This is a 48V 100Ah home storage battery built on sodium-ion cells instead of lithium, sold under the JM-48V100Ah model name with a 10-year warranty. Sodium-ion chemistry is the draw: it holds up better in cold and is less exposed to lithium supply swings, but it stores less energy per pound than lithium. That makes it a fit for a fixed wall-mounted backup or solar-storage install where weight and footprint matter less than durability and cost. Against lithium powerwalls it gives up some round-trip efficiency and energy density, so check the inverter's charge profile before committing.
