UNIGRID announced it is delivering its first-generation sodium-ion residential batteries to U.S. customers. The lithium-free battery, Na+Casa, is the first residential design by the company.
Engineered for compatibility with most existing hybrid inverters, Na+Casa is designed to reduce the cost and complexity of residential solar retrofits. Built on UNIGRID’s proprietary NCO sodium-ion chemistry, the battery also supports a broader shift toward more resilient energy storage supply chains by reducing dependence on cobalt, nickel and volatile lithium markets in favor of abundant, responsibly-sourced sodium. Na+Casa is rated at 9.25 kWh capacity and is designed for a 25-year operational lifespan.
“As residential energy bills rise — especially during extreme weather events such as the record heatwave we are seeing around the world — homeowners need storage that is safe, reliable and financially sound,” said Darren H. S. Tan, CEO and co-founder of UNIGRID. “With Na+Casa, UNIGRID is moving NCO sodium-ion from just a promising technology to a tangible residential storage product, giving installers and integrators a lucrative alternative to lithium-ion.”
By using sodium-ion chemistry, the Na+Casa system eliminates any possibility of thermal propagation due to its lack of lithium. The battery operates across temperatures ranging from -40°C to 60°C (-40°F to 140°F), supporting use in regions facing freezing winters, intense heat or increasingly volatile weather.
News item from UNIGRID
We are looking at a Sol-Ark 18K inverter but cannot find information regarding compatibility with Sodium Ion Batteries. Our System is 13KW Solar Array and we need in the range of 25KWH storage. Where best to purchase a Battery pack of that size that will work with Sol-Ark?
Thanks for your help, look forward to hearing back.
