Understanding Wattage and Your Needs
When selecting a whole house portable inverter generator, understanding wattage is crucial. You need to calculate the starting and running wattage of all appliances you intend to power simultaneously. For instance, a refrigerator might require 600 running watts but 1800 starting watts. The Westinghouse iGen5000DFc, with its 5000 peak watts and 3900 rated watts, can comfortably handle a combination of essential appliances, such as a refrigerator, a few lights, and a microwave, without tripping. Always consider the surge wattage required to start motors.
Inverter generators are known for producing clean, stable power, which is vital for sensitive electronics. This means you can power your laptop or TV without fear of damage. For example, the WEN 56235i provides 2350 surge watts and 1900 rated watts, which is sufficient for charging phones, running small appliances, and providing backup for critical items during an outage. Its clean power output ensures the safety of your devices.
Fuel Type and Run Time Considerations
Portable inverter generators typically run on gasoline, but dual-fuel models like the Westinghouse iGen5000DFc offer the added flexibility of propane. Propane has a longer shelf life and burns cleaner, which can be advantageous for long-term storage or in situations where gasoline might be scarce. Considering run time is equally important; for example, the Honda EU2200i can run for up to 8.1 hours on a single 0.95-gallon fuel tank, making it efficient for extended use at lower loads.
When planning for whole-house backup, assess how long you might need power. A longer run time per tank means less frequent refueling, which is a significant convenience during an emergency. The WEN RV-Ready 4000-Watt Open Frame Inverter Generator, for example, is designed for efficiency, ensuring you have power when you need it most. Factors like fuel availability and ease of storage should also influence your decision.
Noise Levels and Portability
One of the key advantages of inverter generators is their quiet operation. The Honda EU2200i, for instance, operates at 48 to 57 dB(A), which is comparable to the noise level of a normal conversation. This makes it ideal for residential areas or camping where noise can be a concern. The WEN 56235i is also noted for its extremely quiet operation.
Portability is another crucial factor, especially for “portable” whole house generators. While models designed for whole-house backup might be heavier, they should still be manageable for transport and storage. The WEN 56235i, weighing only 39 pounds, is an excellent example of a highly portable unit. Even larger models like the WEN RV-Ready 4000-Watt are designed to be lighter than traditional generators of similar output. You can find more portable options here.

Frequently Asked Questions
What is the difference between an inverter generator and a conventional generator?
Inverter generators produce AC power, convert it to DC, and then invert it back to clean AC power, resulting in a stable sine wave that is safe for sensitive electronics. They are typically more fuel-efficient, quieter, and more compact than conventional generators, which produce raw AC power directly from the engine.
Can a portable inverter generator power an entire house?
While some high-wattage portable inverter generators, like the Westinghouse iGen5000DFc, can power essential circuits and appliances in a home, they are generally not designed to run an entire house with all its systems simultaneously like a dedicated standby generator. They are best suited for critical loads during outages or for recreational use. For larger power needs, consider higher wattage inverter generators.
Are dual-fuel inverter generators more efficient?
Dual-fuel inverter generators offer versatility by running on both gasoline and propane. While propane can be more convenient for storage and burns cleaner, it typically provides slightly less power output and can be less fuel-efficient than gasoline for the same amount of energy. However, the ability to switch fuel types can be a significant advantage in emergency situations.
How loud are portable inverter generators?
Portable inverter generators are notably quieter than conventional generators. Many models operate within the 50-60 dB(A) range, comparable to a normal conversation. This makes them ideal for environments where noise reduction is important, such as residential areas, campgrounds, or tailgating events.
