The “Whole Home” Misconception
There is a myth in our industry that if you have a spacious home here in Oakland County, you need a massive, industrial-sized generator to power it. When the ice weighs down the lines or the winter winds whip through Detroit, homeowners often assume they need a system capable of matching every single lightbulb and appliance running simultaneously to keep the freeze out.
But think about how you actually live during a DTE or Consumers Energy outage. Do you run the microwave, the electric oven, the hair dryer, the furnace, and the clothes dryer all at the exact same second? Probably not. In 2026, we don’t size generators based on “everything on at once.” We size them based on Load Management.
The Traffic Cop in Your Electrical Panel
Think of Load Management as a traffic cop for your electricity. When the generator kicks on, this smart technology prioritizes where the power goes.
Let’s say you have a 24kW or 26kW air-cooled unit—the standard for many homes in Detroit.
The Essentials: Lights, fridge, internet, and TV get power instantly.
The Heavy Hitters: Then, the system looks at your AC units or electric water heater. It allows them to start one by one, rather than all at once, preventing a massive surge that could stall the engine.
This is how we provide “Whole Home” power without installing a massive, expensive liquid-cooled engine in your backyard.
The New Challenge: Electric Vehicles (EVs)
In Detroit, we are seeing more Electric Vehicles in driveways every month. An EV charger is a huge electrical draw—often equal to an entire house worth of power.
Can you charge your Tesla or Rivian on a generator? Yes. But you need a strategy. We install management modules that allow the car to charge only when the house isn’t using peak power. If you turn on the electric oven to cook dinner, the system might temporarily pause the car charger. When dinner is done, the car resumes charging. You don’t have to flip a switch; the system thinks for you.
Sizing Matters
This is why a professional standard of installation is so critical. A “Chuck in a Truck” might just look at your square footage and guess the size.
At Generator Supercenter of Detroit, we perform a load calculation. We look at:
- Your AC Tonnage: How much power does it need to start (not just run)?
- Your Appliances: Are you gas or electric for heat and cooking?
- Your Future: Are you planning to buy an EV or add a hot tub?
Power Smarter, Not Harder
You can have it all—the warm home, the hot shower, and the charged car—even when the ice storms hit. It just takes the right design. Don’t let someone oversell you on a unit you don’t need, or undersell you on one that won’t keep up with our Michigan winters.
