Generac XD5000E Diesel Portable Generator
This diesel-powered unit is designed for portable, reliable power on jobsites or remote locations. It offers 5,000 running watts with a 6% total harmonic distortion for clean operation of tools and electronics, and a 12-gallon fuel tank delivering extended runtimes. Best for contractors who need steady diesel power on the go. A potential limitation is the weight and transportation requirements on uneven terrain, even with a lifting eye.
Westinghouse 13500 Peak Watt Dual Fuel Generator
Versatile dual-fuel power with high peak wattage and substantial running watts. It supports gasoline and propane, plus remote start features and a transfer-ready configuration. This unit suits homeowners seeking flexible fuel options and a broader outlet selection. A consideration: fuel economy varies between gas and propane, and the unit’s heavier load may require careful handling and storage.
DuroMax XP13000HX 13,000-Watt Dual Fuel
This model provides significant whole-home power backup with dual-fuel support (gasoline or propane). It emphasizes longevity with copper windings and CO alert for safety. Best for households needing strong peak capacity with fuel flexibility. A caveat is that propane can be less energy-dense than gasoline, which may affect runtime depending on fuel type and load.
Generac Guardian 22kW Home Generator
Designed for whole-house protection with WiFi monitoring, this 22kW standby generator is ideal for homes requiring automatic transfer and remote oversight. It supports natural gas or propane and includes a long-term warranty framework. This option shines for homeowners prioritizing continuous power and smart diagnostics, with the trade-off of a larger initial setup and installation cost.
Generac 200 Amp Next Gen Automatic Transfer Switch
This transfer switch enables automatic whole-home backup by transferring the entire 200-amp load to a compatible standby generator when utility power is interrupted. It includes hardened brownout protection to prevent false transfers and supports full 120/240V load coverage. Best for seamless, automatic home power without manual intervention. A limitation is that it must be paired with a compatible standby generator to deliver full capability.
Buying Guide: Key Purchase Considerations
- Power needs: Determine whether you need portable diesel power (for worksites and mobility) versus a stationary standby solution for a home. Consider both running watts and peak watts to ensure your essential circuits stay powered.
- Fuel type and availability: Diesel offers good fuel efficiency and long runtimes on the right tank capacity, while dual-fuel units give flexibility with gasoline or propane. Factor fuel supply reliability in your area.
- Transfer and protection: For homes, an automatic transfer switch (ATS) provides seamless handoff when power fails. Look for units with brownout protection and full-load transfer capabilities.
- Outlets and compatibility: Ensure the generator or transfer switch supports your home’s receptacles and your appliances. Consider GFCI outlets for outdoor use and RV-ready connections if needed.
- Runtime and fuel capacity: Larger tanks or higher-efficiency engines extend runtime, reducing refueling frequency during outages or heavy workloads.
- Remote monitoring: WiFi or app-based monitoring helps track status and maintenance without onsite checks, especially for standby systems.
- Installation considerations: Standby systems require proper placement, venting, and electrical connection work. Portable units should have secure transport and stable setup on uneven surfaces.

Diesel engines typically offer robust durability, fuel efficiency, and longer lifespans under heavy loads, which is beneficial for continuous or remote operation.
Yes, dual-fuel units provide flexibility to switch between gasoline and propane, which can improve fuel availability and cost management depending on supply.
For most homeowners, an ATS provides automatic power transfer, reducing manual intervention during outages and improving convenience and safety.
Calculate essential loads (HVAC, refrigerator, sump pump, lights) and add a margin for startup surges to avoid tripping or underpowered circuits.
Yes, place units on stable, level surfaces with adequate clearance, and follow ventilation and CO safety guidelines to prevent risks in enclosed spaces.
Propane and natural gas can be convenient for standby systems, but ensure fuel availability and proper fuel line sizing to sustain runtime during prolonged outages.
