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: What happens with the generator when the local power goes back on?

• <div><p>If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you&rsquo;ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.</p></div>

Q: What is a remote start generator?

• <div><p>These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.</p></div>

Q: What size generator do I need for a 2,500-square-foot house?

• <div><p>A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.</p></div>

Q: How does a generator transfer switch save me money?

• <div><p>It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you&rsquo;ll have to pay between <b>$400 and $2,500</b> to have the transfer switch installed, you&rsquo;ll recoup that amount later on when you don&rsquo;t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect <a href="https://www.angi.com/articles/how-to-hook-up-generator-to-house.htm">hook up of a generator to your home</a>. </p></div>
