BLUETTI debuts sodium-ion battery for home solar applications


BLUETTI, a manufacturer of solar + storage products, including LiFePO4 battery stations, is debuting a sodium-ion battery technology at CES 2022. Recently BLUETTI has announced the “world’s first sodium-ion battery station“, NA300, and its compatible battery module B480. Sodium-ion batteries have become an alternative to their lithium-ion counterparts in many industries due to their high abundance and low costs.

BLUETTI’s first-generation sodium-ion battery excels in thermal stability, fast-charging capacity, low-temperature performance, and integration efficiency, despite slightly lower energy density than its LiFePO4 ones.

The NA300 inherits all the style and appearance settings of its predecessor, EP500 Pro, especially four 20A plugs and one 30A L14-30 output port driven by the built-in 3,000W pure sine wave inverter. In addition, NA300 can be recharged to 80% in 30 minutes by 6,000W swift AC + PV dual charging. (3,000W Max. for both AC and PV), making it one of the fastest charging battery units for a solar application.

The NA300 only delivers 3,000 Wh capacity, less than EP500 Pro in the same size due to technical limitations. But it supports up to two B480 battery modules (4,800Wh each) for up to 12,600 Wh capacity, and the unit, recharged by solar panels, can serve a family’s electricity needs for several days or even a week during grid failures or natural disasters.

In a low-temperature environment of -20°C (-4℉), it still has an over 85% capacity retention rate and over 80% system integration efficiency. Therefore, NA300 & B480 are great in winter or regions with shallow temperatures.

Additionally, NA300 also offers connection with another NA300 by a fusion box (Output voltage and power double to 240V and 6000W, respectively), IoT App remote control, and other EP500 Pro’s merits.

Have you checked out our YouTube page?

We have a ton video interviews and additional content on our YouTube page. Recently we debuted Power Forward! -- a collaboration with BayWa r.e. to discuss higher level industry topics as well as best practices / trends for running a solar business today.

Our longer running side project is The Pitch -- in which we have awkward discussions with solar manufacturers and suppliers about their new technology and ideas so that you don't have to. We discuss everything from residential rail-less deck attaching and home solar financing to large-scale energy storage value stacking and utility-driven new home solar + storage microgrids.
