Elecyr Smart Battery

The Elecyr Smart Battery

Solar power is rapidly becoming the least expensive electric power but solar panels only work when the sun is shining. That’s why solar+storage is the fastest growing segment of the renewable energy market. But batteries for solar have some restrictions too. To get to a high enough voltage to power a house, they need to be connected together in a string that needs electronic management and balancing. Unbalanced batteries can die a premature death and even catch on fire.

Elecyr is a specialist in battery management for all types of batteries from lead-acid wet cells to advanced lithium titanate. We know batteries and can guide you to the best choice for your application.

Our own smart batteries use long-life lithium iron phosphate batteries which we believe are the best choice for residential energy storage. Our LFP batteries have three to four times the life of of the lithium NMC batteries used in electric cars such as the Tesla. They also last up to twenty times longer than lead-acid batteries. Also, apps for Android and iPhone, as well as cloud based monitoring, extend the life of our batteries and provide detailed histories battery use.

Energy storage keeps you covered when the sun doesn’t shine.

Energy storage, once used just for a few minutes of battery backup, is now an important part of smoothing the flow of power for renewable power generation. A few years ago there were only lead-acid batteries. They’re ok for backup but don’t work well for daily deep discharge. In the past decade all sorts of new batteries have come to the forefront. The safest, most economical batteries for renewable energy storage are LFP batteries which are doubling in power density every decade. However, like all batteries in a large energy storage application, LFPs need continuous balancing, and that’s an Elecyr specialty.

The Applications

We've been working with cutting-edge battery storage since 2008, and our battery management, control systems, and intelligent distribution is unrivaled in the industry. While there exist other energy storage systems on the market, none of them are designed with modular scalability at their core.


Bringing Off-grid Power to Remote Regions

Utilizing the same principles that govern the Internet, our Digital Microgrids, when used in conjunction with any combination of renewable, fossil or grid power sources, create a fault tolerant, local power grid with no reliance on the existing grid infrastructure. This modular, adaptable microgrid can efficiently power hospitals, schools, an entire village - the opportunities are nearly limitless.


Zero Net Energy and Passive Home

The combination of an efficient envelope, advances in appliances and heating and DC LED lighting, make it possible for Zero Net Energy and Passive Homes to have total energy independence, often without any grid or fossil fuel generator backup. This can either be a no-compromise system to meet all possible peak loads, or a more aggressive load shedding and lifestyle management approach which is much less expensive but means that certain heavy loads can be run at the same time. Our  Solar Panel Calculator will help you fit the system to your lifestyle and budget.


Forward Operating Base Camps - Military Microgrids

By decreasing or even eliminating dependence on inefficient generator systems powered by fossil fuels, Elecyr's Digital Microgrids and mobile solar solutions provide renewable, reliable energy anywhere, eliminating the difficulties of synchronization, hot-swap repair, fault tolerance, and natural expansion. Digital Microgrids make expansion as easy as plugging in a generator and starting it up. When security, safety and reliability are paramount, Digital Microgrids are the absolute best solution to deliver power to our men and women in uniform.


Container and Modular Construction

Elecyr grid independent power systems are sized right to meet the meet all the power needs of modern energy efficient construction. Often one or two Daily Sun plug-and-play systems, perhaps along with a shared higher power inverter, can be installed in a few hours and provide all the power for the residence. The Daily Sun brings the same modularity and mass produced savings to the powering the dwelling that containers and modular construction have brought to the envelope.


Emergency Response Solar Generators

When disaster strikes, restoring power in an affected area is vital to the support of emergency services and recovery efforts. With the unpredictability of disasters, natural and otherwise, portable, reliable and scalable power solutions can make all the difference. Elecyr Digital Microgrids and solar generators provide an efficient "emergency grid" that can be dropped into any situation


Off-Grid Tiny House and RV

We have environmentally friendly power systems to take you off grid in comfort. Our Daily Sun and an optional generator (run occasionally and efficiently) provide the electricity, but we can also recommend components for energy efficient DC air conditioning and heating, cooking solutions, and LED lighting. Whether you are going tiny, modular, container of just off-grid, we have power systems that can match your needs.


Hybrid Electric Marine Propulsion

Electric propulsion of sail and power boats offers the same clean energy advantages as extended range electric cars. Until now there have been few solutions available to the boatbuilder. Elecyr Corporation closes this gap with standard components for assembling hybrid systems for boats ranging from 10-ton catamarans to 100-ton trawlers and schooners.

The whole solution

Elecyr is now the battery management supplier to The Digital Microgrid Initiative P.B.C., a public benefit company with the mission of bringing power to people all over the world where a power grid is either unavailable, unaffordabe, or unreliable.

DMI's first product is Simplicity, a complete off-grid solar power solution that can scale from a few kilowatts to megawatts and costs less in equipment and particularly in the soft costs of design and instalation..
