Dual Fuel Benefits

This portable generator can run on gasoline or propane, allowing you to use whichever one is more accessible.

Propane is a far cleaner fuel than gasoline and has multiple significant benefits. Propane is, without a doubt, a much cleaner fuel source than gasoline. Because it contains fewer impurities and generates fewer by-products during combustion, propane reduces harmful emissions considerably. This makes it safer for the environment.

Propane generators are less vulnerable to the problems caused by cold weather, which can hurt the performance and reliability of gasoline units. Propane also has an indefinitely long shelf life, unlike gasoline, which requires further storage additives and does not last more than a year or two. As a result, long-term supply is much easier with propane.

For anybody who wants the security of having a more versatile backup power supply, dual fuel propane generators are an excellent choice. Click the following link to see more about the pros and cons of propane vs. gas generators.

Why use an inverter generator?

Every generator, regardless of type, produces electricity. However, inverter generators generate AC power and then convert it to DC and back to AC. This method ensures a more stable power flow, which is especially important for properly operating many electronics. This also allows the generator to operate more efficiently under common power usage conditions. And inverter generators are frequently quieter than standard portable generators.

FAQ

How can I maximize fuel efficiency with my DuroMax XP9000iH?

To get the most runtime per gallon, run only what you need—avoid powering unnecessary appliances.

Use propane for longer shelf life and cleaner operation, but gasoline may offer slightly higher peak output.

Keep the generator’s air filter and spark plug clean, and operate in ECO mode when possible to reduce fuel consumption.

What should I do if my XP9000iH won’t start or keeps shutting off?

First, check the basics: ensure there’s enough fuel, the oil level is correct, and the battery is charged. If it still won’t start, inspect the spark plug and air filter for dirt or damage. For shutdowns, check for tripped breakers, CO sensor activation, or low oil. If the CO Alert triggers, move the generator outdoors and let it air out before restarting.

Can I use the XP9000iH for whole-house backup during an outage?

You can, but only if your home’s essential circuits draw less than the generator’s running wattage (7,600W gas, 7,200W propane). Always use a transfer switch installed by a licensed electrician. Don’t try to backfeed your home through a standard outlet—it’s dangerous and illegal.

How do I maintain my generator for long-term reliability?

Change the oil after the first 5 hours, then every 50–100 hours or annually. Clean the air filter regularly and replace it as needed. Run the generator at least once a month for 20–30 minutes, and use fuel stabilizer if storing gasoline. For winter storage, drain the carburetor and store propane tanks upright in a cool, dry place.

What’s the best way to monitor generator performance remotely?

The XP9000iH doesn’t have built-in Wi-Fi, but you can use a smart plug with energy monitoring or a Bluetooth generator monitor plugged into an outlet. These let you track power output and runtime from your phone. Just be sure any device you use is rated for the generator’s output.

Can I run the XP9000iH in parallel with another generator for extra power?

Yes, but only with a compatible parallel kit and another XP9000iH or approved DuroMax inverter model. Parallel operation lets you double your available wattage for big jobs or whole-home backup. Always follow the manufacturer’s instructions for safe setup.

Are there any advanced safety tips for using this generator?

Always run the generator outdoors, at least 20 feet from doors and windows. Use heavy-duty, outdoor-rated extension cords. Test the CO Alert sensor monthly and check GFCI outlets for proper function. If you use propane, inspect hoses for leaks before every use—never use a flame to check for leaks; a soapy water solution works best.

How do I troubleshoot error codes or warning lights on the digital display?

Consult the owner’s manual for specific codes. Common issues include overload (reduce the load and reset), low oil (top up oil), or CO Alert (move the unit and ventilate). If a code persists, contact DuroMax support for guidance.
