This is a 48V 100Ah sodium-ion battery pack rated at 4.8 kWh, built for solar storage, off-grid power and backup systems. Sodium-ion chemistry is the draw: it holds up better than lithium in cold and is less prone to thermal runaway, and sodium is cheap and abundant. The trade-off is lower energy density, so it is heavier and bulkier than a lithium pack of the same capacity, and sodium-ion cells are newer, with fewer field years behind them. It suits buyers building stationary storage who value safety and cold-weather tolerance over light weight.
