How do solar batteries work?

They work by storing the excess energy generated by your solar panels. This energy can then be used to power your home during a power outage, or at night when your solar panels are not generating electricity. Solar batteries can also be used to reduce your reliance on grid power, which can save you money on your energy bills.

How do you benefit from a solar battery?

There are many benefits to having a solar battery, including:

  • Backup power during power outages: Solar batteries can provide backup power during power outages, so you can keep your lights on and your appliances running.
  • Reduced reliance on grid power: Batteries can help you reduce your reliance on grid power, which can save you money on your energy bills.
  • Increased energy independence:  batteries can give you more energy independence, so you are not at the mercy of the power grid.
  • Increased home value: batteries can increase the value of your home, making it a more attractive investment.
