Performance, flexibility, reliability and safety
When it comes to storage modules, there are numerous solutions on the market from different suppliers. Here at Fronius, we made the decision to work only with the best, most reliable and safest technologies and manufacturers. Consequently, we offer the follwing storage system solution:
- the Fronius Energy Package with the Fronius Solar Battery, based on Murata Fortelion™ Technology
Both these storage systems are designed for maximum performance, flexibility, reliability and safety. They differ in storage capacity, visual appearance and in the installation options. The Fronius Solar Battery is based on lithium iron phosphate technology, currently the safest storage technology on the market. With storage capacities ranging from 3.6 to 9,6 kWh, the Fronius Solar Battery gives you maximum flexibility in creating your photovoltaic systems. Storage modules can also be retrofitted later on, without major expense. The battery, designed for indoor installation, is extremely durable: 8,000 or more charging cycles are not unusual under ideal operating conditions.
Fronius Energycell: long-term energy storage
With the Fronius Solar Battery, Fronius offers the most innovative solution currently available on the market for the short-term storage of energy – namely from day to night. We are also investigating solutions that allow energy to be stored efficiently over the long term, i.e. for weeks or months. One approach is the Fronius Energycell, which consists of an electrolyser and a fuel cell. The electrolyser uses the generated solar energy to split water into hydrogen and oxygen. The hydrogen is stored in a tank until the energy requirement is higher than the output of the photovoltaic system. The fuel cell then converts the stored hydrogen back into electrical energy. The waste heat generated as a by-product is not lost either, as it can be used to provide hot water and for heating back-up. This storage system is currently at the project stage. The Fronius Energycell is being tested and developed jointly with companies, universities and research facilities in numerous projects. Our innovation has already received several awards – including the World Energy Globe Award in 2007. With the Fronius Energycell, it will be possible in future to store self-generated solar energy efficiently and flexibly over a longer period as well.
