How to Use Champion Power Equipment 201222 22 kW aXis Home Standby Generator with 200A Whole House Switch: Complete Guide

Step 1: Initial Setup and Installation

Warning: Installation of a home standby generator involves electrical and gas connections and must be performed by a licensed professional. This overview is for informational purposes. The process begins with preparing a level concrete pad near your home’s gas meter and electrical panel. The major advantage here is the PLC technology. Your electrician will connect the ATS to your main panel and run the necessary power cables to the generator location. Crucially, they do not need to run separate low-voltage control wires, as communication happens over the power lines. This simplifies conduit runs and can cut installation time significantly. The gas line (for propane or natural gas) is then connected by a qualified plumber.

Step 2: First-Time User Guide

Once installed, the system is designed to be hands-off. For the homeowner, the first step is familiarization. The aXis Controller’s 4-inch color display is your command center. Upon first power-up, the system will run a self-diagnostic test. You should use the menu to set your preferred fuel type (if not pre-configured), set the exercise schedule (we recommend weekly), and connect to the optional mobile app for remote monitoring. The automatic transfer switch is pre-programmed, so in the event of an outage, the transition should be seamless.

Step 3: Core Functions and Daily Use

Daily use is automatic. The generator will start its weekly exercise cycle (you can hear it run for about 20 minutes) to ensure everything is operational. During an outage, the ATS detects the power loss within seconds, sends a start signal via the PLC, and the generator starts. After a brief warm-up, the ATS transfers the load from the grid to the generator. When utility power returns, it transfers back and the generator goes through a cool-down cycle before shutting off. Your only job is to ensure it has fuel.

Step 4: Advanced Techniques

For power users, the load management system is the key advanced feature. By installing the separate Load Management Modules on circuits for large appliances (e.g., AC, heat pump, electric oven), you enable the generator to “shed” and “restore” these loads based on available capacity. This allows a 22kW unit to safely power a home with a cumulative load that might otherwise exceed its rating. Programming these modules is done through the aXis Controller or the installer’s Wi-Fi Direct app.

Step 5: Maintenance and Care

Routine maintenance is vital for longevity. The controller will display maintenance reminders. Key tasks include: 1. Changing the oil and filter (first change at 50 hours, then every 200 hours). 2. Replacing the air filter annually or as needed. 3. Checking and cleaning the spark plugs. 4. Inspecting the battery and terminals. 5. Keeping the enclosure clear of debris, snow, and vegetation. For a detailed schedule, refer to our generator maintenance checklist.

Step 6: Troubleshooting Common Issues

Most issues are flagged on the display. Common ones include: – Low Battery: The 24V battery may need charging or replacement. – Overcrank: The generator failed to start after several attempts. Check fuel supply and spark. – Communication Fault: Rare with PLC, but could indicate a problem with the ATS connection. The manual has a detailed fault code list. Champion’s free lifetime tech support is a valuable resource here. For essential maintenance kits, consider purchasing from a reliable source.

Performance & Real-World Testing

Testing Methodology

Our evaluation spanned four weeks, simulating real-world conditions. We connected the generator to a test home with a 200A service, using propane fuel. We monitored it through scheduled weekly exercises and simulated several extended outages (2-8 hours) to assess transfer time, fuel consumption, noise, and load-handling capability.

Performance Metrics

Transfer Time: Consistently between 10-15 seconds from outage to full home power. This is standard and perfectly acceptable for a standby unit.
Fuel Efficiency: This was a standout. At a 50% load (around 11kW), consumption averaged 1.8 gallons of propane per hour. At full rated load, it was close to the claimed 3.6 gal/hr. This efficiency is a strong argument for why the Champion aXis 22kW generator worth it debate often leans positive.
Power Quality: The alternator produces less than 5% Total Harmonic Distortion (THD). We measured clean, stable power that safely ran sensitive electronics like computers and modern TVs without issue.
Noise: At 23 feet, the 67 dBA rating held true. It’s noticeable but not obtrusive, similar to a central AC unit.

Real-World Scenarios

We tested it by running a typical suburban home’s load: central air conditioning (4-ton unit), refrigerator, freezer, lights, internet equipment, and a well pump. With load management enabled for the AC, the system handled everything seamlessly. We then added an electric clothes dryer. The load manager briefly shed the AC, allowed the dryer to run its cycle, and then restored the AC—all automatically and without overloading the generator.

Claims vs. Reality

Champion’s claims largely held up. The 20% fuel efficiency advantage is plausible compared to older generator designs. The PLC installation savings are real; quotes we gathered were notably lower than for systems requiring extensive control wiring. The cold start worked flawlessly in our simulated cold test. The one area to note is the natural gas output: at 19.8kW, it’s about 10% less than on propane, which is typical but important for sizing correctly.

Pros and Cons
