- The storage systems are scalable from 4kWh to multiple 100kWh depending on the application
- Extremely safe compared with Li-ion, and non-flammable
- Lifespan of 15 years for 70 percent usable capacity
- 100 percent depth of discharge (DoD)
- C-rate of 0.5C

|Product Value Proposition|
The main strength of this product is the safety and longevity (15 years, compared with 5 - 10 years for Li-ion), which may be enough to sway consumers. The capex compared to Li-ion is higher, but the opex should be lower due to the long lifetime.
|State of Technology/Product Development|
The product is commercialised, and the company expects to double its output to sales of around 500 systems in 2018.
|Medium-Term Commercial Opportunity|
The company benefits from a subsidy covering 30 percent of the capex in Austria, and other local and national subsidies in Germany. As more FiTs for residential PV owners expire in Germany, the addressable market for the company increases.
|IP and Know-How|
The company has patents and know-how for designs above the cell level. Cells are outsourced.
Competition is tough in Germany, the market which is the company's main hope for the future due to the expiring FiTs. The German market is highly fragmented: other pure play companies such as Sonnen, Senec and E3/DC having captured over half the market. Companies like Sonnen, who have a strong software platform behind their product that offers users additional benefits and services, will be difficult to compete with.
