In-Depth Feature Highlights
Unmatched Power Output
This generator delivers 20,000 running watts and manages surges up to 28,000 peak watts, providing ample capacity to power central air conditioning, electric heaters, refrigerators, sump pumps, and high-load equipment without compromise.
Heavy-Duty Engine & Fuel Endurance
At its core sits a 999 cc V‑Twin OHV engine with a cast-iron sleeve design, known for durability and heat resistance. The generous fuel tank (approximately 17 gallons) grants up to 11 hours of runtime at 50% load, providing extended support during prolonged outages.
Modern Starting Convenience
Starting is streamlined via a push-button electric start combined with a remote key fob, enabling activation without manual intervention and adding ease in emergency situations.
Safe and Clean Electrical Output
Total Harmonic Distortion stays under 5%, delivering clean sine-wave power safe for sensitive electronics like computers, medical devices, and modern appliances.
Outlets Galore
The control panel includes an array of covered outlets: four 120 V GFCI duplexes, one 120 V 30 A twist-lock, two 120 / 240 V 30 A outlets, and two 120 / 240 V 50 A outlets—making it well-suited for everything from household circuits to wholesale load panels and transfer switch integration.
Essential Safety Mechanisms
The inbuilt carbon monoxide sensor automatically shuts down operation when dangerous levels are detected—augmenting user safety. Additionally, low-oil shutdown, overload protection, and a fuel gauge enhance operational safety and usability.
Built for Mobility Despite Size
Though heavy, it’s made portable through solid wheels, reinforced handles, and lift brackets housed within a steel frame—facilitating movement over moderate terrain.
Smart Monitoring
A built-in VFT data display reports voltage, frequency, and cumulative run hours. The smart idle control reduces engine speed under light loads, conserving fuel and minimizing noise.
Coverage and Support
The unit is supported by a 3-year limited warranty covering service, labor, and parts, and backed by lifetime technical support from Westinghouse’s service network.

4. Transfer Switch Compatibility
Compatible with transfer switches, it can safely connect to your home’s circuit panel, allowing direct power flow to essential systems.
Routine Maintenance Tips
To maintain the long-term health and performance of your portable generator, consider the following:
- Change Oil Regularly: Follow the manufacturer’s schedule. Typically, after the first 20 hours, then every 100 hours or annually.
- Check and Replace Air Filters: Clogged air filters can restrict engine airflow and reduce power efficiency.
- Run the Generator Monthly: Even if unused, a 15-minute run under load each month keeps fuel systems lubricated and battery charged.
- Inspect Spark Plugs: Look for carbon build-up or wear. Replace annually or as needed.
- Store with Stabilizer: Use a fuel stabilizer during long-term storage to prevent gasoline from breaking down and gumming up the fuel system.
Safe Operating Guidelines
- Never Run Indoors: Use the generator outdoors only, well away from windows, doors, and vents.
- Keep Dry: Operate under a canopy or weatherproof cover if needed.
- Proper Load Management: Always connect high-load appliances first, followed by lower-wattage items.
- Use Heavy-Duty Extension Cords: Use generator-rated cords with appropriate wattage and grounded outlets.
