In New Hampshire, power outages are part of life, especially during winter storms. If you’ve ever lost power, you know how disruptive (and sometimes dangerous) it can be. Luckily, with a backup battery system, your home doesn’t have to lose power when the grid goes down.
At Granite State Solar, we offer three trusted backup battery options: Enphase, Franklin WH, and Powerwall. Keep reading to learn how these systems work during power outages.
1. Automatic Detection
When a power outage occurs, the grid stops supplying electricity to your home. If you have solar, your system immediately disconnects from the grid to prevent electricity from being sent back through power lines while utility crews are working. Within seconds of the grid going down, your backup battery system detects the outage and takes over.
2. Seamless Power
The transition to battery power is nearly instant, most homeowners won’t notice more than a brief flicker of lights.
Your essential circuits, or even your entire home, can stay powered depending on the size of your system. How long your battery can run your home also depends on its capacity. The more kWh of storage you have, the longer you’ll have power during an outage. Some systems provide power for a few hours, while others can last several days.
When designing your system, our team considers how much power you want available during outages, so you’re covered when it matters most.
3. Monitoring Capabilities
You can monitor your battery system through an app. Each system we install offers its own monitoring platform, allowing you to see your stored energy in real time. You can also turn the system on or off and adjust which circuits it’s connected to, helping you conserve energy as needed during an outage.
4. Automatic Return to Grid or Solar
4. Automatic Return to Grid or Solar
Once the grid is restored, your battery system automatically detects it and your home switches back to solar or grid power. It’s that simple.
