Are you prepared?
Backup battery power with- or without solar installation can make the difference in keeping your family safe during unexpected, unusual, unpredictable, severe or unseasonal weather.
Climate change events that threaten the Electric Power Grid are on the rise. Serious weather events will lead to power outages that, if sustained, will lead to loss of perishable foods, loss of income for home office or business, damage to your home plumbing system, data loss, etc. Traditionally home- and business owners would rely on gas- or diesel powered generators during outages. As these generators are not often in use they can have start up problems right at the moment when you need them the most. Generators can therefore become unreliable, and costly to maintain.
Going off-grid? Or find the hybrid middle of the road.
Let’s face it going off-grid means commitment to a different life-style and that is not for everyone. But maybe you already have reduced your power consumption and or you are somewhere on the road to it.
Wherever you are in your journey to a greener future, there will be a solution for everyone and more and more Americans are choosing the security of a battery backup system to keep their family’s save.
In-home batteries work by storing electricity for when you need it and will save money with or without a solar system. Homeowners can charge the batteries during the off-peak hours when the cost of power is lower. Of course charging the batteries with clean solar power is the best solution from a financial as well as an environmental point of view. Battery back up complements a solar system by saving up clean power for the quiet and dark hours of the day.
Hybrid systems are configurations where the battery backup system can be charged either with the grid and with solar. This has a big advantage over a Grid-tie only system as the power companies require the grid-tie system to shut down during a power outage to protect the line workers. The Grid-tie system will not power your house during an power outage. A hybrid system will not shut down during a power outage as it will immediately switch over to battery backup. Most likely you will not even know there was a power outage as the switch time is nearly instantaneous.
However you choose to charge the battery, with a battery backup system you are prepared for the increase of weather related disasters.
So what is the right battery backup for me?
The choice between conventional lead acid and lithium-based batteries has been made much easier for the homeowner. Safety first, lead acid batteries may release dangerous gases. And more facts, lead acid batteries can only be discharged 50 percent and will only last about 500 to 1000 full charging cycles, depending on the design, while high quality lithium batteries can last about 6000 full charging cycles.
Depending on your usage this translates to 7 years life of a lead acid battery and 20 years for a well-designed lithium battery.
Comparison table in general figures for 10 usable KWh:
|Battery type||Lead-acid||Partial Charge Carbon||Lithium|
|Maintenance & Battery replacement||2500 + 2500||0||0|
|Total Cost of owner ship over 10 Years||15,000||12,500||15,000|
|Full charge cycles||1200||2800||6000|
|Warranty||3 Years||5 Years||10 Years|
|Battery bank weight||1000 lbs||1000 lbs||400 lbs|
In summary: Lead-acid batteries have a place in solar and are a tried-and-true technology that cost less but require maintenance and don’t last long. Lithium batteries have a much longer life span and very high efficiency. But these advantages come with a higher price tag.
A better battery backup solution and why we use them
Innovation is key in the solar industry. The Fortress Power lithium ferrite phosphate (LFP) battery bank is the latest addition to the wide array of innovative solar energy equipment we offer. When compared to lead-acid batteries, and gas-generators, the LFP battery bank doesn’t expose the environment, or your family, to harmful gases or chemicals.
Battery banks for off-grid and hybrid systems are not new, but the type of battery you choose impacts the overall efficiency of your system.
The Fortress Power LFP battery bank improves efficiency, via storage capacity and power output, and is safer for off-grid and hybrid systems.
Here are a few reasons why we like this battery bank:
- LFP batteries will not explode or catch fire because they use stable chemical compounds.
- LFP batteries have been proven to be longer lasting and greener than lead-acid batteries without sacrificing power or reliability
- Grant a 100% depth of discharge whereas lead-acid batteries only offer a 50% depth of discharge.
- LFP batteries cost less per cycle.
- LFP battery banks will give you more reliable power that is less wasteful and less harmful to the environment than lead-acid batteries.
When to choose for a Generator
When you need a larger load covered like a whole house Heat Pump, Base board heating (resistance heat) you can opt for a generator. Also combined systems (Battery and Generator) have a place when you have critical/large loads for medical reasons like hospitals or financial firms that have crypto currency servers.
