Vanadium Battery for Home

The home of the future is powered by solar energy—but how do we get there? While many homes today have solar panels, the current model is not always reliable or cost-effective. Residential vanadium batteries are the missing link in the solar energy equation, finally enabling solar power to roll out on a massive scale thanks to their longevity and reliability.


Residential vanadium flow batteries can also be used to collect energy from a traditional electrical grid. This allows homeowners to have access to back-up power during outages due to extreme weather and helps control utility costs by collecting power from the electrical grid when rates are lower and storing it for later use during peak consumption times when rates are higher.


Vanadium flow batteries are ideal for powering homes with solar energy. Compared to lithium batteries, StorEn’s residential vanadium batteries are:


  • Able to discharge fully at 100% through the battery’s entire lifetime—there is no degradation of capacity

  • Durable, with an expected lifespan of 25 years or more

  • Low maintenance

  • Sustainable, as the vanadium electrolyte can be reused

  • Cost-effective

  • Non-flammable thanks to their water-based electrolyte

  • Non-explosive

  • Able to operate at low temperatures for both outdoor and indoor use

Homes with solar panels need batteries to store energy collected during peak sun times so it can be used later, when it’s dark, overcast, or during inclement weather. While lithium batteries have represented a leap forward for solar technology, they suffer from fast decay and loss in storage capacity over time. 


Our team at StorEn understood that vanadium flow batteries were the answer to the problems presented by lithium batteries, but existing vanadium battery technology wasn’t ideal for residential applications. Through StorEn’s research and innovation, we have engineered a vanadium flow battery that is 30 percent smaller than other designs with similar energy. This development means that vanadium battery production is easier to scale up for wider distribution. 

StorEn’s patented Multigrids stack design delivers unsurpassed power density with a 50 percent cost reduction in the power side of the battery. Our Equilevels and Resafe technology extends the lifespan of StorEn batteries to over 15,000 cycles, with reduced cost of maintenance and no need for regular service inspections.


By offering the highest power density available with the smallest footprint and a modular architecture, StorEn residential vanadium batteries are well-suited for just about every home and installation requirement. We envision the StorEn home vanadium battery as a plug-and-use product that offers households around the world the ability to be independent from the utility grid. 

Frequently Asked Questions About Vanadium Batteries for Home Solar Systems

How is a vanadium flow battery different from a lithium-ion battery?

Vanadium flow batteries use rechargeable flow battery technology that stores energy, thanks to vanadium’s ability to exist in solution in four different oxidation states. Vanadium flow batteries do not require the use of heavy metals including cobalt. 


Do vanadium flow batteries help reduce residential utility bills?

Yes. Installing a vanadium flow battery will allow you to pull energy from your residential battery, rather than the electrical company, saving you money on monthly utility bills.


Are vanadium solar-powered batteries safe?

Vanadium solar-powered batteries are safe for residential use. They are non-flammable and non-explosive. The electrolytes used in vanadium flow batteries are also water-based, making them the safest battery technology available.  

Are vanadium batteries better than lithium-ion batteries?

Vanadium flow batteries do not decay over time, maintaining 100% capacity for the life of the battery. Vanadium batteries also have a lifespan of more than 25 years, which is longer than most lithium-ion batteries. They are also more cost-effective than lithium-ion batteries.

Are vanadium flow batteries better for the environment?

Vanadium flow batteries are easier on the environment than lithium-ion batteries, as the vanadium electrolyte can be reused. This eliminates the need for additional mining.  Vanadium flow rechargeable batteries reduce carbon emissions significantly compared to lithium-ion batteries. Vanadium flow batteries are also nearly 100% recyclable.
