Generac 150kW Protector Standby Generator
One-fifty kilowatts. The biggest we stock.
Natural gas or propane, catalyst-equipped, single-phase or three-phase at 208, 240, or 480 volts. Industrial, data and telecom, multi-building sites. On propane it delivers 120.
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 generatorsWhat a 150kW runs. Buildings, not houses.
Three-phase commercial and light industrial loads: refrigeration, rooftop HVAC, pumps, kitchens, offices. Sized from a load study, not a square-footage table.
- Walk-in coolers and freezers
- Rooftop HVAC and make-up air
- Lift-station, well and fire pumps
- Commercial kitchens and registers
- Server rooms, security, egress lighting
Typical commercial loads. A load study on site decides the size. Request a free site visit and we measure what has to stay on.
For the site where the outage is the emergency.
Servers, switches, production lines. One-fifty on natural gas, in stock in the Houston area, which after a storm is the difference between next week and next quarter.
Data and telecom, production, multi-building.
Servers, HVAC, production equipment, lighting, offices.
Senses the outage, starts itself, switches the building over. Hands it back when CenterPoint returns.
- Pick it if: the load runs to 150 and you need it in stock, not on order.
- Past this: we'll spec it with Generac Industrial and quote it. Call.
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 keeps the doors open.
Sized for the whole building, not a few circuits. Coolers, HVAC, registers, lights, and the servers, all at once.
Natural gas or propane, not diesel.
No fuel deliveries during a storm, no tank to keep topped, no stale fuel. It runs off the gas service you already have.
In the phase and voltage you already have.
120/240 volts single-phase, or 208, 240 or 480 volts three-phase. We look at your service and match it.
Clean enough for anywhere.
Catalyst-equipped and EPA certified for standby use, so it goes in where emissions rules are strict.
Sound-attenuated.
Built to sit next to a building full of people without being the loudest thing on the block.
We service it after.
Scheduled maintenance, load testing, and a crew that already knows your building when something does go wrong.
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.
For the people who want them.
Everything below is from Generac. Ask us if any of it needs explaining. That's what we're for.

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.
