When the power goes out, a reliable generator can keep your home running smoothly. Home Depot offers a wide range of generators, from small portable units to large standby systems. But how much do generators cost at Home Depot? The price varies depending on type, power output, and features. In this guide, we’ll break down generator costs, explain key electrical concepts, and help you choose the best option for your needs.
Types of Generators Available at Home Depot
Home Depot sells several types of generators, each designed for different power needs. Understanding these types will help you make an informed decision.
Portable Generators
Portable generators are the most affordable and versatile option. They run on gasoline, propane, or diesel and can power essential appliances during an outage. Prices typically range from 400 to 2,500, depending on wattage.
Small (1,000–3,500 watts) : Powers lights, a fridge, and small electronics. Cost: 400–800.
Medium (3,500–7,500 watts) : Can run a sump pump, AC unit, or multiple appliances. Cost: 800–1,800.
Large (7,500+ watts) : Suitable for whole-house backup (with selective circuits). Cost: 1,800–2,500.
Inverter Generators
Inverter generators are quieter, more fuel-efficient, and produce cleaner power for sensitive electronics like laptops and TVs. Prices range from 500 to 4,000.
Small (1,000–2,000 watts) : Good for camping or small appliances. Cost: 500–1,200.
Large (3,000–7,500 watts) : Can power an RV or several home appliances. Cost: 1,200–4,000.
Standby Generators
Standby generators automatically turn on during an outage and power the entire home. They run on natural gas or propane and require professional installation.
7,000–20,000 watts Cost: 2,000–6,000 (unit only).
Full installation cost 10,000–15,000 (including labor and wiring).
Solar Generators
These eco-friendly generators use solar panels and batteries instead of fuel. They are silent and emission-free but have limited power output.
Small (500–1,500 watts) Cost: 500–2,000.
Large (2,000+ watts) Cost: 2,000–5,000.
Factors That Affect Generator Costs
Several factors influence how much you’ll pay for a generator at Home Depot:
Power Output (Wattage)
The more watts a generator produces, the higher the price. To estimate your needs:
- Add up the wattage of essential appliances (fridge: 600W, AC: 1,500W, etc.).
- Choose a generator with 20–30% extra capacity for safety.
Fuel Type
Gasoline : Cheaper but less efficient.
Propane : Longer shelf life, cleaner burning.
Diesel : More durable but noisy.
Dual-fuel : Runs on gas and propane (more flexible).
Brand & Features
Well-known brands like Generac, Honda, and Champion cost more but offer better reliability. Additional features like:
- Electric start (easier to turn on).
- CO detection (safety shutoff).
- Wi-Fi monitoring (remote control via app).
How to Choose the Right Generator
Determine Your Power Needs
Basic backup (lights, fridge, phone charging) : 3,000–5,000W.
Whole-house backup : 10,000W+ standby generator.
Consider Runtime & Fuel Efficiency
- Portable generators run 6–12 hours per tank.
- Inverter models are 30–50% more fuel-efficient.
Think About Noise Levels
Standard generators: 65–75 decibels (like a lawnmower).
Inverter generators: 50–60 decibels (quieter, better for neighborhoods).
Installation & Maintenance Costs
Portable Generators : No installation needed (just plug-in).
Standby Generators : Professional installation (5,000–10,000).
Maintenance : Yearly servicing (100–300) for standby units.
Conclusion
Generators at Home Depot range from 400 for a basic portable model to over 15,000 for a fully installed standby system. The right choice depends on your power needs, budget, and preferred fuel type. Portable generators are great for short outages, while standby generators provide seamless, automatic backup. Before buying, calculate your wattage needs, compare fuel options, and consider long-term costs like installation and maintenance. With the right generator, you’ll never have to worry about power outages again. Visit your local Home Depot or check online for the latest deals and inventory!
