Buying considerations
What to consider
When selecting a home generator, start by calculating the total wattage of the appliances you need to keep running during an outage. Whole‑home standby units like the Generac Guardian are suited for permanent, automatic backup, but they require professional installation and a fuel source such as natural gas. Portable generators give you flexibility and lower upfront cost; focus on fuel type, runtime, and the presence of features like electric start and low‑oil shutdown.
What to consider
Noise level and weight are also important if you plan to store the generator outdoors or need to move it frequently. Inverter models, such as the Honda EU2200i, provide cleaner power for electronics but usually have lower output. Finally, compare warranties and service networks; brands like Generac, Honda and Briggs & Stratton offer extensive dealer support, which can be valuable for long‑term ownership.
Questions answered
Most portable units run 8 to 12 hours at half load on a full tank, while larger standby models can provide 24 hours or more before refueling.
Yes, standby generators must be connected to your home’s electrical system by a licensed electrician to meet code and ensure safety.
