Tap a star to rate
Die Speicher Profis are headquartered in Herisau and serve customers in Appenzell Ausserrhoden and the rest of eastern Switzerland. The focus is on retrofitting battery storage onto existing solar systems, which is useful in a region with plenty of older installations.
The company's own storage calculator on the website gives a first estimate of the right capacity. The offering also includes wallboxes and bidirectional charging systems. Inquiries run directly through the website or by phone.
