Generac 7259 Air-cooled Standby Generator 18kw 17kw

Product Description

The GENERAC 7259 is a next-generation air-cooled standby generator designed for automatic backup power in residential applications. It delivers 18 kW on LP gas and 17 kW on natural gas, driven by an Electronic Fuel and Ignition Control (EFIC) system that manages fuel delivery and spark timing electronically. The EFIC architecture supports improved fuel economy and reduced emissions compared to carbureted designs. An advanced onboard controller handles system monitoring, and integrated cellular connectivity allows remote access and diagnostics. Licensed electricians and generator technicians are the primary installers.

The GENERAC 7259 is suited for whole-home or critical-load standby service in residential settings. It operates on natural gas or LP gas, making it adaptable to a wide range of utility and propane supply configurations. The integrated cellular module supports remote diagnostics without requiring a separate communication device, which reduces service call frequency and supports extended maintenance intervals. This unit is appropriate for new installations and for replacing aging air-cooled standby generators where a higher-output, lower-emission unit is required.

Key Features

• EFIC system provides electronic fuel and ignition control for consistent output and fuel efficiency
• 18 kW output on LP gas, 17 kW on natural gas
• Integrated cellular connectivity for remote monitoring and diagnostics without add-on hardware
• Advanced controller with enhanced system monitoring and status reporting
• Extended service intervals designed to reduce total cost of ownership
• Air-cooled design eliminates the maintenance requirements associated with liquid-cooled systems

Compatibility

Designed as an OEM air-cooled standby generator for residential natural gas and LP gas standby power systems. No specific compatible transfer switch or load center model numbers were provided in the product data.

Installation Notes

Installation must be performed by a licensed electrician and, where required, a licensed gas fitter or plumber for the fuel connection. Local building permits and inspections are typically required, and installation must comply with NEC Article 702 for optional standby systems and applicable fuel-gas codes. Disconnect all power sources and shut off the gas supply before servicing the unit. Do not operate the generator in an enclosed space; follow manufacturer clearance requirements for all sides and the exhaust outlet.
