How many days can a standby generator run continuously?

• <div><p>The <a href="https://www.angi.com/articles/how-long-can-whole-house-generator-run-continuously.htm">amount of time a standby generator can run continuously</a> is around <b>3,000 hours</b> on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.</p></div>

What size generator do I need for a 1500-square-foot house?

• <div><p>A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the <a href="https://www.angi.com/articles/how-many-watts-house.htm">total wattage</a> of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.</p></div>
