Technical FAQs 3

What is a sodium ion energy storage system?

The sodium-ion energy storage platform has been designed to overcome long-standing limitations of traditional lead-acid-based backup systems by offering up to 2-3 times longer life, significantly reducing operational costs and downtime. The storage system comes in 3.5Kw, 5Kw, and 10Kw models with in-built batteries.

What is energy storage sodium battery technology?

In the energy storage sodium battery technology, the sodium ion battery has better performance at high and low temperatures. The capacity retention rate is 70% at – 40℃, and it can be recycled at 80℃. At the level of energy storage system, the air conditioning power quota can be reduced, and there is room for cost reduction.
