Storing power with an all-in-one solution

For more than three quarters of a year, Stefan Riedelsheimer has carefully looked into various storage technologies and manufacturers. The family man was looking for a technology alternative to lithium systems because he was not satisfied with the price-performance ratio.

Eventually he was convinced by the VoltStorage SMART all-in-one solution based on the eco-friendly vanadium redox flow technology.

Stefan Riedelsheimer about VoltStorage:

“I work in the technology sector myself and have already been in contact with larger redox flow systems. (…) After all, you come across the redox flow principle in many different areas. It was interesting to me because it’s not a young technology, since it has been around for some time.“

“In terms of technology and price, VoltStorage offers in my eyes the best price-performance ratio and I have to say: At this point, without VoltStorage I would not have bought any battery storage system.“

Storing power without Lithium

Manfred Mayr has spent his entire career working in research & development and is therefore enthusiastic about innovative solutions. He was in contact with VoltStorage from an early stage on and was one of the first to put the VoltStorage SMART home battery solution into operation, breaking new ground with the lithium-free storage system.

Manfred Mayr about VoltStorage:

„After I had installed my PV system, the question came up: which home battery to go for? Lithium-ion technology was not my preferred answer. I wanted to rely on something new.“

“By chance I read a newspaper article where VoltStorage introduced itself and the idea was born: That’s it! Then I read up thoroughly on the Internet and obtained additional information. (…) For environmental reasons alone, a VoltStorage battery system was the only option for me.“
