Generac Spark-Ignited Engines: Engineered for Standby Power
Applying gaseous fuel to standby power systems takes advanced engineering expertise to ensure reliability and long life. That’s why Generac builds its spark-ignited engines from the block up. Adding the fuel system. Hardening the valves and seats. Adjusting engine timing. This allows Generac engines to last longer, require less maintenance, and perform more reliably in a standby power system than a third-party spark-ignited engine. And each Generac engine meets the required EPA emission standards at the factory.
PowerManager®
Reliable, Accurate, Integrated Controls Generac engineers its generator controls with safety and convenience as top priorities. PowerManager® digital controls let you monitor and control key elements of your generator system with the touch of a button or click of a mouse. In addition, features like constant monitoring capabilities, adjustable parameters and built-in protective alarms combine with seamlessly integrated components for the highest level of reliability
Protection from the Elements
By manufacturing our own generator enclosures, Generac is able to ensure each unit combines the highest level of durability with the latest engineering advancements in noise reduction, weather resistance and streamlined design.
Optimized for Performance
Generac industrial alternators are machine wound, machine inserted, and machine varnished for the ultimate in consistency. Form winding and stack bracing ensures reliable performance. Rotor spin balancing eliminates vibration. And vented rotors contribute to cooler operation, longer life and enhanced efficiency.
