Q: 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&rsquo;s natural gas supply are the best option for extended usage, as these won&rsquo;t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won&rsquo;t last as long, as these require fuel storage and regular refueling to stay running.</p></div>

Q: What are the benefits of a portable generator?

• <div><p>Portable generators provide backup power for essential appliances during outages and are easy to relocate.</p></div>

Q: Can you use biofuel in a whole-house generator?

• <div><p>In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.</p></div>

Q: How much does it cost to install a generator?

• <div><p>The typical <a href="https://www.angi.com/articles/how-much-does-it-cost-install-generator.htm">cost of a home generator</a> is around <b>$5,000</b>, but prices range from <b>$400 up to $13,000</b>, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between <b>$500 and $2,000</b> or a partial-home generator for between <b>$2,000 and $6,500</b>. Whole-home generators usually total between <b>$5,000 and $13,000</b>, with some models climbing as high as <b>$18,000</b>.</p></div>

Q: What size of diesel generator do you need to run a house?

• <div><p>Sizing a generator is a careful process that requires calculating the <a href="https://www.angi.com/articles/electrical-load-calculation.htm">electrical load</a> of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.</p><p>In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. </p></div>
