LOS ANGELES—Let's face it: The American power grid is a hot mess. The system is outdated and overstressed by amp-sucking appliances, air conditioning units, and extreme weather. Depending on where you live, it's likely only a matter of time before your home will experience a blackout. GM Energy, a subsidiary of General Motors, is here to help.

At a demonstration in a swanky 10,000-square-foot mansion in Beverly Hills, California, where I counted 51 recessed lights in the great room, the new home products from GM Energy easily kept the electrons flowing, eschewing the grid and drawing power from the 200 kWh battery in a 2024 Chevrolet Silverado RST.

It all starts with the GM Energy PowerShift charger. On an 80 A circuit, the charger can charge your EV at a whopping 19.2 kW, and its bi-directional technology can push electrons from the truck's battery into an inverter to convert it to the AC power your home requires. The happy little AC current then goes into the Home Hub that distributes the power to the appropriate circuits, and voilà—the lights are on.
