With the average home drawing 750 to 1,000 W of power per hour during a blackout, the 10 kWh battery will last 10 to 12 hours and the 13. Wh battery will last 13. Therefore, it can run most homes on an average day without much trouble (although energy generation can differ based on sunlight hours and season). A 10kW system can power smaller homes off-grid as long as they consume 25kWh per day in total.For a home with low to moderate energy use, such as a couple living in a 3-bedroom house with energy-efficient appliances, a 10kWh battery might provide them with reliable power throughout most of the night.
