It is transfer switch ready, enabling quick connection to home electrical systems. The design supports extended runtime on its sizable tank and includes safety features such as rubber-covered outlets for weather resistance and a digital hour meter to monitor usage.
DuroStar DS13000MXT Tri Fuel Portable Generator
The DS13000MXT tri-fuel model provides robust power with 13,000 watts on gasoline, and flexible operation on propane or natural gas. It’s designed for whole-home power backup and includes a transfer switch-ready configuration with a 50-amp outlet. The unit emphasizes CO alert safety, a push-button start, and a full power panel with a selection knob to switch fuels and manage outlets. It targets larger homes or frequent outage scenarios where maximum resilience is essential.
Buying Guide: Key Purchase Considerations
- Fuel flexibility: Tri-fuel models offer options for gasoline, propane, or natural gas, useful during fuel shortages or price surges. Consider your typical fuel availability and storage capacity.
- Transfer switch readiness: Confirm the generator includes a transfer switch connection or is compatible with a NEMA transfer switch panel to ensure safe isolation of the home from the grid.
- Power needs: Evaluate running watts (continuous load) and peak watts (surge capacity). Prioritize models with higher running watts if you plan to power essential appliances (refrigerator, furnace, sump pump) concurrently.
- Runtime and tank size: Larger fuel tanks extend runtime at half-load. If outages last many hours, prioritize models with extended endurance per tank and efficient fuel use.
- Electrical safety features: Look for CO shutdown sensors, automatic low-oil shutdown, and rubber-covered outlets for weather resistance in outdoor conditions.
- Starting mechanism: Electric start with a manual backup, wireless or keypad options can improve accessibility during emergencies when manual cranking is impractical.
- Sound and footprint: Consider noise levels and the unit’s footprint, especially if you have limited outdoor space or need to place the generator near living areas.
- Outlets and compatibility: Ensure the generator has the correct 120V and 240V outputs, plus dedicated transfer switch-ready receptacles (L14-30R, 14-50R) compatible with your panel.
- Maintenance and warranty: Review oil changes, filter replacements, and warranty duration for long-term reliability during frequent outages.
- Safety and certification: Verify compliance with local codes and the presence of safety features like automatic shutoffs and CO detectors to protect occupants.
