2025 Generac Mobile Stationary Generators
Ensure your business remains fully operational with the Generac SG1000. Designed to deliver 1,000 kW of standby power, this natural gas generator provides extended run times while meeting EPA certification for both emergency and non-emergency use. Built with Generac’s proprietary spark-ignited engine technology, the SG1000 is optimized for high-load acceptance and fast transient response, meeting NFPA 110 emergency power requirements. The SG1000 is engineered for reliability, efficiency, and ease of maintenance, offering cost-effective performance without compromising power output. With its durable enclosure options and advanced Power Zone™ Pro Sync Controller, this generator is a trusted solution for industrial and commercial applications. Generac has been a leading name in power generation for over five decades, designing and manufacturing diesel, natural gas, and bi-fuel generators that meet the demands of mission-critical applications across North America.
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 industrial alternators are machine wound, machine inserted, and machine varnished for the ultimate in consistency.
- Generac builds its spark-ignited engines from the block up utilizing advanced engineering expertise.
- The Generac Power Zone® Digital Control Platform is a fully integrated and multipurpose family of controllers for Generac’s single genset and Modular Power Systems (MPS) applications.
- 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.
