Power Outage Protection

Why should you be concerned?

The Ecological Threat Register (ETR) shows that the world has witnessed a tenfold increase in natural disasters since the 1960s. Power outages are impacting trillions of people globally. The devastating power outage that occurred in Texas in February 2021 caused 14.5 million people to lose power for almost 10 days. As a result, 700 people died. If the power is out for more than 4 hours, you will start to lose access to essentials resources such as food, water, and medication. Being without power can also cause serious health conditions such as heat stroke, heat exhaustion, heat cramps, fainting, and hypothermia. Hypothermia happens when a person’s core body temperature is lower than 35°C (95°F).

Why Fortress Power is better than Alternative
Back-Up Solutions


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 of 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 LifeO4) 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.
