Choosing the right generator size is one of the most important steps in protecting your home or business from unexpected power outages. Too small, and your generator won’t keep up with your needs; too large, and you’ll spend more on fuel and installation than necessary. At Wolverine Electrical Contracting in Niles, Michigan, our licensed electricians help residential and commercial clients find reliable generator solutions built for long-term performance and efficiency.
Step 1: Determine Your Power Requirements
Start by listing the essential appliances and systems you want to power during an outage. This usually includes lighting, HVAC, refrigerators, freezers, sump pumps, and medical or office equipment for businesses. Each device has a wattage rating, usually found on a label or in the owner’s manual.
Add up the wattage of all the items you plan to run at once. Because motors and compressors often require an extra surge (starting watts), account for these temporary peaks by adding about 20–30% more power to your total.
Step 2: Calculate Total Wattage
Once you have the wattage details, you can estimate the right generator size. For most homes, a 7,000–10,000-watt generator is sufficient to power lights, refrigerators, and a furnace. Larger homes or small businesses often need a 20,000–25,000-watt generator to handle multiple HVAC units, security systems, and work equipment simultaneously.
If you’re not sure how to perform these calculations or want professional insight, consider reaching out to our team of skilled electricians who specialize in commercial electrical and electrical contracting services in Niles, Michigan. Our experienced staff can help conduct an accurate power assessment and recommend the ideal unit for your property.
Step 3: Choose the Right Type of Generator
There are two main generator types to consider: portable and standby. Portable generators are affordable and flexible but require manual setup and refueling. Standby generators automatically activate during an outage and connect directly to your electrical system, offering seamless power and convenience for both homes and businesses.

Step 4: Don’t Forget About Maintenance and Service
