Generac 7259 18kw Next Generation Air-Cooled Standby Generator - Includes Cellular, Wi-Fi & Bluetooth Connectivity

The Generac 7259 is a powerful and efficient 18kW home standby generator, purpose-built to deliver continuous backup power to homes during outages. Equipped with advanced technology, a rugged engine, and remote monitoring capabilities, this air-cooled model is ideal for protecting whole-home systems or heavy-duty essential circuits-keeping your appliances, HVAC, and electronics running without interruption.

At the heart of the 7259 is the Generac G-Force 800 Series engine, a durable 817cc, 2-cylinder OHV engine specifically engineered for demanding standby use. Running at 3600 RPM, this engine features hydraulic lifters, a full-pressure lubrication system, and cast iron cylinder sleeves, allowing it to operate longer with minimal maintenance and superior performance-even in extreme conditions.

The generator produces 18kW on propane and 17kW on natural gas, maintaining excellent power output across fuel types without compromising efficiency. With True Power™ Technology, the 7259 delivers clean, utility-grade electricity with <5% total harmonic distortion (THD)-safe for modern electronics, home automation systems, and variable-speed HVAC equipment.

Smart management is handled by the integrated Power Zone™ 200 controller, a digital display that provides system status, maintenance alerts, exercise scheduling, and diagnostics. The 7259 also comes standard with Wi-Fi, Bluetooth, and Mobile Link™ connectivity, allowing homeowners to monitor and manage their generator remotely through a smartphone or computer, receive real-time notifications, and track fuel usage or battery health.

The unit’s Smart Exercise Mode allows the generator to skip its weekly self-test if it has already run in the last 72 hours-saving on fuel and reducing wear. When it does run, Quiet-Test™ mode lowers the engine speed, reducing the sound level to an impressively low 55 dB(A). At full load, the generator operates at just 65 dB(A).

Protected by a durable aluminum enclosure, the 7259 is wind-rated to 150 mph, finished in Generac’s corrosion-resistant Metro Gray powder coating, and approved for placement as close as 18 inches from a structure (per code). Routine maintenance is streamlined with easy-access panels and integrated LED service reminders.

Fuel consumption is highly efficient for its class, using approximately 235 ft³/hr of natural gas or 105 ft³/hr (2.87 gal/hr) of propane at full load. It also includes key safety features like low oil pressure shutdown, oil level sensor, and emergency shutdown button.
