In February 2023, a slow freezing-rain storm coated Michigan’s Lower Peninsula in ice and knocked out power to roughly a million homes — one of the worst outages DTE Energy and Consumers Energy had seen in years, with some customers dark for days in the cold. That storm was a reminder of something Michiganders already know: ice, not wind, is what takes this grid down hardest. Michigan’s Lower Peninsula runs inside the MISO grid, and every winter the same threat returns to Detroit, Grand Rapids, and Ann Arbor. If you’re comparing Michigan solar quotes, it helps to know a grid-tied rooftop system shuts off in an outage too — an anti-islanding safety feature — unless you also have storage.
Why ice storms hit the grid harder than wind
A windstorm knocks out power in bursts; an ice storm does it everywhere at once. Freezing rain builds up on conductors and tree limbs until the weight brings them down span by span, so a utility isn’t fixing one big break — it’s fixing thousands of small ones across a whole service territory. That’s why the 2023 event stretched into days for so many households, and why “the power will be back by tonight” so rarely holds after a serious glaze. Planning for a multi-day gap, not a few hours, is the realistic starting point in Michigan.
Sizing backup for the loads that matter
You don’t need to run the whole house. You need the fridge (about 150W), a gas furnace’s blower fan (a few hundred watts), a handful of LED lights (roughly 50W together), the Wi-Fi router (near 10W), and phone charging (about 20W). That’s under a kilowatt of steady draw to keep heat cycling, food cold, and the family connected. A Jackery HomePower 3000 delivers 3,072Wh and 3,600W — enough headroom for all of that — runs near 30 decibels, and is zero-emission and safe indoors, unlike a gas generator that has to sit outside in the ice.

If you have a larger home or want to carry heavier loads through a long DTE or Consumers outage, the Solar Generator 5000 Plus steps up to 5,040Wh and 7,200W with 120V and 240V and expands to 60kWh.

Have it charged before the freezing rain arrives
The homes that come through an ice storm comfortably are the ones that set up backup in advance — charged, tested, and stored in a closet before the forecast turns. Do it now and you’re ready the next time freezing rain moves across the Lower Peninsula. It’s worth checking current deals first.
