The ViZn Energy Storage System delivers proven significant energy storage, operational savings, as well as increased value.

Commercial & Industrial

Demand reduction, load shifting, resiliency, energy capture and other revenue grade applications are supported by ViZn.


Renewable integration, load shifting, resiliency, TOU bill reduction and other grid stabilization services are supported by ViZn.


Congestion relief, Distributed generation, resiliency frequency regulation and other key applications are supported by ViZn.

Storage technology that changes everything

Widely recognized as the “holy grail”, energy storage is critical to delivering on the promise of a sustainable energy future. Storage will play the instrumental role in upgrading our current grid infrastructure by eliminating waste, improving reliability and supporting the widespread adoption of renewable energy.

An enabling technology

In the developing world, energy storage is the enabling technology to provide low-cost distributed energy microgrids to the 2.5 billion people with limited or no access reliable power.  As the world faces the challenges in the area of food, water and energy, ViZn recognizes the importance of our task at hand.

Low cost reliable energy is the catalyst for economic growth which in turn will lift billions out of poverty while supporting additional innovations in the area of food production and clean water. ViZn is committed to building a sustainable future for generations to come.

The promise of the flow battery

“Flow batteries are one of the top 3 technologies that Bill Gates thinks could save the world. “–Bill Gates announced at the Breakthrough Energy Coalition in December 2015. He told a group of 28 investors including Mark Zuckerberg, George Soros, and Richard Branson, that “the energy crisis isn’t just a matter of collecting energy. We also have to store it. Wind power and solar power are by definition intermittent, so it’s crucial to have a way to store that energy when the sun stops shining or the wind stops blowing. And, Flow-batteries that could last longer and hold more energy than lithium ion batteries is an example of innovation that makes a difference.”

Trends and Growth

The growing demand for an efficient, safe, and reliable energy storage battery in the renewable energy space is clear.

High Frequency Power Switching

Greater operating range and immunity to cycle life degradation enable fully dispatchable revenue grade power across full range of storage applications.


Access to 100% dynamic range of the SoC with no need to compensate for safety and life saving constraints in competing systems.

Advances in battery storage will be transformative for the developing world—and the planet.” -The Washington Post

In comparison to most battery systems, ViZn Energy Systems can use 30-40% more effective energy storage and discharge. This has considerable benefit when comparing to alternative battery technologies that cannot access the entire state of charge without damage or limiting life.

Duty Cycle

ViZn ESS is capable of punishing duty cycles without limitation or concern for breakdown or damage enables the ViZn battery support simultaneous revenue grade applications. .

Environmentally Safe

Our non-toxic, non-flammable, non-explosive system is housed in a non-pressurized container operating at ambient temperature.  More locations are available, permitting is easier, and more sites qualify for energy storage installation.

Quality manufacturing

ViZn partners with tier 1 ISO certified manufacturers to assure quality manufacturing and rapid deployment worldwide. Our manufacturing facilities are ISO90001:2008 and ISO 14001:2004 certified. A global footprint and integration ensures production capacity and fulfillment.


One unique battery for both long duration energy and high frequency power services.  Easily stack multiple planned or unplanned services to maximize income streams.


Deploy near densely populated areas and high value grid infrastructure. Runs on a safe chemistry that is non-toxic, non-flammable, and non-explosive.  Easy to recycle at end of life.


Superior ROI due to multiple income streams, 20-year life, lower O&M expense and negligible degradation across 100% state of charge.
