US power startup Bluetti has launched the world’s first sodium-ion solar generator.

The NA300 combines a 3kW pure sine wave 120Vac inverter with a 2kWh sodium-ion battery. Two units can be combined for a 6kW output at 240V.

The first-generation sodium batteries are comparable with lithium-ion ones. They charge to 80 percent SOC in 30 minutes at room temperature and keep over 85 percent capacity retention and over 80 percent system integration efficiency in sub-zero temperature (-20°C), a key advantage ovr lithium ion systems.

The Na300 is able to charge at 6,000W (3,000W Max. for both AC and PV) and works with two B480 battery modules (4,800Wh each) for 12,600Wh to provide power for up to week during grid failures or natural disasters with constant solar input.

The company also used CES 2022 to launch a 600W pure sine wave inverter with 288Wh LiFePO4 battery pack that supports a 600W Max. AC input and 200W Max. solar input for an entry-level power station. The EB3A is the first Bluetti compact model that doesn’t require a bulky power brick and takes 20 minutes to charge to 80 percent.
