1)restaurant or food retailer of dimensions 2500 to 3000 square feet (applies to any business dealing in perishables; must require 1-phase power); 2)commercial warehouse or non-food retailer of dimensions 9000 to 10000 square feet (includes all business enterprises that don't handle perishables); model can also be used to back up: 3)a residential complex that operates on 1-phase power (application with multiple or separate buildings needing backup); 4)extra-large homes 15000 to 20000 or so square feet (if this much backup capacity needed; even large applications can usually get by with less).

The 1-phase Commercial-series 80 kW generator sets standby is a fine choice for your business application, but, if necessary, it can provide reliable long-term backup in large residential settings. Be cautious, when considering a generator sets model of this size for residence, that capacity really needed. This will prevent generator from operating for long stretches at low output (not recommended for any generator type or size). This liquid-propane burning generator sets unit possesses Generac's rust-proof aluminum housing, especially good for high-humidity or coastal areas. Has 4.6 liter V-8 engine, and brushless alternator (digitally regulated to +/-1.4%); controller for 80 kW generator sets model is Nexus series with tri-lingual capabilities. When selecting transfer equipment for generator sets combination, our recommendation is one of Generac's own single-phase RTSX switches (see Switch Options tab for available automatic RTSX models). These switches were designed for compatibility with Nexus controller, and should make implementation of the unit easier. Is good idea for companies seeking generator power to have requirements assessed by an electrician before model purchased. This generator sets standby is not for sale to California or Massachusetts residents

    The T-REX Free Shipping Pledge:
    The manufacturers we work with are large concerns that ship multiple items each day. This enables them to attain the best shipping rates available. T-REX passes these savings on to our customers by providing free shipping to any commercial or residential address in the continental United States. This is the T-REX pledge. We will adhere to it even when a freight carrier adds one-time or unanticipated shipping fees. Try obtaining these terms from another Internet-based generator seller. You will not find a more customer-friendly policy than ours.

    About Lift Gates:
    Typical delivery trucks are designed to be unloaded at docks, or by forklifts. In other words, they are designed to deliver to commercial locations where such options are available. By contrast, a lift gate-equipped truck lowers heavy items from the truck trailer (which can be several feet high) to the ground, using a hydraulic mechanism similar to an elevator. If your delivery will go to an address not equipped with a loading dock, and you don't have access to a forklift, then selecting the lift-gate delivery option is a convenient alternative.

    A generator from T-REX can weigh hundreds of pounds. Without access to a loading dock or forklift, unloading one safely may require several able-bodied individuals. Delivery drivers are NOT required by their companies to help customers unload. Unless you are certain that a sufficient number of helpers will be available during the delivery, we urge you to specify the lift-gate shipping option before checking out. Charge for the lift-gate is $75.00, and is NOT included in the Free-Shipping Pledge offered by T-REX. We feel, however, that it is worth the investment.

    Residential Delivery:
    You need to inform us if your delivery will be going to a residential address. Freight companies need to know this because many residential areas can't be serviced by large semi trucks. The generator will instead be loaded onto a smaller truck tailored to home deliveries. A home which serves as a place of business (regardless of the presence of company name/signage), if located in a residential area, is still considered a residential address for shipping purposes. Please select the residential delivery option if applicable. T-REX agrees to pay all additional residential delivery costs, but to do so, we must be properly informed before shipping arrangements are made.

    To select your choice of residential or commercial delivery, please see the purchase options in the Add To Cart area.
