Output capacity and running watts
Add up the running watts of the loads you want during an outage, then add a margin for startup surges. A refrigerator may need several times its running draw at startup, and a well pump or sump pump can spike similarly. Size to the sum of your essential circuits, not to the largest number on a box.
Good picks for this: Generac 14kW Whole Home Generator, DuroMax XP13000HX
Fuel type and storage
Gasoline degrades in storage, while propane keeps almost indefinitely in sealed tanks. Dual fuel units give flexibility. Check local code for fuel storage limits before buying.
Good picks for this: DuroMax XP13000HX, Westinghouse 6500 Watt Dual Fuel Home Backup Portable Generator
Transfer switch compatibility
A transfer switch lets you power house circuits safely and prevents backfeeding the utility grid. Without one, you are limited to extension cords, which is risky. Confirm whether the unit includes an automatic transfer switch or is only transfer-switch ready.
Good picks for this: Generac 22kW Whole Home Generator, Westinghouse 6500 Watt Dual Fuel Home Backup Portable Generator
Noise level and inverter design
Inverter generators typically run quieter and produce cleaner power than open-frame units. If neighbors or sleep matter, weigh noise heavily.
Good picks for this: Oxseryn Power Equipment 4400 Watts Inverter Generator, Oxseryn 4400-Watts Inverter Generator
Portability and placement
Portable units must sit outdoors, away from windows and doors, with clearance on all sides. Consider how you will move the unit and whether you have a dry, covered spot for it.

Safety features
Carbon monoxide is the main hazard with any combustion generator. Look for built-in CO sensors and auto shutoff. Install battery CO alarms in the home regardless of what the generator includes.

Installation and long-term maintenance
Permanent units require professional installation and periodic service. Portable units need oil changes, fuel stabilizer, and test runs. Plan for maintenance before the first storm season.

FAQ
What size generator do I need to run a refrigerator and sump pump?
Most standard refrigerators run at a few hundred watts but surge higher at startup. A sump pump often needs a few hundred to over a thousand watts at startup. Add the running loads and allow margin for surges. Consult a licensed electrician for a load calculation.
Can I plug a portable generator directly into a wall outlet?
No. Backfeeding through a wall outlet can injure utility workers and damage equipment. Use a properly installed transfer switch or power individual appliances with heavy-duty extension cords rated for outdoor use.
Where should I run a gas generator?
Operate it outdoors, at least 20 feet from the house, with the exhaust pointed away from doors and windows. Never run it in a garage, even with the door open.
Is propane better than gasoline for home backup?
Propane stores longer and burns cleaner, which many owners prefer for standby use. Gasoline is easier to find in some areas. Dual fuel units let you choose based on what you have on hand.
Do I need a permit for a whole-home generator?
Often yes. Permanent installs usually require permits and inspections, and gas connections need licensed work. Check with your local building department before purchase.
How long can a generator run during an outage?
Runtime depends on fuel capacity and load. Manufacturers list runtime at specific loads, so check the spec for your planned usage. Plan for refueling or propane deliveries during extended events.
Conclusion
For most whole-house needs, the Generac 14kW Whole Home Generator is the most straightforward choice, with the 22kW model for larger homes. Dual fuel portable units such as the DuroMax XP13000HX suit owners who want flexibility without a permanent install. The Westinghouse 6500 is a practical budget-minded portable option. Inverter units from Oxseryn fit quiet, electronics-friendly backup and RV use. Match output to your essential loads, confirm transfer switch readiness, and consult a licensed electrician before any installation.
