What does a home battery do?
Home batteries capture and store solar energy to be used by your home when needed later, such as during a utility power outage. These batteries can be an excellent source of backup power, increase your energy independence, and may even save you money on your electrical bill.

Use the stored energy day or night
Use the stored energy during a power outage
Will a home battery back up my entire home?
No, a home battery cannot power everything in your home. Because of this, a sub panel would be installed with only the most important things in your home, such as lighting, your refrigerator, furnace, etc. to be backed up by this battery.
Daytime Power Outage
With a home battery, you can continue to generate and store solar energy during the day. Excess energy will be sent to the battery. Solar energy would be used to power the items on your sub panel.
Nighttime Power Outage
Your items would be powered by any energy stored in the battery. Depending on how much energy is stored as well as what is being powered will determine how long the battery will power your home. The larger the power consumption, the shorter amount of time.
