WattGrid Comparison to Tesla/Lithium Systems

There are a number of storage systems currently available in the Australian market. Most of these are Lithium systems. The WattGrid 10 and WattGrid 12 use Tubular gel batteries as it is a proven, safe and reliable technology that has enabled us to deliver a cost-effective system to the Australian market. So how do we compare to current TESLA/Lithium offerings?
