You may wonder why your solar system shuts off when the grid goes down. During power outages, the utility grid also mandates solar systems to turn off. This prevents the ability for your solar system to feed power to the grid and to your home/ business. A solar storage battery system can automatically isolate your solar system from the grid and will keep your family and business up and running.

When looking to choosing the right solar battery, you want to look at the battery chemistry, depth of discharge (DoD), life cycles, efficiency, and cost. Fortress Power focuses on safe and long-lasting Lithium Iron Phosphate (LFP or Life04) technology, which is designed to last 15+ years. Our large network of well-trained installers will provide you a customized solution based on your need.
