How Long Will a 10kWh Home Battery Last on Long Island?
In an optimal configuration, a 10kWh solar battery installation could provide around 10 to 12 hours of backup power. This size is often considered the sweet spot for a battery energy storage system. It’s enough to provide backup power in an emergency, while also helping to balance loads and optimize savings on regular days.
10kWh Solar Battery Runtime – Compare Runtime by Scenario
While every home is unique, you can compare typical runtimes based on how you use a solar battery.
| Type of Usage | Appliances and Devices | Estimated Runtime |
| Essential | Refrigerator, lights, Wi-Fi, phone charging. | Up to 24 hours. |
| Moderate (Most Homes) | Essentials + TV, laptop, ceiling fans. | 10 – 12 hours. |
| High-Demand | Essentials + Microwave, dishwasher, coffee maker, and other appliances. | 3 – 5 hours. |

Can I Buy a Bigger Battery for Longer Runtimes?
Yes, you can invest in a larger solar battery to increase the amount of stored energy and runtime hours. The downside to this is the cost. A solar battery installation on Long Island should balance costs relative to your needs. Buying a larger battery increases the amount of backup power you will have, but also increases the time it takes for your system to pay for itself.
The best solar installers, like the team at Power Solutions, will balance the cost and utility of a battery system to ensure that your home has outage protection without diminishing your long-term returns. Most homes opt for a moderate backup, where essentials and some electronic appliances/devices can run for about 12 hours. This covers the most likely blackout and brownout scenarios on Long Island.
