When we think about the abundance of energy the sun provides during the day, it’s not always obvious why you may want to consider adding a backup battery to your solar energy system. If you fall into that camp, you’ll likely benefit from looking at some of the main reasons people choose to add Enphase Storage to their system.
But first, let’s take a refresher on our backup battery, Enphase Storage, and how backup power works.
How backup batteries work.
Your solar panels often generate more energy than you need to consume in a given hour or day. If you don’t have a backup battery, that overproduction is sent back to the utility grid. If you do have a backup battery, some of that energy is harnessed and stored inside the battery, for later usage when your solar panels aren’t producing power.
When your solar panels stop producing — whether it’s at night or due to a power outage — your home solar system can shift from drawing its power from panels to drawing from the battery, rather than being forced to draw from the utility company.
