Q: What size whole house generator do I need to run central AC?

• <div><p>To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right <a href="https://www.angi.com/articles/whole-house-generator-sizing.htm">generator size</a>. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.</p></div>

Q: Do I need a permit to install a portable generator?

• <div><p>You may need a permit for a portable generator if you&rsquo;ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.</p></div>

Q: How much energy can I expect a home wind turbine to generate?

• <div><p>Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home&rsquo;s needs. Accurate output estimates require a professional wind assessment and a review of your household&rsquo;s energy usage patterns.</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>
