Frequently Asked Questions About Sofar Battery
1. How Does a Sofar Battery Work?
A Sofar Battery stores excess solar energy produced during the day.
Instead of exporting all unused electricity back to the grid, your battery saves it for later use—such as during the evening when solar panels stop producing power.
This means:
Daytime → Solar powers home + charges battery
Nighttime → Battery powers home
This helps maximise your solar investment.
2. Can a Sofar Battery Power My Whole House?
Yes—but it depends on:
- Your battery size
- Your daily energy usage
- Which appliances are running
A larger battery like a 15kWh–30kWh system can support most household needs overnight, while smaller batteries may focus on essential appliances like:
- Lights
