What Happens To My Solar Battery During A Power Outage?
If the power goes out during a storm or blackout, your solar battery does more than just sit idle, it keeps your home running. What it powers depends on how you configure your system.
Here’s what you need to know:
If You Have a Battery With Backup Capability
Some battery systems focus solely on energy savings and do not provide backup power. In these cases: When the grid goes down, your system shuts off automatically, including your battery and solar panels. This safety feature prevents electricity from flowing back into the grid, protecting line workers. If you want backup power, ask your installer whether you can upgrade your battery system with backup functionality or a backup gateway.
If You Have a Battery Without Backup Capability
Some battery systems are designed purely for energy savings, not backup power. If that’s the case:
-
When the grid goes down, your system will shut off automatically, including your battery and solar.
-
This is a safety feature to prevent electricity from flowing back into the grid and endangering line workers.
If backup power is important to you, ask your installer if your battery system can be upgraded with backup functionality or a backup gateway.
