German-made in every aspect. Ever since Solarwatt was founded in 1993, all components have been manufactured in Germany. MyReserve battery provides you with solar energy from your photovoltaic system even when the sun is not shining. Now it can really pay off for you with Solarwatt. Many people previously found that the technology was too expensive, too complicated, and therefore unprofitable. But now we have MyReserve; the next generation of solar energy batteries with state-of-the-art technology and the ability to achieve around 80% independence from the grid. On good days this can be as much as 99% and this is done through optimal self consumption.
