Battery Storage

Increase your energy independence.

Protect your family and assets in a power outage.

Create your own energy and improve the return on investment for your solar system.

Use your solar production directly

How it works

During the day, solar owners capture the suns energy and use it to power their homes. When paired with battery storage,  excess daytime solar electricity goes directly into your battery system where it is stored for later use. This energy can be used when the sun goes down or saved as a backup in case the grid goes down. 

Install a battery storage system and ensure you and your family don't get left in the dark.

  • Will I have power with solar when the grid goes down?
    Without a battery back-up system, you will not be able to power your home with solar during an outage. For safety, grid-tied solar systems shut off when the electricity grid is down. While grid outages are relatively rare, a battery system is a great way to keep you and your family secure during times of uncertainty. *This is true of all solar systems except the Enphase IQ8 grid-forming micro inverter, which has the ability to provide sunlight backup without batteries.
  • How much does battery storage cost?
    At Astra Solar, we offer three top brands of battery back-up systems (Enphase, SolarEdge & LG Chem). These systems cost between $13,000 to $20,000, including installation. Please reach out for more accurate pricing for your home.
  • What happens to excess electricity if I don't have a battery?
    When you own a solar system, the grid acts as your battery. Excess electricity produced by your system goes back to the MB Hydro grid for credit. When your solar system doesn't keep up, you draw from the grid and use your built up credit.
  • How long can one battery keep my house running in a blackout?
    This depends on the size of your battery and the loads you want powered. Usually only essentials loads or loads with a small electrical draw are backed up. For example: fridge, lights, internet modem, TV, sump pump, etc.
  • Can I charge a battery with a generator?
    Yes, you can.
