Natural Gas Conversion Kit for Duromax XP12000EH
This kit enables a natural gas inlet through an existing carburetor port, avoiding permanent modification and preserving gasoline operation. It is designed for the Duromax XP12000EH and offers straightforward switching between gas and gasoline. Best for DIY installation-friendly users who already own a XP12000EH and want a dedicated natural gas option.
Best for: Homeowners or builders who already own the XP12000EH and want a low-friction way to run on natural gas when gas lines are available. It’s a practical upgrade without giving up gasoline versatility.
Limitation: Requires re-connection of the stock propane hose to switch back from natural gas to propane or gasoline. Installation familiarity with carburetor ports is recommended.
WEN 14,500-Watt Tri-Fuel Generator
The WEN TF-1450X supports gasoline, propane, and natural gas with a simple selection dial. It operates at 120V and 240V, making it suitable for transfer switches and general backup use. It includes a CO watchdog for automatic shutdown in dangerous conditions. Best for: Homeowners who need a flexible, transfer-switch-ready unit with integrated safety features and a straightforward fuel-switch process.
Limitation: This unit is heavier and may require more space and handling than compact portable models. The tri-fuel capability is substantial, but the unit’s size can affect placement in smaller properties.
Champion 6500-Watt Tri Fuel Portable Inverter
The Champion tri-fuel inverter runs on natural gas, propane, or gasoline, with hoses included for natural gas (25 ft) and propane (6.6 ft). It supports remote and push-button electric starts, and can connect to energy storage or automatic transfer switches. Best for: Users seeking convenient wireless starts and a compact tri-fuel option for portable, residential backup or RV use.
Limitation: While versatile, its peak output is lower than some larger tri-fuel units, which may limit operation of multiple high-demand appliances during a broad outage.
DuroStar DS13000MXT Tri Fuel Generator
With 13,000 watts of power, the DS13000MXT is designed for whole-home backup. It uses tri-fuel technology and includes a push-button start and a transfer switch-ready outlet. Best for: Households with significant power needs where a robust, flexible fuel strategy supports essential circuits and high-demand appliances during outages.
Limitation: It is a heavier, bulkier unit, which can complicate mobility and storage in tight spaces.
Champion 10,000-Watt Tri Fuel Open Frame Inverter
This open-frame inverter generator supports natural gas, propane, or gasoline with included hoses for natural gas and propane. It features an electric start, a cold-start capability, and low harmonic distortion (less than 3%), making it reliable for electronics and EV chargers. Best for: Events or homes needing quiet operation and consistent power for sensitive devices while retaining fuel flexibility.
Limitation: Open-frame designs can be less stable in high wind or outdoor conditions without proper mounting or shelter, and the power ceiling is lower than some standby-grade units.
Buying Guide
What fuels do tri-fuel generators support, and why choose them?
Tri-fuel units accept gasoline, propane, and natural gas. This flexibility is valuable when one fuel type becomes scarce or expensive. It also helps ensure power during emergencies when a single fuel supply might fail.
How to choose by power needs
- Small homes or apartments: look for 6,500–10,000 watts with efficient inverters for sensitive electronics.
- Whole-home backup: target 12,000–13,000 watts or more with a transfer switch-ready design.
- Portability vs. permanent setup: weigh open-frame versus portable inverter units against wheeled or stationary configurations.
Safety and installation considerations
- Ensure proper ventilation and CO safety features, especially with natural gas connections and enclosed spaces.
- When using natural gas, verify compatibility with your home’s gas line pressure and local codes.
- Install transfer switches or automatic generators only according to local electrical codes and manufacturer guidelines.
Fuel availability and hose lengths
Some models include hoses for natural gas (commonly 25 ft) and propane (around 6–26 ft). Longer hoses enable greater placement flexibility but can affect performance and safety if not rated for fuel flow and pressure.
Maintenance and warranty considerations
Tri-fuel systems require regular fuel system maintenance and periodic carburetor checks. Pay attention to component accessibility, ease of starting, and availability of replacement parts in your region.
Practical comparison tips
- Best for high power and home backup: DS13000MXT or TF-1450X with higher running watts and transfer switch readiness.
- Best for compact spaces and portability: Champion 6500-Watt or Champion 10,000-Watt open frame for flexible use outdoors.
- Best for existing XP12000EH owners: natural gas conversion kit provides a low-friction fuel switch without a full new unit.
FAQs
- What does tri-fuel mean? It means the generator can run on gasoline, propane, or natural gas.
- Do natural gas generators require permanent conversion? Some models offer conversion kits or factory tri-fuel capabilities; check if your unit supports a non-permanent natural gas setup.
- Can I run a natural gas generator indoors? No. Ensure proper outdoor ventilation and safe exhaust routing according to manufacturer instructions.
- What is a transfer switch, and why is it important? A transfer switch isolates your home from the grid and prevents back-feeding; it enables safe, automatic power routing to selected circuits during an outage.
- Are longer hoses safer for fuel connections? Longer hoses provide placement flexibility but must be rated and installed per safety standards to avoid leaks or pressure issues.
