      The Generac 7226 Guardian Series 18 kW Standby Generator delivers powerful whole‑home backup protection with advanced monitoring features, durable construction, and the proven reliability of Generac’s G‑Force air‑cooled gas engine. Designed for fully automatic operation, the 7226 restores power within seconds of an outage, keeping essential systems—HVAC, refrigeration, lighting, well pumps, and electronics—running smoothly and without interruption.

      The heavy‑duty G‑Force engine is engineered for long‑term performance with reduced maintenance requirements and consistent output under varying load conditions. True Power™ Technology provides clean, stable power with low total harmonic distortion, making it safe for sensitive electronics and modern appliances. Quiet‑Test™ self‑test mode allows the generator to run weekly at a lower RPM, reducing noise and fuel consumption while verifying system readiness.

      Built for year‑round outdoor installation, the 7226 features a corrosion‑resistant aluminum enclosure and weather‑sealed design to withstand harsh environments. Flexible fuel compatibility—operating on natural gas or liquid propane—supports a wide range of residential installations and ensures dependable performance during extended outages.

      Integrated Mobile Link™ Wi‑Fi connectivity allows homeowners to monitor generator status, maintenance alerts, and operating conditions from any smartphone or connected device, providing real‑time visibility and peace of mind.

      Ideal for mid‑size to larger homes seeking robust, automatic backup power, the Generac 7226 Guardian Series combines strong 18 kW performance, smart monitoring, and long‑lasting durability to keep homes protected when utility power fails.
