Decreasing and expiring feed-in tariffs are making increased self-consumption of photovoltaic electricity economically reasonable. The use of energy storage systems allows for a significant increase in self-consumption. Our ResiFlow storage system, based on the vanadium redox flow technology, is perfectly suited to a variety of storage applications.
Existing storage technologies are based on Li-ion or lead acid technologies which can have drawbacks in safety and durability. In contrast, the redox flow technology achieves a very high cycle life (>15,000 cycles) and is intrinsically safe against fire due to the use of aqueous electrolytes. Redox flow batteries have already been used successfully in large-scale installations (e.g. wind farms) since the 1980s.
Thanks to its modular setup, the ResiFlow storage system makes it possible to offer any power (2,5 - 20 kW) and capacity (10 - 100 kWh) depending on the customer's needs. Thus, the customers receive a product that fits perfectly to their PV system. The ResiFlow storage uses an innovative sealing concept that makes the key component smaller, lighter, and less expensive. Additionally, a patented electrode activation using plasma significantly increases the power output of the electrodes, enhancing the overall performance of the ResiFlow storage system.
Due to the general technological benefits of redox flow batteries combined with the innovations used in the ResiFlow energy storage system, the ResiFlow energy storage is an extremely attractive and marketable system for anyone who wants to increase their self-consumption!
