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

Q: Can you use your electric car as a backup battery?

• <div><p>If you&rsquo;re wondering <a href="https://www.angi.com/articles/using-electric-car-as-home-generator.htm">if you can use your electric vehicle as a backup battery</a>, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.</p></div>

Q: Where can you install a whole-house generator?

• <div><p>Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.</p></div>
