Don't Be Left in the Dark: Lithium Batteries Provide Backup Power When You Need it Most

Posted September 28, 2018

Blackouts can occur anytime. Whether it’s a natural disaster, like a hurricane, a tree limb falling on a wire or an animal coming in contact with equipment, a power outage is never convenient. Having the appropriate backup power during outages can help you worry less and give your household the power needed for your essential devices.

You may be wondering, what is the best backup power solution?

For decades, lead acid batteries have been the most widely adopted batteries for renewable energy systems. However, a shift is occurring as more users discover the advantages of lithium iron phosphate batteries (LiFePO4). They are now widely used to power homes and are gaining popularity as residential back up due to their many advantages.

What Makes LiFePO4 an Ideal Solution for Backup Power?

One shortfall of solar power systems in general is that they aren’t able to fully charge your batteries without adequate sunlight. If this happens enough, it will significantly and permanently reduce the available energy from your lead-acid battery bank and it will dramatically shorten its life. But the technology behind lithium iron phosphate battery storage has addressed this problem. LiFePO4 batteries can operate in a partial state of charge without any damage to the battery performance or life.

LiFePO4 batteries also provide more usable energy. Lead acid batteries are typically over-sized up to two times your energy needs to account for extended periods without sun and less usable energy with higher rates of discharge. Plus, you are usually cautioned to limit your use to 50% of the rated capacity, as using more will significantly reduce life. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge.

And there’s more! The primary benefit of using LiFePO4 for your solar or back up system, is the total number of cycles they provide. LiFePO4 batteries are designed to provide around 7,000 to 8,000 cycles, even at an 80% depth of discharge each cycle. That is over 20 years of use if they are deeply cycled every single day!

When To Use A Backup Power Source

Lithium battery storage systems are very useful during power outages. When your electricity goes out, LiFePO4 technology provides you with backup power to run your lights and appliances. You even have complete control over when to use your electricity.

Having a backup power source also helps you combat high energy prices during peak demand hours. So, you are able to store solar power when energy rates are inexpensive and use your charged lithium solar batteries when energy rates soar.

Having a backup power source is a small price to pay for the peace of mind you have knowing that life continues in your home during an outage. LiFePO4 batteries are an excellent choice for backup power. They deliver highly-efficient, ultra-long life and constant power you can depend on in even the most extreme circumstances.
