Q: Can a portable generator power an entire home?

• <div><p>A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a <a href="https://www.angi.com/articles/installing-whole-house-generator.htm">whole-home generator</a> instead. </p></div>

Q: How much does portable generator installation cost?

• <div><p>Costs range from $500 to $2,500, depending on generator type and installation complexity.</p></div>

Q: Do installations include unit assembly?

• <div><p>Many services include assembling the unit and securing it in the window. Confirm with your provider.</p></div>

Q: How much horsepower do I need?

• <div><p>If your home already has a grinder pump and you&rsquo;re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.</p></div>

Generator Install questions, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

1,000 sq ft: 6–9 kW
1,500 sq ft: 7–10 kW
2,000 sq ft: 10–14kW
2,500 sq ft: 12–16kW
3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

Many services include assembling the unit and securing it in the window. Confirm with your provider.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.
