Sodium-ion solar generator debuts
The company, which manufactures solar energy facilities including solar generators, photovoltaic panels, and peripherals says it is now venturing to integrate sodium-ion battery technology into its upcoming solar products. Sodium-ion batteries offer an alternative to their lithium-ion counterparts in many industries due to their high abundance and low costs.
The company’s sodium-ion solar generator – NA300 and its compatible battery module B480 – inherits all the style and appearance settings of its predecessor – the EP500 Pro – especially four 20A plugs and one 30A L14-30 output port driven by the built-in 3,000W pure sine wave inverter.
The NA300 may be cited as the fastest charging solar generator, says the company, since it can be recharged to 80% in 30 minutes by 6,000W swift AC + PV dual charging (3,000W Max. for both AC and PV). However, the NA300 delivers a 3,000Wh capacity, less than ther EP500 Pro in the same size due to technical limitations.
The new generator supports up to two B480 battery modules (4,800Wh each) for a 12,600Wh 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 addition, the NA300 offers connection with another NA300 by a fusion box (output voltage and power double to 240V and 6000W, respectively) and IoT App remote control.
The company says its 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. It can charge to 80% SOC in less than 30 minutes at room temperature.
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, says the company, NA300 & B480 are perfect for winter or regions with shallow temperatures.
