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: What types of fuel do generators take?

• <div><p>Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:</p><ul><li><p>Natural gas: $2,000&ndash;$21,000 per year </p></li><li><p>Liquid propane: $2,000&ndash;$21,000 per year</p></li><li><p>Diesel: $3,000&ndash;$20,000 per year</p></li><li><p>Gasoline: $500&ndash;$3,000 per year</p></li><li><p>Solar generator: $2,000&ndash;$25,000 per unit</p></li><li><p>Battery backup: $10,000&ndash;$25,000 per unit</p></li></ul><p></p></div>

Q: How long can a whole-house generator run continuously?

• <div><p>Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.</p></div>

Q: Do you need a permit to install a permanent or whole-house generator?

• <div><p>In most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home generators. A permit for a generator usually costs between <b>$50 and $250</b>, depending on where you live. Your electrician or certified generator installer will usually pull the permit for you&mdash;and might be required to do so by your building department&mdash;but you&rsquo;ll be on the hook for the cost of the permit. You should ask your installer before agreeing to any work if they will pull the necessary permits for your project.</p></div>

Q: How do I know what size of whole house generator to choose?

• <div><p>Generators are usually sized by running watts and starting watts. Ideally, you&rsquo;ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. <a href="https://www.angi.com/articles/electrical-load-calculation.htm">Calculate your home&rsquo;s electrical load</a> based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.</p></div>
