Generac 18kW Home Standby Generator with 200A Automatic Transfer Switch
The Generac 18kW Home Standby Generator provides reliable automatic backup power to help keep your home running during unexpected power outages. Designed to connect to an existing liquid propane (LP) or natural gas supply, the generator automatically detects a utility power interruption and starts within seconds, then shuts down when utility power is restored.
With dual-fuel capability, an included 200-amp automatic transfer switch, advanced controls, and a weather-resistant aluminum enclosure, this standby generator is designed for dependable whole-home or essential-circuit backup power.
Key Features
- Dual-Fuel Capability – Operates on either liquid propane (18kW) or natural gas (17kW), providing flexible fuel options.
- 200A Automatic Transfer Switch – Automatically transfers the home’s electrical load to generator power when an outage occurs and returns to utility power when service is restored.
- True Power Technology – Produces clean, stable power with less than 5% total harmonic distortion, suitable for sensitive electronics and household appliances.
- Power Zone 200 Controller – Features a user-friendly LCD interface, system diagnostics, multilingual display, and wireless connectivity through Wi-Fi and Bluetooth.
- Quiet-Test Mode – Runs the generator at a reduced engine speed during scheduled self-tests to help minimize operating noise.
- Smart Exercise Technology – Helps optimize routine generator testing, fuel consumption, and engine wear.
- Weather-Resistant Aluminum Enclosure – Durable, corrosion-resistant housing designed to withstand demanding outdoor conditions and wind speeds up to 150 mph.
- Compact Installation Footprint – Can be installed as close as 18 inches from a structure where permitted by applicable local codes.
- Efficient Fuel Consumption – Uses approximately 2.87 gallons per hour of LP or 235 ft³ per hour of natural gas at full load.
Automatic Backup Power
The generator continuously monitors utility power and automatically starts when an outage is detected. Once utility service returns, the system transfers the electrical load back to the utility and shuts down automatically.
Advanced Monitoring and Controls
The Power Zone 200 controller provides convenient access to system information, diagnostics, and operating controls. Wi-Fi and Bluetooth connectivity allow users to monitor generator status and system information remotely.
Durable Outdoor Construction
The weather-resistant aluminum enclosure provides protection against outdoor elements while helping resist corrosion. Its compact design allows flexible placement around the home when installation requirements and local codes permit.
