2025 Generac Mobile Stationary Generators SG150-9-0
As electrical grid outages become more common it is important to be prepared for the potential of a power outage. Keep all your business’s essentials up and running with Generac's 9.0L 150kW generator. Our rugged natural gas generators give you all the backup power you need until grid power is restored. All of our industrial gas generators are completely cost effective and give you the best value for the output so you can afford more of what you need for your business. Generac is one of North America’s largest suppliers of power generation equipment. For more than five decades, Generac has designed and manufactured diesel, natural gas, and bi-fuel generators that meet the demands of any application.
Features may include:
Generator Enclosure- Generac manufactures its own enclosures, ensuring each unit combines the highest level of durability, noise reduction, weather resistance, and streamlined design.
- Generac builds its spark-ignited engines from the block up utilizing advanced engineering expertise.
- Generac industrial alternators are machine wound, machine inserted, and machine varnished for the ultimate in consistency.
- Generac engineers its generator controls with safety and convenience as top priorities.
- Generac's Modular Power Systems (MPS) boast a rate of up to 99.999% reliability, and are more cost-effective and flexible than single generators with the same load capacity.
