Combining the benefits of being on the main utility grid with the confidence of having your own system in place, grid tie battery systems truly provide the best of both worlds. Whether you’ve got a cabin in the mountains that has a tendency to lose power, or you just want to be sure that you’ll stay comfortable if a strong storm rolls through your area, grid tie solar with battery backup keeps your home or commercial building powered even if the main system goes down.
When the grid is running properly, your home or business will use power generated from your solar panels or pull electricity from the grid. Any excess power generated over and above will go back to your utility company for credits on your power bill in areas where net-metering is available.
In the event of grid blackouts, these systems will switch to “off’-grid mode” drawing power stored in your battery bank to power your home AND using your solar panels to recharge your battery bank.
