Q: Is a home generator a tax write-off?

• <div><p>Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.</p></div>

Q: Should I buy a solar battery or a generator?

• <div><p>If you&rsquo;re deciding between a <a href="https://www.angi.com/articles/solar-batteries-vs-generators.htm">solar battery versus a generator</a> for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don&rsquo;t have many ongoing costs. </p></div>

Q: What’s the normal lifespan of a diesel generator?

• <div><p>You can expect a diesel generator to last for up to <b>30,000 hours of use</b>, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. </p></div>

Q: How long can a whole house generator run?

• <div><p>As long as they have enough fuel, whole-house generators can run for weeks at a time (400 to 500 hours) without suffering too much wear and tear. However, this type of extensive use isn&rsquo;t ideal if you want to extend the life of your generator.</p><p>Two important points. First, some generators may need you to periodically check oil levels every day or so and refill as necessary for safe operation. Second, if your generator uses a fuel tank, keep it regularly full so it doesn&rsquo;t suddenly shut off. Many backup generators can run through a full tank in a day when they are powering large portions of a home.</p></div>
