Buying a diesel generator
What Florida buyers need to know.
Choosing a diesel generator starts with the equipment, building, or property that needs power. The correct generator depends on the electrical load, voltage, phase, starting requirements, expected run time, and whether the unit will provide standby or regular power.
You do not need to work through those details alone. GTG Power brings 30 years of generator repair and sales experience to each conversation. We ask practical questions, explain suitable options, confirm current availability and price, and arrange delivery to your Florida location.
New to this? Start with how generator sizing works, or see what each kW range typically powers. If this is for storm season, read planning hurricane backup power.
Want new equipment instead? We supply new generators from 10 kW to 600 kW, built to order, with the full specs and what each size runs.
Shopping by manufacturer? Compare the major diesel generator brands — Cummins, Caterpillar, John Deere, Kohler, Generac, and Detroit Diesel. If the unit needs an air permit, read about EPA emissions tiers first.

Common questions about buying a diesel generator
Do I need to know the generator size before I call?
No. Tell us what needs power and we will help identify the information needed to choose an appropriate size. Most customers do not arrive knowing their load, and that is normal.
Where can a generator be delivered?
Delivery can be arranged to homes, warehouses, businesses, farms, and jobsites throughout Florida, in all 67 counties.
What affects the price of a diesel generator?
Size, configuration, equipment condition and hours, current availability, transportation distance, site access, and unloading requirements all affect the final quote.
Are used industrial generators reliable?
Industrial diesel gensets are built for long service lives, and low-hour units regularly come out of facilities that upgraded or closed. What matters is verified hours, maintenance history, test results, and the real condition of the engine, alternator, and controls. We confirm those on the specific unit before you buy.
Do you sell trailer-mounted generators?
Yes. Trailer-mounted units suit jobsites, farms, events, and any situation where the generator has to move or where a permanent installation is not practical.
What is the difference between standby and prime rated generators?
A standby rating assumes emergency use with limited hours per year. A prime rating assumes the generator is the main power source running unlimited hours at a varying load. The same unit carries a lower prime rating than its standby rating, so tell us early which one applies to you.
