Generac 30kW Protector Standby Generator
Thirty kilowatts, liquid-cooled.
Estates, small restaurants, dental offices. Runs cooler and quieter, built for the long haul. When the outage is three days, this is the engine you want out there.
Financing through Synchrony and others. How that works →


Generac Prestige DealerGenerac's highest dealer designation. We sell, install and service Generac home standby generators.
Generac generators$2,000 off a generator install. While supplies last.
It only comes off the units on our floor, so when they're gone, it's gone. New air-cooled Generac installs come with a free 10-year warranty, and financing is there if you want it. Permit timing depends on your city or county. The install itself is usually one day.
What a 30kW runs. Big houses, three ACs, 400-amp service.
Liquid-cooled power for the biggest houses and small businesses: three or more air conditioners, a pool, an outdoor kitchen, two panels.
- Three central AC units
- Two electrical panels on 400-amp service
- Pool pump, heater, outdoor kitchen
- Electric range, dryer, water heater
- Well pump, gates, EV charger, guest house
These are typical loads for this size with gas appliances and Houston-size air conditioning. Your panel, your AC tonnage and what you want on during an outage decide it. Five taps on the calculator gets you a recommended size; the free sizing visit makes it exact.
For the estate, the restaurant, the practice.
A big load and a long outage. The 30 runs cool, quiet, and all week if it has to.
Or a restaurant, clinic, or dental office.
Multiple ACs, walk-in coolers, well pumps, the kitchen line. Nothing turns off.
Senses the outage, starts itself, switches the house over. Hands it back when CenterPoint returns.
- Pick it if: a large home with a lot of AC, or a small business where a dark day is a lost day.
- Step up if: elevators, a big well pump, or a building on three-phase service. Look at the 32 or the 40.
Not sure? Five taps on the calculator gets you a size, or call and we'll size it on the phone.
In plain English.
Generac's spec sheet has a lot of words on it. This is what they mean for you.
It turns itself on.
Power goes out, it senses it, starts, and switches everything over in about ten seconds. Power comes back, it hands it back. Nobody has to be there.
A car-style engine, built to run for days.
Liquid-cooled, like the engine in your truck. It runs cooler, quieter, and longer than an air-cooled unit, which is why this is what goes in when the load is big or the outage might be long.
Quieter than the size suggests.
A sound-attenuated enclosure and a slower-turning engine. Neighbors, patients, and diners notice less than you'd think.
It runs on natural gas or propane.
The gas line you already have, or a tank. No diesel deliveries, no fuel going stale.
Single-phase or three-phase.
We match the unit to the service your building already has. You don't need to know which. We look at the meter.
You can watch it from your phone.
Mobile Link app. Cellular built in with Wi-Fi backup. Status, run history, and service alerts from anywhere, and the servicing dealer can see faults early.
Wired installs, around Houston.
Real photos of our installs around Houston and Tomball: the unit set on its pad, the transfer switch and gas line run, and the startup test before we leave. The unit in a photo may be a different size than this one.

No price tag on the website. Here's why, and how to get your number.
The unit is only part of it. The gas run, the pad, the transfer switch, and your panel change the number from one house to the next, so a price on a web page would be wrong for most people. Getting the real one is quick.
